2N® OfficeRoute & Alcatel OXO connected via SIP trunk

2N® OfficeRoute has these parameters:

  • IP address 192.168.92.200
  • Listening port: 5060/5065
  • firmware version 2.3.11

Alcatel OXO parameters:

  • IP address 192.168.92.246
  • Incoming port: 5060
  • version 7.7.1

Settings of 2N® OfficeRoute

  1. Settings of SIP trunk for Listening port 5060

    1. Switching SIP proxy off

Default settings for SIP destination port in Alcatel OXO is 5060. 2N®OfficeRoute has port 5060 used by internal SIP proxy. That is why the SIP proxy has to be switched off for this case.

b. Creating a new SIP trunk

At menu Telephony services → Devices → SIP lines add a new line.
For a new SIP line:

    • Fill in SIP server address as IP address of Alcatel OXO, listen port 5060.
    1. Highlight or change a priority of codecs which should be used for this trunk.
    2. Uncheck Register with proxy checkbox
    3. Write some description of this trunk.

2. Settings of SIP trunk for Listening port 5065

In this case it is not necessary to switch SIP proxy off.

    1. Creating a new SIP trunk

      At menu Telephony services → Devices → SIP lines add a new line.

  • For a new SIP line - the recommendation as above.


3. Configuration of the LCR (Least Cost Routing)

At Telephony services → LCR disable all rules which are not routed into GSM.

Remove all rules from Telephony services – LCR – Normalization.

4. Incoming calls

Incoming calls can be routed to some DDI in OXO. For our case it is number 100 which will be dialed into our SIP trunk for all incoming calls. Create a new Operator rule in Telephony services → GSM routing → Operator.

Operator number is a number which will be dialed into chosen VoIP line for incoming call.



Assign the Operator service with GSM modules which should use this incoming rule. You can do it at Telephony services → GSM routing → GSM.

Create here a new rule for each GSM module and choose the service

Remove all normalization rules in GSM routing menu.
