Register Trixbox with Netcall.pt for incoming and outgoing calls

Go to freePBX à Trunks and create a SIP trunk.

Then trunk settings are:

• General Setting
  • Outbound Caller ID: "YOUR NAME" <YOUR NUMBER>. Type exactly with "" and <>
• Outgoing Dial Rulles
  • Dial Rules: I defined a simple rule XXXXXXXXX. In Portugal the common telephone numbers have 9 digits. This is only for a testing environment. In real world this has to be tuned.
• Outgoing Settings
  • Trunk Name: Netcall (or whatever you want)
  • Peer Details:

    allow=peex&ulaw&alaw&g726&gsm
    

    auth=YOURNUMBER:YOURPASSWORD@sip.netcall.pt
    

    call-limit=10
    

    canreinvite=no
    

    disallow=all
    

    dtmfmode=rfc2833
    

    fromdomain=sip.netcall.pt
    

    fromuser=YOURNUMBER
    

    host=sip.netcall.pt
    

    insecure=very
    

    nat=never
    

    qualify=no
    

    secret=YOURPASSWORD
    

    type=friend
    

    username=YOURNUMBER
    

(YOURNUMBER is something like 351305XXXXXX)

• Incoming Settings
  
  • User Context: YOURNUMBER
    
  • User Details:
    

    fromuser= YOURNUMBER
    

    insecure=very
    

    secret= YOURPASSWORD
    

    type=user
    

    username= YOURNUMBER
    

• Registration
  
  • Register String: YOURNUMBER:YOURPASSWORD@sip.netcall.pt

You also need to go to the sip.conf configuration file and change the context from "from-sip-external" to "from-trunk".
