1.2 Safety Precautions

It is prohibited to use any transmitters, including the UMTS/GSM devices, in areas where explosives are used, such as quarries. It is prohibited to use the GSM gateways at petrol stations where mobile telephones are also prohibited. GSM phones may affect sensitive life–saving devices in medical centres. Therefore, it is forbidden to use GSM/UMTS devices, including the GSM gateways, in such facilities. In general, any prohibition regarding mobile phones based on RF energy radiation applies to GSM/UMTS devices too. If necessary, the GSM gateways may be installed at a safe distance from the prohibited area and connected with the original place through an Ethernet cable. Although GSM gateways are not intended for cars or aeroplanes, all relevant prohibitions and regulations regarding mobile phones apply to them too.

2.4 IP Voice Transmission

Speech Encoding Methods

Voice transmission is strictly separated from signalling in VoIP networks. Modern VoIP networks mostly use the RTP (Realtime Transport Protocol) for voice transmission. The purpose of the RTP is only to transmit data (voice) from a source to a destination at real time. Codecs are used to save the channel data capacity. Codecs process the voice signal using variable algorithms to minimise the volume of user data. The degree of compression used by the codec affects the quality of voice transmission. Thus, the better voice transmission is required, the wider data range (the higher transmission rate) is needed. The MOS (Mean Opinion Score) scale is used for rating voice transmission quality, where 1 means the worst and 5 the best quality. For a survey of

the codecs supported by refer to the table below.2N VoiceBlue MAX

Codecs supported

Standard Algorithm Transmission rate [kbps] MOS

G.711a PCM 64 4.1

G.711u PCM 64 4.1

G.729 CS–ACELP 8 3.92

For , quadruple the above mentioned rates (two fully duplex 2N VoiceBlue MAX

calls) and add the TCP and IP header transmission rate to the result to get the resultant transmission rate.

It is important to keep both a stable appropriate transmission rate during connection and a small and identical transmission time per data packet in order to maintain a high–quality voice transmission.

G.711 – this codec is used in digital telephone networks. The PCM (Pulse Code Modulation) is used for voice signal encoding. The sampled signal is encoded in 12 bits and then compressed using a non–linear scheme into the resultant 8 bits. Europe uses the A–law compression system while North America and Japan obey the µ–law. The resultant data flow is 64 kbps. G.729 – this codec uses the CS–ACELP (Conjugate–Structure Algebraic–Code–Excited Linear–Prediction) algorithm with the resultant transmission rate of 8 kbps. The speech signal is split into blocks of 10 ms each. The parameters of these blocks are then inserted in frames of the size of 10 bytes. 2–byte frames are generated for noise transmission.

During call set–up, a codec is selected automatically for voice transmission. 2N

supports the codecs included in the table above. The type of codec toVoiceBlue MAX

be used depends on your VoIP network (individual devices) and your 2N VoiceBlue

configuration. is designed primarily for VoIP corporateMAX 2N VoiceBlue MAX

networks and tries to meet the opponent's codec requirements. If a codec is requested that is incompatible with , the call will be rejected.2N VoiceBlue MAX

The SIP and ITU–T H.323 recommended protocols are mostly used for connection establishing, maintaining and cancelling. uses the (Session2N VoiceBlue MAX

SIP

Initiation Protocol) signalling.

212N TELEKOMUNIKACE a.s., www.2n.cz

Tip

In the case of separated direct connection of your SIP Proxy and , use the G.711 codec to achieve a 2N VoiceBlue MAX

high voice quality.

SIP Components

The following components are involved in the SIP message exchange:

UAC (User Agent Client) – the terminal device client, which initiates SIP signalling. UAS (User Agent Server) – the terminal device server, which responds to SIP signalling from the UAC. UA (User Agent) – a SIP network terminal (SIP phones, gateways to other networks, etc.), which contains the UAC and UAS. Proxy server – receives connection requests from the UA and transfers them to the next Proxy server if the given station is not under it administration. Redirect server – receives connection requests, but, instead of sending them to the called line, sends them back to the requesting device asking for where to route the request. Location server – receives registration requests from the UA and updates the terminal database accordingly.

All the server components (Proxy, Redirect, Location) are mostly on one physical device called Proxy server, which is responsible for keeping a client database and connection establishing, maintaining and terminating, as well as call routing.

The VoIP–GSM gateway acts as a UA in any case (has the same 2N VoiceBlue MAX

functions as a VoIP phone), i.e. receives call set–up requirements and, on the basis of its inner LCR table, routes calls to GSM networks.

None of the SIP–defined server components are integrated in the 2N VoiceBlue

gateway.MAX

SIP Signalling Messages

Below is a list of messages sent via the SIP:

INVITE – connection set–up request; ACK – INVITE confirmation by the final message addressee; BYE – connection termination; CANCEL – failed connection cancellation; REGISTER – UA registration with the SIP Proxy; OPTIONS – server capability query.

The answers to the SIP messages are numerically coded as the case is with the http protocol. Below are the most important ones:

1XX – information messages (100 – trying, 180 – ringing, 183 – progress); 2XX – successful request completion (200 – OK); 3XX – request forwarding needed (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).

2.5 2N® VoiceBlue MAX Connection to VoIP

Since communicates using the SIP only, this subsection outlines2N VoiceBlue MAX

solutions for its interconnection with networks working with the H.323 signalling protocols. can be used either in the Point–to–Point or2N VoiceBlue MAX

Point–to–Multipoint mode with the SIP Proxy server.

SIP / H.323 Interconnection

SIP–based devices cannot communicate with H.323.supporting devices directly, but through a SIP/H.323 gateway. This gateway transfers signalling messages from/to the protocols. Using the RTP for multimedia data transmission, the SIP and H.323 protocols can go on communicating directly when the SIP/H.323 gateway connection is

established. Thus, the SIP/H.323 gateway helps integrate into2N VoiceBlue MAX

the existing H.323 environment.

Point–to–Point Configuration

2N VoiceBlue MAX® can communicate with just one SIP VoIP phone or device (a VoIP

gateway, e.g.) in the PTP (Point–to–Point) mode. The IP address of the opposite party is always selected as the Proxy server IP address in for this2N VoiceBlue MAX

mode. The PTP configuration is often used for testing purposes before2N VoiceBlue MAX

implementation into the VoIP network. Refer to the figure below for the PTP scheme.

Tip

If you set the incoming SIP Proxy IP address to '0.0.0.0' in the

All calls outbound to GSM are routed to the 2N VoiceBlue MAX® gateway in the Point–to–Point mode that uses 2N VoiceBlue MAX®.

Point–to–Multipoint Configuration

Point–to–Multipoint is a classical scheme of a distributed VoIP network with one or more SIP Proxy servers (VoIP gateway). The SIP Proxy server is a software PBX (or a standard PBX extended with VoIP services), which is responsible for all VoIP signalling.

Multiple source devices (VoIP phones, e.g.) and multiple target devices ( 2N

, e.g.) can be used in this mode. An internal routing algorithm (Least VoiceBlue MAX

Cost Router, LCR) of your SIP Proxy is used for routing outgoing GSM and other calls in this mode. Calls to GSM networks can be routed via the gateway2N VoiceBlue MAX

s. All SIP signalling is governed by the SIP Proxy server and the subsequent voice stream is based on the Point–to–Point RTP.

Install the GSM gateway as instructed in Before the first start, removeSubs. 2.3. the SIM cards, or insert the SIM cards with the PIN request disable. Connect the GSM gateway to the Ethernet network to enable connection to the address mentioned in from the configuration terminal. If the gatewaySubs. 2.2 default IP address is not suitable for your Ethernet installation, reset the IP address as follows:

Disconnect the configuration terminal from the Ethernet network. Disconnect the GSM gateway from the Ethernet network. Prepare the Ethernet switches, or an Ethernet crossed cable. With the Ethernet crossed cable, interconnect the configuration terminal with the GSM gateway directly. With the Ethernet switch, connect the configuration terminal and GSM gateway to the pre–prepared Ethernet switch. We do not recommend connecting any other equipment. Change the Ethernet IP setting in the configuration terminal, e.g.: IP=192.168.1.200, Net Mask: 255.255.255.0. Open your web browser and enter the GSM gateway IP address. Enter the factory login data. Change the required settings in the Gateway configuration, Ethernet

menu and store the data into the GSM gateway.configuration Connect the GSM gateway to a standard Ethernet network. Restore the configuration terminal IP setting and connect the configuration terminal to a standard Ethernet network.

Enter the new GSM gateway IP address to get connected to the web interface. Enter the current time and date in the menu forGateway control, Date/Time the GSM gateway. Make sure that the item is in the Licence status unlocked Gateway control,

menu. If not, your GSM gateway does not contain theFirmware/Licence licence. Contact your dealer for the licence key. Set the correct PIN value in the Gateway configuration, System parameters menu. The value must comply with the SIM card PIN value. Set new login data in the menu.Gateway configuration, Login configuration Switch the GSM gateway off and insert the SIM cards. Connect an antenna to the GSM gateway and switch it on. The GSM gateway contains the factory configuration settings that enable outgoing calls without additional settings. Now enter the IP address equal to the GSM gateway IP address on your SIP Proxy or IP terminal.

From now on, will be ready to receive VoIP–SIP calls and route2N VoiceBlue MAX

them to GSM/UMTS networks. If all the GSM modules are occupied, or logged out, the GSM gateway will reject all VoIP–IP and GSM/UMTS calls. Should you get in troubles, follow the steps below please:
