Here is a survey of what you will find in this section:

Purpose • How to Cut Telephone Costs

•

Other Advantages and Applications RF Radiation Safety Precautions

•

1.1. Purpose

• The 2N - VoiceBlue Lite gateways help interconnect SIP based

• The voice mode, i.e. an outgoing or incoming call, is the basic

• In addition to voice transmission, the 2N - VoiceBlue Lite

• No extra equipment (an external GSM telephone, etc.) is

VoIP networks directly with GSM networks. They can also be used for a direct connection with a VoIP telephone set.

function of the system. The gateway is equipped with all functions necessary for such use and provides a very high comfort in this mode.

gateways enable to send and receive SMS messages.

needed for normal operation. To set the basic parameters use the configuration software included in the product CD. All programmable parameters are default-preset in such a manner that you can commence your telephone traffic the moment you connect the Ethernet and supply cables, antenna and SIM card and set the GSM and VoIP parameters.

1.2. How to Cut Telephone Costs

• Once you connect the 2N – VoiceBlue Lite gateway to your

VoIP PBX, you can make all outgoing calls to a mobile network directly. Thus, you cut your PSTN - mobile network call costs. All mobile telephone calls from your personnel in the field are cheaper too.

• You are advised to use the most advantageous rate of your

GSM provider for your GSM gateway because all gateway

user call accounts are added up for billing purposes.

• You can bar selected numbers or groups of numbers in your

gateway. You shall pay nothing for the calls you have barred.

• 2N - VoiceBlue Lite keeps detailed records on all calls. This

helps you find out easily why your bill is higher than it should be.

• The Least Cost Router is flexible enough to help you set rules

for GSM calling at the lowest possible operation costs.

• The intelligent Callback function enables your personnel to

call at the cost of your GSM gateway SIM cards.

1.3. Other Advantages and Applications

• 2N - VoiceBlue Lite integrates the best of the GSM and VoIP

communication technologies.

• The GSM gateway keeps detailed statistics on incoming and

outgoing calls.

• With the Compact Flash memory you get an almost unlimited

depository for your call records.

• The Intelligent Routing of Incoming Calls function

accelerates the incoming call establishing and provides a higher calling comfort.

• The DISA function with the option to record easily a welcome

note is available.

• You can use the conditioned or unconditioned call forwarding

function.

2N - VoiceBlue Lite

• You can disable the CLIP function on your GSM telephone set.

• Unlike mobile telephones, this system does not expose you to

the RF electromagnetic field while making calls.

• All functions may be configured through the Ethernet, USB

and serial interfaces.

• With the aid of external software, you can implement your

VoiceBlue Lite gateway into the Unified Messaging system of your company.

1.4. RF Radiation Safety Precautions

It is prohibited to use any transmitters, including VoiceBlue Lite, in areas where explosives are used, such as quarries.

It is forbidden to use mobile phones and thus VoiceBlue Lite too at refuelling points.

A GSM gateway may affect sensitive life-saving devices in medical centres. So it is prohibited to use mobile phones and thus VoiceBlue Lite here.

In general, any restriction regarding mobile phones

ased on RF energy radiation applies to GSM

gateways. Where necessary, VoiceBlue Lite may be installed

at a safe distance (in the neighbouring building, e.g.) and an Ethernet cable may be carried from the GSM gateway to the original building.

Although GSM gateways are not intended for aircraft or cars, all relevant restrictions and regulations regarding mobile phones apply to them here.

SECTION 2 –

Installation

2N - VoiceBlue Lite

This section deals mainly with the proper mounting of the 2N VoiceBlue Lite and its connectors. One subsection is devoted to the lithium battery replacement.

Here is a survey of what you will can in this section:

Get Started • Brief Installation Guide

•

Proper Mounting PC or LAN Connection • Antenna Connection • Gateway Power Supply • SIM Card Installation/Removal • PIN Entering Disable (Optional) • Status Indicators •

Lithium Battery Replacement • Fuse Replacement • Antenna Splitter •

2.1. Get Started

Before you start installing your VoiceBlue Lite gateway, get familiar with its physical structure, arrangement of connectors and status indicators; see

Fig. 1, Fig. 2, and Fig. 12.

Fig. 1 – Bottom View

2.2. Brief Installation Guide

• Proper mounting – 2N – VoiceBlue Lite is designed for

suspension on a vertical surface. Fit the holder included in the delivery on a wall and hang the gateway on it. For details on the prescribed working position and other recommendations refer to Subs. 2.3.

2N - VoiceBlue Lite

Fig. 2 – Top View

• Cable connection – connect the gateway using an Ethernet

cable to your VoIP PBX (or any other VoIP terminals). For more details on proper wiring refer to Subs. 2.4.

• Antenna connection – connect an external antenna cable into

the SMA antenna connector. Place the antenna on a place with a good GSM signal (refer to Subs. 2.5).

• Gateway power supply – the delivery includes a mains

adapter. Make sure that an antenna has been attached to the antenna connector before supplying voltage. Plug in the adapter connector into the GSM gateway and the power adapter into a wall socket. The gateway turns on immediately (see Subs.

2.6).

• SIM card insertion – SIM cards are inserted in holders on the

gateway top. The SIM card holder is of the push/pull type, which means that all you have to do is insert a SIM card and press the holder gently until it snaps into position (see Subs.

2.7). Secure the SIM card with a latch to avoid incidental removal. !CAUTION! If you use PIN-asking SIM cards, first

set an identical PIN code for all SIM cards used in the GSM gateway, save it into the GSM gateway configuration and only then insert the SIM cards in the GSM gateway.

• PC connection – the gateway parameters are normally set

using the configuration software available on the CD included in the delivery. To interconnect your PC with 2N - VoiceBlue Lite use the USB cable

* **

or laplink RS 232 cable included in

the delivery.

• Configuration program installations - run the installation

file from the installation CD on a PC connected to the gateway and install the VoiceBlue Lite configuration software

(refer to Subs. 0).

• Configuration program - run the VoiceBlue Lite program and

set the serial port communication for your PC - gateway connection. Establish communication between your PC and the gateway (refer to Subs. ).

• 2N - VoiceBlue Lite configuration - now use the

configuration software to set all necessary gateway parameters

- VoIP parameters basic GSM parameters and tariff metering/pricing parameters, routing, restrictions, system parameters, and input and switch properties. Having set the required parameters, upload the configuration data to the gateway via a serial link. For more details on the configuration software see Section 9.

Be sure to install the drivers available on the CD included when you use a USB cable.

**of the same type as used for direct PC-PC connection.

2.3. Proper Mounting

• The 2N - VoiceBlue Lite gateway is designed for mounting on

a vertical surface. For this purpose a wall- mounting holder is available. Just fit the holder with dowels and screws (Fig. 3) to the wall and hang the gateway as shown in (

2N - VoiceBlue Lite

Fig. 4).

Fig. 3 – Gateway Holder Wall-Mounting

Fig. 4 – Gateway Hanging

• It is possible to operate the VoiceBlue Lite gateway in another

working position (e.g. on a desk) for a short time only, for example in servicing centres for quick testing purposes.

• Exceeding the recommended operating temperature values may

not affect the gateway function immediately but may result in more rapid ageing and lower reliability. The allowed working temperature and relative humidity ranges are included in Section 12.

• The gateway is intended for indoor use. It may not be exposed

to rain, flowing water, condensed moisture, fog, or mist.

• The gateway may not be exposed to aggressive gas, acid

vapours, solvents, etc. or aggressive liquids, during cover cleaning, for example.

• The VoiceBlue Lite gateway is not designed for high-vibration

environments e.g. means of transport, machine rooms, etc.

• Free space has to be left under and over the gateway for cables

and agitated air to remove operational heat.

• Install the gateway on a place with a good GSM signal.

• A misplacement of the GSM gateway or its antenna near

television, broadcasting or similar RF-sensitive devices may evoke an adverse effect upon their function.

• Being a source of RF energy emission, the VoiceBlue Lite

gateway antenna should not be located close to human bodies. The hazard is higher than with mobile telephones because the gateway is usually used by many people and thus employed more often.

2.4. PC or LAN Connection

The 2N - VoiceBlue Lite gateway can be connected to a PC using a USB cable terminated with a USB B connector or a laplink serial cable with RS 232 connectors. A direct connection of 2N - VoiceBlue Lite and a PC is necessary for the initial gateway configuration when the gateway IP address is unknown and the gateway cannot be configured using the LAN.

VoiceBlue Lite supports connection via the Universal Serial Bus (USB) of version 1.1. In this type of connection, however, it is necessary to install VoiceBlue Lite drivers into your operating system (OS). At present, the drivers support the Microsoft

2N - VoiceBlue Lite

Windows 98SE/ME/2000/XP OS. While installing the drivers please following the instructions below:

• Insert the included CD into your PC CD-ROM drive.

• Connect the USB cable to the PC and then to VoiceBlue Lite.

• The Windows OS recognises the connected device

automatically and asks for suitable drivers.

• Find the VoiceBlue Lite drivers on the CD included in the

delivery in the following directory: CDROM:\VoiceBlue\USB

drivers.

• The OS recognizes the right drivers automatically and starts

installing them.

The OS may also require the USB COM port drivers. They are available in the same CD directory as mentioned above.

The VoiceBlue Lite gateway operates as a modem in the data mode, communicating through a virtual COM port. The gateway USB port default parameters are 921,600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. If you intend to use the USB cable for distances longer than 5 meters, you are recommended to use the USB hubs.

Fig. 5 – Direct PC Connection Using USB

The serial port transmission rate is 57,600 bps, the remaining communication parameters are the same. Set the communication parameters on the PC side identically.

Fig. 6 – Direct PC Connection Using RS232

A standard straight through cable terminated with RJ-45 connectors is sued for connection to the 10BASE-T (Twisted Pair Ethernet) LAN (Fig. 7 and Fig. 8).

Fig. 7 – LAN Connection

Fig. 8 – RJ-45 Wiring for LAN Connection

2.5. Antenna Connection

The VoiceBlue Lite gateway has one SMA antenna connector for all GSM modules, see Fig. 9. An external antenna cable is connected to this connector. The external antenna should be installed vertically on a place with a good GSM signal. For the technical parameters of the antenna refer to Section 12.

2N - VoiceBlue Lite

Fig. 9 – Antenna Connection

Tighten the antenna connector gently with your hand, never use a wrench!

2.6. Gateway Power Supply

• Be sure to use only the mains supply adapter that is included in

the gateway delivery.

• Before plugging in the gateway, make sure that the mains

voltage value meets the data given on the mains adapter label.

• Make sure that the antenna has been connected. If you connect

the gateway to the power supply without an antenna, the GSM module transmitter might get damaged.

• Now plug the supply adapter into a wall socket and after it

connect the adapter connector to the gateway, see Fig. 10. The status indicators indicate the proper operation. For their meanings refer to Subs. 2.9.

Fig. 10 – Supply Adapter Connection

2.7. SIM Card Installation/Removal

Insert the SIM card into the SIM card slots with your hand as shown in Fig. 11. Please make sure that the slashed SIM card side is on a side opposite to the latch. Having inserted the SIM card, push the card gently until you hear a click signalling that the push/pull holders have snapped the card. Secure the SIM card by shifting the latch to the right in order to avoid incidental removal of the SIM card.

To remove the SIM card take the opposite steps. You can replace a SIM card even with the gateway on.

2N - VoiceBlue Lite

Fig. 11 – SIM Card Inserting Procedure

Each SIM card inserted in the gateway has a unique set of parameters. Their values are bound to the card IMSI, remain stored in the gateway even if the SIM card has been removed and thus need not be reset upon SIM card re-insertion.

2.8. PIN Entering Disable (Optional)

2N - VoiceBlue Lite is set at automatic PIN entering by default (1234). To disable the PIN use any mobile telephone in which you insert the given SIM card. By disabling the PIN entering you invalidate any other VoiceBlue Lite parameters or PIN stored in the gateway memory. If you do not disable this function, VoiceBlue Lite will always ask for a PIN by LED signalling, which must be identical for all SIM cards inserted.

2.9. Status Indicators

There is a panel with five LEDs on the gateway upper cover for a quick GSM gateway status detection (see Fig. 12). The Power LED signals that the gateway as a whole is in operation. The GSM 1 to GSM 4 LEDs indicate the status of the respective GSM modules.

Fig. 12 – Signalling LEDs

Basic diagnostic tests and gateway initialisation are performed automatically whenever the gateway is connected to supply voltage. Each test step is signalled by a specific colour combination of the LEDs. If a test step fails, the indicator combination related to the failed test remains lighted.

Power Indicator

The Power LED signals whether the VoiceBlue Lite gateway is supplied or not.

No light The system is not working. /

Continuous light The system is working.

GSM Indicators

The GSM 1 to GSM 4 LEDs signal statuses of the respective GSM modules. Whenever the 2N - VoiceBlue Lite is started, detection of the GSM modules is carried out. This process is signalled by a green LED. If all GSM modules are present and ok, the LED goes out. After that the firmware and configuration uploading process is initiated, which is signalled by various LED colour combinations. The initialisation process is followed by a check of presence of SIM cards in slots. Quick blinking of the green LED of the respective GSM module indicates this procedure. If a GSM

module or a SIM card is absent, the red LED remains lighted. If a GSM module is not supplied, the respective GSM LED is blinking red. Upon a correct GSM module initialisation, the SIM card is logged in, which is signalled by a quickly blinking green LED. If the log-in has been successful, the LED goes out. If not, it shines red continuously.

In normal operation, a continuous green LED indicates an incoming or outgoing call within the particular GSM module.

A survey of GSM module status signalling is included in Tab. 2.

Limited warranty on accumulators

The warranty on batteries (accumulators) supplied separately or as part of a product or together with a product does not also apply to wear and tear of accumulators and their components as a result of normal use (e.g. discharge of the battery, reduction of the accumulator capacity as a result of wear and tear) as fact that may not be deemed as a lack of conformity with the contract of sale in accordance with Article 2 of Directive 1999/44/EC of the European Parliament and of the Council.

2N - VoiceBlue Lite

WARNING! An incorrect battery replacement may result in explosion. For replacement, batteries

of the same or equivalent type as recommended by the manufacturer may be used only. The battery

type is CR2032. WARNING! Never use metal tools for battery

replacement to avoid short-circuit. Battery shortcircuiting may result in battery destruction or explosion.

Keep the proper battery polarity. Dispose of used batteries in accordance with

applicable waste regulations, for example in waste recycling centres.

Fig. 13 – Motherboard Diagram

It is unnecessary for the gateway function. Its average service life is approximately 3 years. You are recommended to replace it after three years for preventive purposes or, at least, check the voltage with a voltmeter (the value should not drop below 2.9V). A completely low battery results in the VoiceBlue Lite gateway losing the time and date information and false data appear in the trace and also in the service log buffer listing.

To replace the lithium battery, first disconnect your VoiceBlue Lite gateway from the mains and open the cover. Remove the old battery from the holder using a suitable tool and install a new one. We recommend you to have this service done by a 2N servicing centre.

2.11. Fuse Replacement

To exchange the fuse disconnect power adapter cable first. The location of the fuse on the main board is on the Fig. 13. Open the cover, remove the faulty fuse and check it. Replace the fuse by a fuse of the same type only. Close the cover and reconnect the power adapter cable.

2.12. Antenna Splitter

The antenna splitter is a passive component that enables several GSM channels to share a single antenna. With VoiceBlue Lite it joins four antenna ports into one external antenna. This splitter saves both antenna costs and installation space. It is a passive element – it has a characteristic signal attenuation that the connected antenna must compensate. For technical parameters of the splitter and antennas refer to Section 12.

WARNING! Use only a fuse of the same type. Disconnect the adapter power while replacing the

fuse. Fuse can be replaced only by service which is

personnel qualified to check such parameters as power consumption, DC voltage etc.

If fuse fails again, unit must be returned to manufacturer for repair

Proper Installation Conditions • VoiceBlue Lite Installation • Potential GSM Network Problems •

3.1. Proper Installation Conditions

The following installation conditions must be met for a proper function of VoiceBlue Lite:

• Sufficient space for VoiceBlue Lite installation.

• Sufficiently strong signal from the GSM network with which

VoiceBlue Lite shall work with (the minimum signal intensity value is –80dBm). To measure the signal intensity before VoiceBlue Lite installation you can use a mobile telephone with the Net monitor function enabled (e.g. SIEMENS, NOKIA).

• A corresponding capacity of the GSM network (no GSM cell

overloading). Remember that the use of multiple GSM gateways in one location may overload your current GSM cell base. This might lead to a permanent or occasional rejection of calls to GSM networks!

• No strong electromagnetic radiation on the installation site.

2N - VoiceBlue Lite

• No strong reflections on VoiceBlue Lite antenna sites.

• A correct VoIP connection configuration according to SIP

and other VoIP recommendations.

3.2. VoiceBlue Lite Installation

• Place the VoiceBlue Lite GSM gateway to an environment that

meets the gateway working conditions.

• It is recommended to connect the supply adapter with a battery

backup (UPS) and appropriate surge protection.

• Configure the GSM gateway using the VoiceBlue Lite software

available on the product CD enclosed.

• You may use remote GSM gateway administration through the

Ethernet for a comfortable GSM gateway management.

3.3. Potential GSM Network Problems

The VoiceBlue Lite GSM gateway is designed for a continuous 100% load. The GSM network may cause the following problems:

• The GSM module(s) cannot log in, log in slowly or log out

occasionally. This might be caused by any of the events below:

• The signal intensity received from the GSM network is too

weak – the recommended minimum value is -80dBm. If the signal is lower, change the antenna position or type.

• The GSM cell to which the GSM modules log in is

overloaded. Change the antenna position, or reduce the number of GSM channels connected to the troubled GSM network.

• One of the GSM modules keeps logged out or is unable to

process an outgoing call – this indicates a potential GSM network overload on the installation site. To solve this problem, set the parameter “Relax delay” = 2. If a GSM module fails to log in or refuses to process a GSM call even after the gateway restart, check your GSM network provider for potential SIM card or GSM module blocking.

SECTION 4 –

VoiceBlue Lite Connection to VoIP

This section discusses VoIP connection possibilities of the 2N VoiceBlue Lite gateway. Since 2N - VoiceBlue Lite communicates using the SIP only, the interconnection of SIP and H.323 networks is mentioned here too. 2N Point-to-Point or Point-to-Multipoint mode with a SIP Proxy server.

Point-to-Multipoint Configuration

- VoiceBlue Lite may be operated in the

4.1. SIP and H.323 Network Interconnection

SIP-based devices cannot communicate with H.323-based ones directly but through a SIP/H.323 gateway. This gateway transfers signalling reports of both the protocols. Using the RTP (Real Time Protocol) for multimedia data transmission, both SIP and H.323 devices can communicate directly with each other after getting interconnected by a SIP/H.323 gateway. Therefore, 2N - VoiceBlue Lite may be implemented into the existing H.323 environment using a SIP/H.323 gateway.

2N - VoiceBlue Lite

Fig. 14 – SIP – H.323 Network Interconnection

4.2. Point-to-Point Configuration

In the Point-to-Point mode, VoiceBlue Lite can only communicate with one SIP VoIP telephone or another SIP VoIP terminal, e.g. a VoIP gateway. The IP address of the opposite side is always set as the Proxy server IP address in the VoiceBlue Lite P-T-P mode.

The VoiceBlue Lite configuration with one SIP VoIP telephone is often used for testing purposes before implementation to the VoIP network. For this connection see Fig. 15.

Fig. 15 – Point-to-Point Configuration with SIP VoIP Telephone

In the Point-to-Point mode using a VoIP gateway, all calls assigned to GSM are routed to VoiceBlue Lite by the VoIP gateway. You can either set the IP address of the opposite side as the Proxy server IP address for the two terminals, or, with an intelligent VoIP gateway, resend certain calls to the VoiceBlue Lite IP address directly.

Fig. 16 – Point-to-Point Configuration with VoIP Gateway

4.3. Point-to-Multipoint Configuration

The Point-to-Multipoint arrangement means a classical structure of a distributed VoIP network with one or more SIP Proxy servers (VoIP gateways). The SIP Proxy is a software PBX version (or a standard PBX enhanced with VoIP services), which manages all signalling in the VoIP network. In this mode you can use multiple source terminals (e.g. VoIP telephones) and multiple destination terminals (e.g. VoiceBlue Lite). An internal routing algorithm (LCR) of your SIP Proxy is used for routing calls to GSM and other networks. GSM calls may be routed through the VoiceBlue Lite gateway. All signalling (SIP) is managed by the SIP Proxy and the subsequent voice stream is transmitted by the RTP in the Point-to-Point mode.

IP Voice Transmission

This section explains voice coding in IP networks. Moreover, essential facts are mentioned on establishing connection between two SIP-based IP telephones.

SIP Reports

5.1. Speech Coding Methods

Voice and signal transmission is strictly separated in VoIP networks. The RTP (Realtime Transport Protocol) is mostly used for voice transmission in modern VoIP networks. The purpose of the RTP is to transmit data from the source to the destination and ensure the real time data (voice) transmission.

Codecs are used to save capacity of data channels, processing the voice signal using various algorithms with the aim to minimise the volume of user data. The degree of compression used by codecs influences the quality of voice to be transmitted. This means that the higher voice quality is required, the wider data band (transmission rate) should be used. The voice transmission quality is evaluated using the Mean Opinion Score (MOS) where 1 means the lowest and 5 the best quality. A survey of codecs supported by VoiceBlue Lite is included in Tab. 3.

Codecs Supported by 2N - VoiceBlue Lite

Standard Algorithm MOS

G.711 PCM 64 4.1 G.726 ADPCM 32 3.85 G.729 CS-ACELP 8 3.92 G.723.1 ACELP 5.3 3.65

Transmission

rate [kb/s]

2N - VoiceBlue Lite

Tab. 3 Table of Codecs Supported by 2N® - VoiceBlue Lite

To achieve a high-quality voice transmission requires not only keeping of a constant necessary transmission rate during the whole connection but also a constant low data packet transmitting time.

Multiple the above mentioned rate by eight (four full duplex calls) and add the transmission rate necessary for the TCP and IP header to the resultant value for to get a successful 2N Lite Lite connection.

- VoiceBlue

• G.711 – this codec us used in digital telephone networks. The

Pulse Code Modulation (PCM) is used for speech signal coding. The sampled signal is coded by 12 bits and then compressed to resultant 8 bits using a transformation characteristic. The A-law compression is used in Europe, and μ-law compression in North America and Japan. The resultant data flow is 64 kbps.

• G.726 – this codec uses the Adaptive Differential Pulse Code

Modulation (ADPCM). This algorithm provides compression of 8-bit samples of codec G.711 into 2, 3, 4 and 5-bit samples with the resultant transmission rate of 16, 24, 32 and 40 kbps.

• G.729 – this codec uses the Conjugate-Structure Algebraic-

Code-Excited Linear-Prediction (CS-ACELP) with the resultant transmission rate of 8 kbps. The speech signal is split up into blocks of 10 ms each. The parameters of these blocks are then entered into frames of the size of 10 bytes. 2 byte frames are generated for noise transmission.

• G.723.1 – this codec uses the Multipulse Maximum Likelihood

Quantisation (MP-MLQ). The voice signal is split up into 30 ms blocks and coded into 24 byte frames with the resultant data flow of 6.3 kbps. Another coding algorithm is the Algebraic Code-Excited Linear Prediction (ACELP), which provides coding of 30 ms blocks of speech into 20 byte frames with the resultant transmission rate of 5.3 kbps. 4 byte frames are used for noise transmission.

During call establishing, a codec is selected automatically for voice transmission. 2N - VoiceBlue Lite is ready to use any of the codecs included in Tab. 3. The type of coding depends on your VoIP network (terminals) and VoiceBlue Lite GSM gateway configuration. The primary purpose of 2N - VoiceBlue Lite is to provide connection to corporate VoIP networks and it tries to meet the opposite side's codec requirements. If a codec incompatible with VoiceBlue Lite is required, the call is rejected.

The IETF SIP and ITU-T H.323 protocols are mostly used for making, maintaining and terminating connections. The 2N - VoiceBlue Lite gateway uses the SIP (Session Initiation Protocol).

5.2. SIP Components

SIP reports are transmitted between the following components:

• UAC (User Agent Client) – a terminal Client that initiates SIP

signalling;

• UAS (User Agent Server) – a terminal Server that responses to

SIP signalling from a UAC;

• UA (User Agent) – a SIP network terminal (SIP telephone, or

gateway to other networks), contains a UAC and UAS;

• Proxy server – receives connection requests from a UA and

transfers them to another Proxy server if the particular station is beyond its control;

• Redirect server – receives connection requests and sends them

back to the requester including destination data instead of sending them to the calling party;

• Location server – receives registration requests from the UA

and updates the terminal database with them.

2N - VoiceBlue Lite

All server sections (Proxy, Redirect, Location) are typically available on a single physical machine called Proxy server, which is responsible for client database maintenance, connection establishing, maintenance and termination, and call directing.

The 2N - VoiceBlue Lite gateway is always a UA (has the same functions as a VoIP telephone), i.e. receives call requests and directs calls to GSM networks according to the internal LCR.

There are no SIP-defined server sections in the 2N - VoiceBlue Lite gateway.

5.3. SIP Reports

Here is a list of main signalling reports sent in the SIP environment:

• INVITE – connection establishing request;

• ACK – acknowledgement of INVITE by the final message

receiver;

• BYE – connection termination;

• CANCEL – termination of non-established connection;

• REGISTER – UA registration in SIP Proxy;

• OPTIONS – inquiry of server options.

Replies to SIP messages are in the digital format like in the http protocol. Here are the most important ones:

• 1XX – information messages (100 – Trying, 180 – Ringing,

183 - Progress);

• 2XX – successful request completion (200 – OK);

• 3XX – call forwarding, the inquiry should be directed

elsewhere (302 – Temporarily moved, 305 – Use Proxy);

• 4XX – error (403 – Forbidden, 486 – Busy here);

• 5XX – server error (500 – Server Internal Error, 501 – not

implemented);

• 6XX – global failure (606 – Not Acceptable);

CHAPTER 6

Mobility extension

The function mobility extension (ME) allows the rerouting of a call from VoIP to the GSM network if a subscriber is unavailable in the VoIP network. Apart from this function it allows the holding of a call and forwarding calls from the GSM to VoIP network.

In this chapter you will find:

2N - VoiceBlue Lite

• High voice quality EFR/AMR

6.2. Activation of service mobility extension

The function mobility extension is an added value of the of

VoiceBlue Lite, and it can be activated using a licence key. In

2N order to receive a licence key, please contact your distributor. The licence key is entered in the GSM gate from the terminal window (see chapter 9.4) using an AT order.

6.3. Description of service mobility extension

The service mobility extension allows the rerouting of calls from the VoIP network to the GSM network in the case of the unavailability of the subscriber in the VoIP network. If the function mobility extension is permitted for a given subscriber, it is possible to switch off/on the rerouting of calls using the DTMF option from the GSM network.

Function “Follow me”

Fig. 19 - Service mobility extension function “Follow me”

Fig. 19 shows the routing of calls in the case of the absence of a subscriber in the VoIP network. Subscriber A calls subscriber B, who has the service mobility extension permitted with the active function “Follow me”. Subscriber B does not take the call in the VoIP network, so the call is rerouted to his mobile telephone.

Function “SMS at no answer”

In the case of a missed call in the VoIP network, the service mobility extension allows the sending of an information text announcement. This function is called “SMS at no answer” and is described in. In the same way as rerouting of calls, it is possible using the DTMF option to activate and deactivate the service of sending text announcements for missed calls.

2N - VoiceBlue Lite

SMS

Fig. 20 - Service mobility extension function “SMS at no answer”

Fig. 20 shows the sending of information texts if an incoming call is not taken.. Subscriber A calls subscriber B, who has the permitted service of mobility extension with activated services “Follow me” and “SMS at no answer”. Subscriber B does not take the call in the VoIP network, and so the call is rerouted to his mobile telephone. Subscriber B does not take the call even on his mobile telephone, and so he is sent a text announcement telling him that the call from subscriber A had been missed.

Function of forwarding call

In addition to the rerouting of calls in the event of absence, the function mobility extension allows calls to be forwarded within a VoIP network, which brings the services of the SIP proxy to a mobile telephone. The description of this function is displayed in Fig. 21.

Fig. 21 - Service mobility extension function forwarding call

In Fig. 21 subscriber A is talking to subscriber C, who has the permitted service mobility extension. Subscriber A would like to be forwarded to subscriber B. For this reason subscriber C holds the call with A (in the default setting 7*), and then calls subscriber B. He tells B that he will forward the call and then forwards the call (in the default setting 7*). If subscriber B does not want to talk to subscriber A, subscriber C terminates the call with B (in the default setting 9#) and returns to the call with A.

Function of quick forwarding of call

In Fig.22 subscriber A is talking to subscriber C, who has the permitted service mobility extension. Subscriber A with telephone number 111 would like to be forwarded to subscriber B with telephone number 123. Subscriber C wants to forward the call without having to talk to subscriber B. So subscriber C at first puts the call with A on hold (in the default setting 7*), and then dials

2N - VoiceBlue Lite

the quick forwarding character (default value #) and then dials the telephone number of subscriber B. He terminates the selection with the character of end of dialling (default value #). After the VoiceBlue receives the character of the end of selection, it terminates the call between A and C and attempts to make a call between the subscribers A and B. Subscriber A then receives a ring tone.

Fig.22 - Service mobility extension function quick forwarding

6.4. Recording announcements for mobility extension

Announcements for mobility extension can be recorded using the configuration program (see chapter 9.4) or using AT orders and the protocol X-modem shown below. Announcements of mobility extension are recorded only for subscribers who have this service activated (see chapter). The function mobility extension uses the list of announcements shown in Tab. 4 - list of announcements of service Mobility extension

• After the insertion of an order you will be called upon to select

the name of the audio file under which the announcement from VoiceBlue is to be filed.

Deleting of announcements

You can gain information about a loaded announcements using the AT order at!m#=view. To delete an announcement, enter the order at!m#=erese in the terminal window, where instead of # fill in the number of the announcement.

6.5. Permitting service mobility extension

As has been stated above, in order for the service mobility extension to be permitted for the individual subscribers it has to be first activated using a licence key. The permitting of mobility extension for subscribers can be performed using the mobility extension table. Its description is given in chapter 9.5. If in this table the CLIP of a mobile subscriber and his url is not given, this function is not permitted for the subscriber.

SECTION 7 –

2N VoiceBlue Lite Routing Rules

This section explains how to set the call routing rules to make the most of the gateway potential and minimise your telephone costs.

This section includes:

Functions Supported by 2N VoiceBlue Lite • Call Routing Rules • LCR table • Call Routing to GSM via VoiceBlue Lite • Incoming calls from GSM to VoIP network • DISA Message •

7.1. Functions Supported by 2N VoiceBlue Lite

• Call routing according to time and called destination through

the destination's operator;

• Call re-routing;

• Intelligent incoming CLIP routing (CLIP-based call routing);

• Outgoing call routing by time LCR (Least Cost Routing);

• DISA (tone dial-in);

• CallBack to GSM;

• Dial-in to the operator;

• SMS sending/receiving;

7.2. Call Routing Rules

Calls from a VoIP port to a GSM network are routed according to the LCR (Least Cost Routing) table to an arbitrary GSM port. If an outgoing call is routed via a port that is busy, the remaining available ports are searched for (depending on the configuration) and if no allowed outgoing port is free, the outgoing call is rejected.

2N - VoiceBlue Lite

The routing algorithm routes outgoing calls according to the outgoing call type, current time rate, day in a week, and GSM provider's free minutes if any.

Incoming calls from a GSM network are routed directly to the defined SIP address, or the DISA function is enabled. The CLIP function can be used too.

7.3. LCR table

The LCR (Least Cost Routing) table is the key telephone cost cutting factor. It helps you set the call routing rules according to the CLIP, daytime and day in a week. By entering public holidays into the LCR table you achieve even more remarkable cuts.

To make call routing to external ports based on prefixes and the LCR table work properly, define the prefix and the total count of digits to be dialled into GSM in the Network list. The SIM card inserted in the GSM gateway must be compatible with the defined

group. To assign a group to outgoing and incoming calls use the GSM groups assignment table.

During call establishing, the LCR table is checked line by line from top to bottom. If the called destination prefix matches the network prefix included in the Network list (called Network ID in the LCR table), the call is routed according to the routing group (Groups in the LCR table) as set in GSM outgoing groups. The call is connected via the GSM module assigned to the GSM outgoing group in the GSM groups assignment table.

If the selected GSM module is busy, another routing rule included in the Groups menu and defined by GSM outgoing groups is used. Again, an outgoing GSM group is assigned to the GSM module in the GSM groups assignment table.

The LCR line is processed in the above-mentioned way until a free GSM module is found. If no suitable GSM module is found (GSM outgoing group), the call is rejected.

7.4. Call Routing to GSM via VoiceBlue Lite

The outgoing GSM call routing algorithm starts the moment the SIP Proxy routes an outgoing call to VoiceBlue Lite.

Outgoing calls are routed via VoiceBlue Lite as follows:

• The calling subscriber dials a number that is routed to

VoiceBlue Lite by the SIP Proxy. It depends on your SIP Proxy configuration whether or not outgoing GSM calls are routed to VoiceBlue Lite.

• The dialled prefix is first compared with the prefixes included

on the first line of the LCR table. If no match is found, the following line is used for comparison.

• If the prefix matches a LCR prefix, the call time is checked for

match with the routing rule on the line. Again, if no match is found, the following LCR table line is searched.

• In case the prefix and call time comply with the routing rules,

the call is routed according to the first routing rule included in Groups and GSM outgoing groups to the module defined in GSM groups assignment.

2N - VoiceBlue Lite

• If the selected GSM module is busy or has an insufficient

credit, the preceding step is repeated for the following line of the Groups section. If there is no record, the next LCR table line is searched.

• In case the selected GSM module is free and has a sufficiently

high credit, the GSM gateway starts dialling the GSM number.

• If the calling subscriber number has an unknown prefix, or all

routes are busy, the GSM gateway rejects the call request.

• An outgoing call is not billed until the called party answers the

call.

• The GSM network signals the off-hook and the GSM gateway

transfers this information to the SIP Proxy.

• You can enable transmission of a connecting tone for

outgoing GSM calls, which replaces the silent moment between the request sending and ringing tone.

This posibility is for TC35i modules only

Fig. 23 – Routing of Outgoing GSM Calls

7.5. Incoming calls from GSM to VoIP network

Incoming calls from the GSM network are subjected to the algorithm described in Fig. 24 and the following steps:

An incoming call is handled depending on how the parameter “Mode” is set in the table “GSM incoming groups”. Here it is possible to set several possibilities:

• Reject / Ignore of incoming calls – incoming calls will not be

routed to the VoIP network. On the side of the GSM network a request for connection can either be rejected or ignored (the caller ringing tone)

• Report to PC – information about an incoming call is sent to a

PC with a servicing program. The caller is then played an announcement or dial tone. The servicing program then ensures the remaining routing of the call.

• If none of the above possibilities is set, an enquiry is made as

to whether the function Callback is activated. If for incoming calls the function Callback is activated, the callback table is searched. If the callback function is not permitted for the given CLIP (CLIP is not contained in the table Callback), the call is either refused or ignored depending on the setting in the menu GSM incoming groups. If the table does contain the CLIP, VoiceBlue waits for the end of the call from the GSM subscriber and then calls back to the subscriber in the GSM network.

• If the function Callback is not active or callback has already

been performed, a test is conducted for the permission of the service Mobility extension.

• If the service Mobility extension is permitted, the caller is

played the list of announcements Mess 1, Mess 2 and Mess3 (see chapter 6.4). The subscriber may then either activate or deactivate the function “Follow me” and “SMS at no answer” or transfer the selection to the subscriber in the VoIP network. After the connecting of a call it is possible, as a result of the function, to hold the call, forward it or terminate it as described in chapter 6.3.

2N - VoiceBlue Lite

• If the service mobility extension is not permitted, the table of

CLIP routings is searched. This contains records such as AutoCLIP routing and DynamicCLIP routing. If in the table the record AutoCLIP routing is found for the CLIP of the caller, the caller is directly routed to the branch the number of which is entered in the field autodial (see chapter 9.5). If the function AutoCLIP routing is not activated, or if the number of the caller is not included in the table of AutoCLIP routing, the handling of the incoming call continues with a search of the table DynamicCLIP routing. If the number of the caller is found in this table, the incoming call is directly routed to the corresponding branch. The function DynamicCLIP routing can be set in the menu GSM incoming groups (see chapter.

9.5).

• If even after this the incoming call is not dealt with, the gate

takes the call and either plays an announcement or dial tone to the caller. Then VoiceBlue Lite waits for the required number of numerals necessary for the making of a connection. The minimum and maximum number of numerals of the DTMF selection can be set in the menu GSM incoming calls.

• If VoiceBlue Lite does not receive the minimum required

number of numerals, and by the time designated by the parameter Delay when entering DTMF numerals further numerals doe not come from GSM, the call is rerouted to the operator in the same way as when the number of the branch called by the caller is not known.

• If the function of routing to the operator is not active, the

incoming call is refused.

Fig. 24 – Incoming Call Processing Procedure

7.6. DISA Message

If the DISA function is enabled and a welcome message recorded, this voice message is replayed to every incoming call whose number is not included in the CLIP routing table or dynamic CLIP routing table. After the message is replayed, the gateway waits for the first DTMF digit for a timeout defined in the GSM incoming groups – Tout for entering DTMF digits table. Having received the count of digits defined in GSM incoming groups – Min. digits in DTMF, the gateway activates the SIP Proxy connection. For more details on the gateway configuration refer to Subs. 9.5.

It is possible to program the DISA voice message into the gateway by following ways:

• Record DISA using configuration program (see. sub. 9.4)

• Record DISA using terminal and GSM phone

DISA Message Recording Using Terminal and GSM Phone

2N - VoiceBlue Lite

GSM groups assignment

Fig. 46 – Group Assigning Window

The users communicating through VoiceBlue Lite can be divided into user groups. You can define up to four mutually independent groups of outgoing and incoming calls that may be assigned arbitrarily to the GSM modules.

GSM outgoing groups

Fig. 47 – Outgoing Group Setting Window

The 2N - VoiceBlue Lite gateway allows you to work with four groups of outgoing calls. You can select different settings for each

2N - VoiceBlue Lite

of them with respect to establishing connections, count of called minutes and sent messages within a period. To set the company parameters use Default. The meanings of the card items are as follows:

• Roaming enabled for network – an international identification

code of the network for which roaming is enabled. It consists of two numbers:

• MCC – Mobile Country Code (Czech Republic -

230)

• MNC – Mobile Network Code (T-Mobile 01,

Eurotel 02, Oskar 03)

Thus, the T-Mobile International Identification

Code in Czech Republic is 23001.

To disable roaming leave this field blank.

• CLIR – This parameter defines whether or not the calling SIM

card telephone number shall be displayed to the called party. It is not recommended to present the telephone number of the SIM card inserted in the GSM module to the called party to avoid calling back problems. It is impossible for technical reasons to transmit telephone numbers of SIP terminals to a GSM network. One of the following parameters can be set for each GSM group:

• Factory – default settings of the GSM provider.

• Disable (CLIP on) – the SIM card telephone

number is transmitted to the GSM network. Contact your GSM provider for activation of this service if it is not supported automatically.

• Enable (CLIP off) – the SIM card telephone

number is not transmitted to the GSM network.

CAUTION! Some GSM providers do not support

this function, which might lead to rejection of an outgoing call.

• Max. number of called minutes – defines the maximum number

of minutes called within a moth through the given SIM card. This parameter is ignored if 0 is selected.

• SMS messages number– defines the maximum possible number

of SMS messages sent within a month from the given SIM card. This parameter is ignored if 0 is selected.

• Date of deleting stats – sets the day in a month on which the

statistic data on Max. number of called minutes and SMS messages number are deleted. This parameter is ignored if 0 is selected.

• Minimum length of call after connect – the length of the first

pulse after which pulses are counted according to the value included in the Precision of couting length of call parameter.

• Precision of couting length of call – the number of seconds per

pulse after the timeout defined in the Minimum length of call after connection parameter.

Example:

If, from the viewpoint of the GSM provider, a call shorter than 60s is billed as a 60s call, set the Minimum call length at 60s. If the GSM provider bills calls in seconds after the first 60s, set the Call length measurement accuracy at 1 s.

• Pseudo tariff – makes the GSM gateway generate tariff rate

pulses itself. The number defines how many pulses the gateway transmits per minute. The 0 value disables this function.

• Delay for CONNECT [s] – a delay before sending information

on a connected call after reception from the GSM network.

• Delay for ALERTING [s] – a delay before sending information

on ringing start.

• Disconnect call – the currently made call is disconnected in

cases included in a pull-down menu.

• Date of deleting stats in group – defines the day on which

statistic data on disconnected calls are deleted.

2N - VoiceBlue Lite

• Default delay for “SMS at no answer” – the service SMS at no

answer makes it possible to send information text messages to a user to the GSM network who at the time of a call from the VoIP network was not available. The wording of the text message can be edited in the field Text SMS (number = %N). In this field it is possible to designate how long the called party’s telephone should ring before the text message is sent. If the value “0” is set here, this function is not switched on.

• Text of the “SMS at no answer” - in this field it is possible to

edit the text which will be sent via a text message if the subscriber in the GSM network is unavailable.

• CLIP to GSM separator – if not empty, the character separates

Called party number and calling party number in the setup message to GSM

Example:

“CLIP to GSM separator” = “#”. If the user 999 in VoIP network dials +420123123123 to GSM, the VoiceBlue Lite dials +420123123123#999 to GSM network.

GSM incoming groups

Fig. 48 – Incoming Group Setting Window

The 2N - VoiceBlue Lite gateway allows you to work with four groups of incoming calls. You can select different settings for each of them with respect to establishing incoming calls. To set the default parameters use the Default button. The meanings of the card items are as follows:

• Mode – set the way the GSM gateway shall process incoming

calls from the GSM network:

• Reject incoming calls – all incoming calls from the GSM

network are rejected automatically.

• Ignore incoming calls – all incoming calls from the GSM

network are ignored automatically. The calling subscriber hears the ringing tone.

• Receive incoming calls + voice message – incoming calls

from the GSM network are received and, if defined so, the voice message is enabled for the incoming call while awaiting digits in DTMF.

2N - VoiceBlue Lite

• Receive incoming calls + dialtone – incoming GSM calls

are received and, if defined so, the simulated dial tone is enabled for the incoming call while awaiting digits in DTMF.

• CallBack after ring / Reject – in case the CLIP is

included in the CallBack table, a CallBack is made. The GSM gateway rejects the incoming call and makes an automatic CallBack.

• CallBack after ring / Ignore – in case the CLIP is

included in the CallBack table, a CallBack is made. The incoming call is ignored. If the calling subscriber does not hang up within the defined timeout (default = 10s), the CallBack function is ignored and the call is processed normally (refer to Subs. 7.5).

• Report to PC + voice message – the GSM gateway sends

information on an incoming call to a PC equipped with call routing software. The DTMF with a voice message may be enabled for the incoming call.

• Report to PC + dialtone – the GSM gateway sends

information on an incoming call to a PC equipped with call routing software. The DTMF with a simulated second dial tone may be enabled for the incoming call.

• Min. digits in DTMF – the minimum number of digits

required by the gateway in the DTMF.

• Max. digits in DTMF – the maximum number of digits

accepted by the gateway in the DTMF.

• Tout for entering DTMF digits [s] – a timeout during which

the GSM gateway waits for the first / another DTMF digit. If 0 is selected, the incoming call is connected automatically to the numbers included in the List of called numbers.

• Day of deleting incoming stats– defines a day in a month on

which statistical data on incoming calls are deleted. By setting this parameter at 0 you disable this function.

• Prefix before DISA – a digital prefix to precede the DTMF

automatically.

• CLIP – the '+' character from the CLIP shall be replaced

with a sequence of digits included in this field.

• CLIP to VoIP separator – if this field is not empty the

VoiceBlue Lite checks the CLIP from GSM whether contains character filled in this item. If the character is present in incoming CLIP VoiceBlue automatically dials number following this character to VoIP network.

Example:

“CLIP to VoIP separator” = “#”. If the CLIP from GSM is +420123123123#999 VoiceBlue Lite automatically dials 999 to VoIP network

• Time to keep CLIP in table [hours] – enter the time in hours

for how long should be the incoming calls routing record kept in the dynamic CLIP routing table. The routing records are added to the table automatically by establishing of outgoing call to the GSM network. Incoming calls are routed to the extension, which called the incoming CLIP as the last.

• Add record only for unconnected call – only unconnected

outgoing calls to the GSM records will be added to the dynamic CLIP routing table by selecting of this item.

• Delete record for connected answer – dynamic CLIP

routing record will be removed from the table when the originally called party in the GSM network calls back and is linked to the originally calling extension in the VoIP network.
