2N® Voice Blue Next settings

  1. SIP trunk interconnection

    For the setting of the trunk between the 2N® VoiceBlue Next and your PBX you need to configure SIP proxy (GSM→IP) for GSM incoming calls. SIP proxy (IP→GSM) is designed to secure communication with traffic from your CCM only. You can specify the IP address and port from which SIP packets will be accepted.

    In case you leave there 0.0.0.0 it will be open for all traffic.

  2. Configuration of the LCR (Least Cost Routing)

    The GSM operator has e.g. in our country prefix 6 and 7 with nine digits in a 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.

  3. 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)

  4. 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 to your 3CX PBX (if you set up SIP proxy (GSM->IP) in VoIP parameters).
