    Hi,

    I'm new to 3CX but I managed to get a SIP trunk online. Incoming calls are working. However, when I try to call external numbers via the SIP trunk it doens't work.

    I call my SIP trunk provider and he told me that in the outgoing SIP header I need to a P-ASSERTED-Identity part where I need the put the DID I got from them.

    Can anyone tell me how I should do this? I know I have to change something with the parameter on the SIP trunk outbound parameters.

    Anyone can help me with this?


    3CX V10
    Intertel is the SIP provider
    Used the Generic Provider template
    I use the Softphone to test.

    You should do two things.
    First from your VoIP provider go to Outbound parameter and specify P-asserted Display Name SIP Field. Variable must be OutboudCallerID or Originator.... Click Add and Ok.

    Second goes to your extension parameter and in Others tab specify Outbound Caller ID - Here write your DID number.
