Product description

1. Product description

OfceMaster Gate is a family of hardware controllers designed for Unied Communications applications. More

than 20 years of work experience by Ferrari electronic have own into the construction. Hereby the acquired skills

in the elds of active Fax/ISDN cards and networking Fax/SMS/voice mail solutions played a major part. The rm-

ware of the intelligent controllers has since then been signicantly extended and improved. Versatile scenarios are

supported:

Fax, SMS and voice mail services are supported for different operating systems when combined with the Unied

Messaging Software OfceMaster.

OfceMaster Gate can be used as a phone gateway to link ISDN-Private Branch Exchanges (PBX) or Trunks to

Microsoft Exchange Server 2007/2010/2013 UM, Ofce Communications Server 2007 and Microsoft Lync Server

2010/2013 in order to integrate their Unied Communications functionalities.

Those functionalities can be combined as well.

OfceMaster Gate is connected to the voice network via ISDN Basic Rate Interface (BRI) respectively ISDN

Primary Rate Interface (PRI) ports. An overview on all possible combinations can be found in the chart below.

OfceMaster Gate stainless steel box is always usable as Unied Messaging Controller or Gateway. There also is

a cheaper version of the larger PRI edition, solely for telephony (“UC”-edition). If need be those can be enhanced to

full functionality afterwards by purchasing the required licenses. All versions of the product can be set up at ISDN

main ports as well as on phone PBX’s.

By purchasing licenses OfceMaster Gate can be extended by multiple ports and functionalities.

Product description

1.1 OfﬁceMaster Gate: ISDN-Controller and Media gateway

Through the various scenarios of use different versions of OfceMaster Gate were developed. In this part Of-

ceMaster Gate products are described that function as independent Gateways respectively Controllers. (Apart from

that there are versions of boards that are described later on.)

No additional software needs to be loaded into the box. All of the linux based rmware is placed in the ash drive

and loaded into the RAM for execution when booted.

Operated on a PBX (resp. Point-to-Point protocol), Ofce Master Gate acts similar to a PBX, meaning it sup-

ports direct inward addressing and allows automatic assigning of calls (fax, SMS, voice mail and phone) depending

on different dial through numbers.

OfceMaster Gate complies with the specications dened by the ITU for fax group 3. Apart from the compul-

sory transmission with 4800 and 2400 bps, 9600 resp. 7200 and 14400 resp. 12000 bps are possible too.

For fax transmission dened one and two dimensional modes of compression MH, MR and MMR as well as the

error correction mode (ECM) are supported.

Alternatively or simultaneously OfceMaster Gate can be used as a media gateway for Microsoft Exchange UM,

OCS 2007 (incl. R2) as well as for Microsoft Lync Server 2010.

1.1.1 OfﬁceMaster Gate stainless steel box for Basic Rate Interface (BRI)

The BRI editions of OfceMaster Gate run a powerful 32-bit microprocessor. No additional software needs to be

loaded into the box. All of the linux based rmware is placed in the ash drive and loaded into the RAM for execu-

tion when booted. Because of the autonomy of the system, the UM server is supported by the controller, keeping

the strain to a minimum. No settings via jumper are needed for the hardware, making installing, implementing and

if needed replacing very simple

Image 1.1: OfceMaster Gate BRI stainless steel box

www.ferrari-electronic.com

Product description

OfceMaster Gate for BRI can use both channels of a line simultaneously. The controller supports Euro-ISDN

(EDSS1) and works on a multiple device line as well as on the system line. OfceMaster Gate is also usable for

subsystems and supports some performance characteristics of the TK system protocol QSIG (Q-Interface Signaling

Protocol).

OfceMaster Gate can either be plugged in with the included power adapter or, if supported in the network ac-

cording to 802.3af, be supplied via Power over Ethernet (PoE).

Note!▼ Are both power supplies enabled, the power adapter is used. Hereby it is strongly

recommended to ﬁrst plug in the mains power supply and after that the Ethernet connection. A switch of power supplies is to be avoided while booting.

1.1.2 OfﬁceMaster Gate for Primary Rate Interface (PRI)

OfceMaster Gate for PRI is shipped in a 19“ case. This case holds a PC Mainboard. The PRI adapter is included

in form of a PCIe board.

Image 1.2: OfceMaster Gate 19“ version

OfceMaster Gate for PRI (19“) can use all 30 to 60 (respectively 120) channels of a line simultaneously. The

controller supports Euro-ISDN (EDSS1) as well as important features of the TK system protocol QSIG (Q-Interface

Signaling Protocol).

1.1.3 OfﬁceMaster Gate UC

For the use as a Media gateway for Microsoft Exchange 2007/2010/2013, Microsoft Ofce Communications

Server 2007 R2 and Microsoft Lync Server 2010/2013, specic versions of OfceMaster Gate are available, which

are not supported on delivery.

By subsequently adding additional licences, channels for the selection of OfceMaster Software for fax, voice

mail and SMS can be enabled step by step.

Product description

1.2 OfﬁceMaster Survivable Branch Appliance (SBA)

With Microsoft Ofce Communications Server (2007/2007 R2) it was for the rst time possible to use a central

installed OCS at a remote branch. This cost-efcient solution had the drawback that in case of a WAN failure the

whole telephony at that specic branch would fail.

Image 1.3: Solution scenario with OfceMaster SBA

Microsoft Lync Server 2010 was the rst version that supported remote site telephony even on WAN outages.

Microsoft has dened an appliance type of products containing all functions needed for telephony in a branch of-

ces; therefore called “Survivable Branch Appliance” (SBA). The same holds true for the new Lync Server 2013

which also offers a compatible SBA product.

„OfceMaster SBA“ is based on high quality industry grade server hardware which runs Windows Server 2008

R2 together with Microsoft branch ofce components like Registrar and Mediation Server.

A separate PCI-Express card contains the complete media gateway which supports different types of ISDN con-

nections – four basic rate interfaces (BRI) supporting 8 ports and up to 60 channels of E1/T1 primary rate (PRI)

connections. Four analog FXS ports are available through an additional low prole PCIe card. If more ports are

needed, separate external devices can be added. In addition, support for SIP trunks and legacy telephony devices are

available as well. The gateway board is recognized by the hosting server machine as a standard network interface

card – all gateway functions are completely off-loaded from the main CPU.

www.ferrari-electronic.com

Product description

The same hardware can also be used as a Basic Hybrid Gateway for Microsoft Ofce Communications Server

2007 R2 which can be upgraded to a Survivable Branch Appliance later.

1.1 Functionality and Connection

1.2.1 One product – multiple possible applications

For the use as gateway for Exchange 2007/2010/2013 / Ofce Communications Server 2007 (OCS/OCS R2) /

Microsoft Lync Server 2010 as well as when used as Unied Messaging Controller, it is necessary to obtain certain

information about the caller. The called number and potential carried out call forwarding need to be evaluated in

order to nd the appropriate way of processing the call.

When used as Gateway and Unied Messaging Controller at the same time, it is to be decided whether an incom-

ing call is meant for Exchange, OCS, Lync Server or the OfceMaster Messaging Server. This calling information

is provided on each call via the ISDN-D-Channel-Protocol. Depending on the different telephone system, the depic-

tion can however vary. To ensure uniform depiction for the further use, an extremely capable call number analysis

and call number correction has been integrated into OfceMaster Gate.

Inherently, OfceMaster Gate is installed on a telephone system or a trunk line via ISDN and is able to process

incoming calls. For those calls OfceMaster Gate decides whether or not to take the call, upon the routing (by which

instance, for example Exchange 2007/2010, OCS, Lync Server or OfceMaster, the call is to be handled) and upon

the replacing or respectively modifying of call information (which call information does the processing instance

expect at what point).

Through additional functions provided by OfceMaster Gate for Microsoft UM/UC solutions (Exchange, OCS,

Lync) and through the double functionality as controller for the Unied Messaging System OfceMaster, relatively

complex settings for calling numbers can be required. The conguration of usual cases of application is therefore

possible via a very simple dialog, while more complex settings can be made via exible rule-table in the advanced

mode. It is possible to switch between advanced and simplied mode. In the simplied mode created congurations

are internally converted into rules and can be looked at in the advanced mode.

1.2.2 Connection to Exchange 2007/2010/2013 UM

In the following, the processing of incoming calls in Exchange UM is described. The phone number of a par-

ticipant, who has been activated for Exchange Unied Messaging, is saved in the Active Directory as a EUM-

(Exchange Unied Messaging) address. For incoming calls, the participant is identied via this phone number. Has

the participant set up call forwarding to the so called Pilot-ID of the Exchange UM on his connection, the incoming

call is redirected. The calling number of the participant is in that case provided as Redirecting Number (Redirected

Number; in SIP-Protocol: Diversion Header). With this information, Exchange determines the partaker and starts to

play the welcome message to the called to, if applicable, record a voice mail.

Is the incoming call a fax, OfceMaster Gate will automatically note this and in interaction with Exchange ac-

tivate the fax function.

www.ferrari-electronic.com

Product description

The welcome message will also be played, should the participant call his own redirected line from a different

phone, for example his mobile phone. Through the appropriate key input („*“-key), Exchange can be set into the

remote query mode where the called will be asked to identify himself via his PIN.

No redirecting number is available should the participant, for remote query purposes, directly call the Pilot-ID

of Exchange UM, because no redirecting occurs. In this case Exchange will ask for the Voicebox-Number (meaning

the redirecting path) of the participant for identication and afterwards for the PIN for authentication. Therefore, the

fax function of the calling number of the participant will only occur when the connection is redirected. OfceMas-

ter Gate provides ways to work around this signicant limitation and enable the fax function permanently without

having to keep a separate dial-through number as EUM ¬address for fax. Detailed information for this can be found

under „conguration“.

1.2.3 Use as media gateway for Lync Server 2013/2010

An important use of OfceMaster Gate is as phone gateway for Microsoft‘s UC-systems. The Gateways passed

the necessary certication tests for those systems and can therefore be used restrictive free - both as stand-alone

Gateways and in combination with the OfceMaster software, using the hardware and ISDN-ports together for all

communication services (Fax, SMS, voice mail and telecommunication).

The communication can optionally take place encrypted (SIP/TCP, RTP) or not encrypted (SIP/TLS, SRTP).

Located left and right below the BRI port of OfceMaster Gate are two LED‘s. These are triggered by the rm-

ware of the controller:

• The right hand side LED is triggered, when layer 1 of the ISDN protocol is activated.

• The left hand side is triggered, when the in-build ISDN terminating resistors are triggered via the congura-

tion program.

Note!▼ In older versions of the hardware, the left hand side LED is triggered, when the

terminating is turned off! In all cases though, the settings in the conﬁguration program apply.

Should an additional ISDN device be connected to the same BRI as OfceMaster Gate it is mandatory that the

ISDN port is declared as a multiple-device-port (point-to-multi point). When used in parallel connection, Ofce-

Master Gate and others connected to this line need differing MSN (Multiple Subscriber Number) to be assigned to

them. Is the ISDN line in point-to-point mode, no parallel connection is possible.

2.2 Network Integration

OfceMaster Gate is addressed by the OfceMaster Server-Software or, if used as media gateway, via the net-

work. The Server-Software in this case is the component OMCUMS of the messaging server.

OfceMaster Gate and OMCUMS communicate via TCP/IP. For this, they need to know each others IP addresses.

www.ferrari-electronic.com

Installation

If used as media gateway, the communication with Microsoft servers occurs in the same way.

To make this possible, every OfceMaster Gate is in need of a tting network address. Possible ways of ensuring

this:

with DHCP server

OfceMaster Gate in delivery condition (standard, even after resetting) receives its IP¬ conguration from the

in the network existing DHCP server. Via a DHCP server, IP¬ addresses and the Domain Name Server (DNS) are

assigned to computers in the network.

In OMCUMS, the IP-address of OfceMaster Gate is manually declared.

The uniqueness of the IP-addresses is ensured and an address conict ruled out, because only one side requires

a manual entry.

without DHCP server

Is no DHCP server existing in the LAN or is the existing DHCP server not assigning an address to OfceMaster

Gate (because he for example is out of valid addresses), then OfceMaster Gate will after a while automatically

assign itself a private address (a so called Zeroconf-Address, also called APIPA-method). This address allows the

activation of the build-in network interface, to ensure at least the availability via UDP broadcast. For the normal use

however, in this case a static address will have to be assigned.

The program OfceMaster Gate Conguration (OfceMasterGateCong.exe) is used to nd OfceMaster Gate

in the network. By clicking the correct button, sub network wide search for OfceMaster Gate is started via UDP

broadcast. Sub network in this case is the physical network, in which the computer with the IP conguration pro-

gram is integrated. This sub network is usually restricted by network routers, for example rewalls, that do not

redirect the UDP broadcast.

In order to assign an address to OfceMaster Gate, Ofce Master Software either uses an distinct IP address or

the resolved name.

If OfceMaster Gate, as described above, is used as DHCP client, than it should be ensured, that OfceMaster

Gate is available under the same IP address after reboots, so that the Server-Software can continue working properly.

Possible ways of ensuring this:

At the DHCP server, an IP address is reserved for the MAC address of OfceMaster Gate. This way, OfceMas-

ter Gate receives the same IP address after every reboot.

In the OfceMaster Server Software, instead of the IP address, the resolved name is congured. Now when the

DHCP server automatically refreshes the DNS server, OfceMaster Gate will still be reachable by the Server Soft-

ware, even after having been assigned a different IP address.

Installation

2.3.3 Analog Card – 4 Port (FXS)

Four analog ports are contained on a separate low-prole PCI-Express Card connected to the main gateway

board using a at ribbon cable.

Image 2.3: Analog Card

The cable transports audio signals through a TDM bus as well as separate control information. High quality

faxing is possible since no VoIP technology is involved between PSTN and FXS ports.

2.3.4 ISDN and Analog Interfaces

Positions of analog and digital interface connectors are shown in this picture (rear view):

Image 2.4: Interfaces of the OfceMaster SBA

For BRI ports a separate Y-cable must be used if more than two BRI lines are needed.

Note!▼ Never use PRI 2 without PRI 1 – if only one PRI interface is connected always use PRI

1, otherwise clock synchronization will not work!

2.4 Recovery

2.4.1 Survivable Branch Appliance

Use of the Recovery USB Stick

The SBA system software can be reset to factory settings at any time by using the USB recovery stick.

Please follow these steps:

1. Connect the SBA device to Keyboard, Monitor and Mouse, either physically, using KVM or through tools

like HP ILO

2. Plug the USB stick into the front USB port

3. Power up SBA, it will automatically boot from the USB

4. At the end (message: press any key to shutdown computer) press a key

5. Remove USB stick

6. Power up SBA

7. Set the local Administrator password to OfceMaster!

8. Check network interface conguration (see below)

9. Open a cmd console and enter the following commands: %systemroot%\system32\inetsrv\appcmd.exe set

APPPOOL omsba_admin_pool -processModel.userName:ofmadmin %systemroot%\system32\inetsrv\appc-

md.exe set APPPOOL omsba_admin_pool -processModel.password:Sefte25AuTib

10. Now the deployment Web UI is ready for use

www.ferrari-electronic.com

Installation

Note!▼ When a SBA is shipped, the serial number of the embedded gateway board is al-

ready preconﬁgured. After using the recovery image, the gateway serial number will be queried later by the Web UI during deployment. The serial number of the gateway board can be found on a card, which can be pulled out at the front side:

Image 2.6: In this example the number to be entered is 259 (last 5 digits without leading zeros). (On some models, the number may be hand-

written and may contain the serial number only, without the prex, e.g. 234).

Check of the network interface conﬁguration

During deployment of the Windows image via USB stick, the desired network conguration is automatically

established:

Image 2.7: Network bridge on the SBA

www.ferrari-electronic.com

Installation

This is the standard conguration, where the gateway board (can be identied as Realtek Controller) is bridged

with the LAN port (Local Area Connection 2), which is used for connecting to a switch. The unused second LAN

port (Local Area Connection 3) is disabled. In some situations (e.g. due to different BIOS revisions), the physical

LAN adapters have different internal id’s, meaning that the restored conguration must be corrected manually.

Image 2.8: Example of a network conguration that needs to be corrected

End of Example»

The necessary changes in this case are:

• Right click on Network Bridge – Properties

• Make Local Area Connection 4 (LAN Port) and Local Area Connection 5 (Gateway board) the only members

of the bridge

• Disable Local Area Connection 6

Now all network conguration settings should be made on the network bridge only. The SBA is ready for de-

ployment after a nal reboot.

2.5 Stainless steel box - Restore to factory settings

At the front as well as at the back of the case of the version for BRI‘s, there is one micro button each:

Table 2.3: Button on the stainless steel box

Micro button Resulting function Description

Micro button front Hardware Reset reboot system

Micro button rear Software Reset reset conguration parameters Function is deactivated one minute after

booting is completed (signaled by blinking diodes)

Reinstalling the software

Should OfceMaster Gate (in the stainless steel version with 4 BRI) stop working properly, a recovery can be

done with newer versions of the product (February 2011 onwards, distinguishable by the USB port on the side). To

do this, the Gateway needs to be disconnected from the power supply and the recovery stick from the bottom of the

case has to be plugged into the USB port. Afterwards, reconnect the Gateway to the power supply. Turn off the Gate-

way after roughly 30mins and remove the stick. When used afterwards, make sure a backup of the conguration is

loaded and, if needed, an update of the rmware is made.

Conﬁguration

3. Conﬁguration

The products of the OfceMaster Gate family use a coherent rmware as a base, which operates the depending

on hardware available ports

Because of the coherent base and the therefore identical conguration-ports, every OfceMaster Gate of the 3rd

generation can be operated with the same user interface.

Even though the essential congurations of OfceMaster Gate are identical, when installing the SBA and the

Hybrid Gate, additional steps of conguration are necessary.

3.1 OfﬁceMaster Gate Basic Settings

If OfceMaster Gate is used solely in combination with the Unied Messaging Software OfceMaster, then the

conguration is made via the integrated administration program (see manual OfceMaster Administration). The

gateway function of OfceMaster Gate can be enabled if needed.

For the activation and conguration of the gateway function, an administration program (OmGateCong.exe,

installed via SetupOfceMasterGateCong.exe) is provided, which can be installed at any work space. A mixed use

as gateway and Unied Messaging Controller for OfceMaster can be set up with this program. The main dialog

will pop up after starting the conguration program:

Image 3.1: Connected OfceMaster Gate

Some of the elements will only become active, once a connection to the controller is provided (see next section).

Note!▼ The language can be changed between German and English in the help menu.

www.ferrari-electronic.de

Conﬁguration

3.1.1 Connecting to OfﬁceMaster Gate

After the start of OfceMaster Gate conguration, the connection to OfceMaster Gate has to be established.

Via File > Search or by pressing the search symbol, name, IP address, version and number of channels of the found

controllers are listed:

Image 3.2: Available OfceMaster Gate in the Network

In this list, the preferred entry is selected and conrmed by pressing OK. A login dialog will then appear:

Image 3.3: Login dialog

This dialog can also be accessed directly via

File > Connect

, in order to enter the IP address of OfceMaster

Gate manually. For authentication purposes, a password is required.

Note!▼ The standard password on delivery is „omc“.

3.1.2 Network conﬁguration

In order to change the network settings (for example IP address) the button

change IP address...

has to be

pressed. Alternatively the same can be achieved by going via

Edit > change IP address

. Depending on the struc-

ture of the used network, IPv4 and/or IPv6 addresses can be declared.

www.ferrari-electronic.de

Conﬁguration

Image 3.4: Network settings

Note!▼ The conﬁguration program communicates through UDP-Broadcasts via the port

3216. With OfﬁceMaster this also works through interposed switches, while routers usually will not forward the Broadcast-Messages.

The mode activated on shipment of OfceMaster Gate is DHCP-Client. Possible modes of operation are DH-

CP-Server (IPv4 only), DHCP-Client and static.

DHCP-Server (IPv4)

The DHCP-Server mode is only useful for OfceMaster Gate, if OfceMaster Gate is connected to a host com-

puters network card via cross cable and when this network card is run in DHCP-Client mode.

DHCP-Client (IPv4)

This is the standard setting of OfceMaster Gate. In this mode of operation it is assumed, that there is a DH-

CP-Server existent in the network, which will assign the controller with an IP address and every other required val-

ue. OfceMaster Gate registers itself under the name that is shown in the rst slot of the IP conguration program.

If the DHCP-Server automatically initiates a DNS refresh then OfceMaster Gate can be contacted directly under

that name in the network.

Static (IPv4)

Is the network run without a DHCP-Server then OfceMaster Gate needs to get a static IP address, a subnetwork

mask, a gateway address (optional) as well as the address(es) of the DNS Server(s) assigned to it.

A Domain Server Name (DNS) has to be assigned, when the target systems are addressed via FQDN (Fully

Qualied Domain Name). Because these can, on occasion, malfunction, a alternative DNS should be congured as

DNS2.

www.ferrari-electronic.de

Conﬁguration

Automatically

With this setting, an automatically assigned IPv6 address will be used.

Static IPv6 Address

Similar to IPv4, with IPv6 as well the declaring of a static IP address is possible. Are the target systems contacted

via FQDN (Fully Qualied Domain Name), at least on Domain Name Server (DNS) has to be declared. Since one

DNS server can always falter, and additional one should be congured as DNS2.

Proxy

A Proxy has to be set under the tab „Proxy“, should a connection in the network only possible via a Proxy.

► Number of Channels to use

In the following it is decided, whether the existing B-Channels are to be used completely for in-and outgoing connections or if, for example outgoing calls are only allowed to use a certain percentage, so that there are free channels for incoming calls under any given circumstances.

-Button

By pressing the [...] button a dialog is opened, that enables the user to dene, which B-Channels can be used at all, for example with „halved“ PRI ports. This „incomplete“ pin assignment is relatively common outside of Germany.

► ISDN Connection

The different types of connection are Point-to-Multi point and Point-to-Point.

► Point-to-Point (DID)

Point-to-Point only supports one ISDN device, usually a telephone system or a media gateway. A Point-toPoint connection is assigned a complete dial through numbers area.

► Point-to-Multi point (MSN)

Point-to-Multi point connection only supports a limited number of receiver call numbers (usually 3 to 10), so called MSN (Multiple Subscriber Number). Hereby multiple ISDN devices (Phone 1, Phone 2, Fax) can be connected.

► QSIG

Additional to Euro-ISDN or DSS1, there is also QSIG. This is an ISDN protocol that is sometimes used by a selective number of telephone systems. Via QSIG, additional information like the callers name can be transmitted.

► Onboard Termination

OfceMaster Gate for BRI allows the addition of ISDN terminating resistors, which should usually be existent in the ISDN socket. By default, these internal terminating resistors are deactivated.

A LED can be found on the left side below the ISDN socket of OfceMaster Gate (stainless steel edition). If this one is lid, then the rmware enabled the terminating resistors according the conguration settings.

Note!▼ Usage without terminating resistors can lead to ISDN errors. In older versions of

the hardware, this LED will be triggered if the terminating resistors are off! The settings in the conﬁguration program are in effect in any way

► NT Mode (Network Termination)

This option is usually used in order to place the gateway between the telephone network and the PBX. Towards the telephone network the gateway acts like a PBX (as TE, meaning Terminal Equipment), while towards the PBX it acts similar to the trunk.

www.ferrari-electronic.de

Conﬁguration

Note!▼ This only works in Point-to-Point mode. Common terminals will not be usable on

this line as such devices usually run in Point-to-Multi point mode. Additionally, a cross cable needs to be used for the connection with the PBX.

► [...]-Button – Advanced Connection Parameter

► Dial Timeout

When simulating an external line, numbers of any random length will be communicated by the telephone system. In order to decide, which calls are supposed to be redirected outward, a timeout is set, after which no more digits are to be expected. This timeout usually happens after 3-5 seconds.

► Caller Name Display Mode

Is QSIG activated in the ISDN protocol, caller names can be transmitted for incoming and outgoing calls. Since this is based on different protocol versions depending on the system, testing is the only way to nd the right setting.

► No L2 auto-activation (Point-to-Point Options)

With a Point-to-Point connection, the gateway will try to keep active the layers 1 and 2 in the D-Channel at all times. This behavior can be deactivated here.

► ISDN Type of Number, Mapping from/to E.164

Type of Number is usually dened in ISDN in order to dene information about the type of call. Internally (for

example Lync or OfceMaster Suite) calls are usually in E.164 format, meaning that they need to be adjusted properly.

► International

With calls from ISDN, the congured „call number“ (for example „+“) is fronted when the Type of Number (TON) is set to „international“.

For outbound calls, meaning to ISDN, the TON is recognized via the congured call number and the call number removed.

► National

National numbers are treated equivalently to international numbers.

► Subscriber

The local connection is entered under Subscriber.

With settings as seen in Image 4.6, the inbound signal from Table 4.1 is converted into an E.164 number. Af-

terwards, OfceMaster Gate’s set of rules are applied for further customization of the phone numbers and for the

delivery towards the appropriate destination as described in the following (4.1.4).

► More – Settings for multiple channels

OfceMaster Gate is available in versions with multiple ISDN channels. The conguration program supports this by letting the user congure channels individually. Alternatively, all channels can be dened to copy the settings of the rst channel. This can be activated via the button

3.1.4 Calls from ISDN

For the selection of the target gateway, a separate tab is available in the advanced mode. In this tab, targets are

chosen depending on the calling number and reshaping can be done.

In the tab

Calls from ISDN

a list of the congured rules is shown:

Image 3.7: Rules for inbound calls

In this dialog you can add, delete, process and change the sequence of these rules. To edit, delete or move a rule,

click on it with the mouse button to select it and then select the action you require.

Additional options are offered by the context menu, which is opened by right clicking an entry:

Image 3.8: Context menu for Gateway rules

Many of these functions can be used with multiple rules at the same time. For this, the rules need to be selected

via multi-marking (Shift resp. Ctrl + left mouse button).

For when a new rule is created, the elds are set up to select any number and to remain unchanged after substi-

tution (substitution by itself.)
