  • Parameters of 2N® Stargate:
    • IP address
    • Incoming port: 5060
    • Firmware:
  • Avaya equipment parameters:
    • Avaya Aura® Communication Manager 

      • version: R6.3 Build R016x. 

      • update:

    • Avaya Aura® System Manager 

      • version: R6.3 Build 

      • update 

    • Avaya Aura® Session Manager 

      • version: R6.3 Build 

      • IP address:


  • We have an IP network in which an Avaya solution (that consists of Communication Manager, System Manager, Session Manager and an Avaya G430 Gateway) and several SIP phones 
  • The Communication Manager is configured to communicate with 2N® Stargate via a DSS1 line on the Session Manager. 
  • The configuration would be as shown in the figure below. 


2N® Stargate settings


  1. Configuration of ISDN line

    Log in to web interface of your gateway and go to part Gateway configuration -> ISDN parameters.
    Under PRI mode selection choose mode PRI1 NT/M - PRI2 TE/S and click on Save icon in the bottom right corner
  2. Configuration of Port Modes

    Go to Gateway configuration -> Port modes.
    In this part of the configuration you can manage how incoming calls to the gateway will be handled for each interface. For GSM select Route all incoming calls to PRI2  and for ISDNPRI2 select mode Route all incoming calls to GSM and click on the Save icon in the bottom right corner.
  3. Configuration of the LCR (Least Cost Routing)

    The GSM operator has e.g. in our country prefix 6 and 7 with a nine digits in the number. The setting is below.

    You need to create LCR rule for defined prefixes. The GSM group defines a way for the outgoing call routing. An appropriate SIM card is selected based on the GSM groups assignment.

  4. Configuration of GSM outgoing groups

    You are able to set up different settings for each GSM group (CLIR, free minutes, virtual ring tone, roaming and others).

Incoming calls

For incoming calls you can define 2 groups with the different behavior and assign them to the GSM modules. The settings are similar with GSM groups assignment for outgoing calls.

In GSM incoming groups you can define the behavior for each GSM incoming group. Choose the mode to Reject, Ignore, Accept incoming calls or Callback.

You can define the list of called numbers which will be automatically dialed after DTMF dialing timeout if the customer does not press any button within the specified time. From the configuration you can see 10 seconds for DTMF dialing and after that the call will be routed to the extension 100 (if you set up SIP proxy (GSM->IP) in VoIP parameters).

Avaya Aura® Communication Manager settings

Configurations of the Communication Manager illustrated in this section were all performed using Communication Manager’s SAT administration interface. It is implied a working system is already in place including a Node for the Session manager and procr.

  1. Configure DS1 Circuit pack

    Avaya G430 and DS1 Circuit pack should be installed and configured as an E1 QSIG. If you don't know how to install or configure them, please contact your Avaya support. Picture bellow shows configuration of DS1 interface
  2. Configure of signaling-group

    A signalling group is required before a trunk-group can be configured. Use the add signaling-group command followed by next available signaling-group number to configure the following:

    • Group Type: Enter isdn-pri

    • Primary D-Channel: Enter 002V116 (this is the D-Channel associated with the DS1 Circuit Pack)
    • Trunk Group for Channel Selection: Enter 10 (This will be the trunk-group used in next section, section 3)
    • TSC Supplementary Service Protocol: Enter c (ETSI/DSS1)
  3. Configure Trunk group

    Use the add trunk-group command followed by next available Group number and configure the following:
    On Page 1

    • Group Type: Enter isdn

    • Group Name: Enter an informative name for the trunk i.e. DS1 Media G/W2
    • TAC: Enter a TAC number i.e. 710
    • Carrier Medium: Enter PRI/BRI
  4. Service Type: Enter public-ntwrk

    On page 2 enter:
  5. Supplementary Service Protocol: Enter c (ETSI/DSS1)
