Phonzo SIP trunk settings

Asterisk/FreePBX/AsteriskNOW settings for working SIP-trunking both inbound and outbound with Phonzo in Norway..

Phonzo will not allow outbound calls from Asterisk. To get outbound calls over Phonzo working, you will have to convince Phonzo that your Asterisk is something else. I will not tell you how here, but I may provide you the information if you send me an email ;)

Replace 87654321 with your Phonzo account number/phone number, and passW0rd with the associated password as given by Phonzo.

Outbound Caller ID: 87654321

Register String:
87654321:passW0rd:4787654321@sip.phonzo.com/87654321
  • Note the use of fromuser, username and authuser, as well as the user:pass:authuser@siphost/DID format of the register-string
  • fromdomain is required to make asterisk send data that Phonzo undestands on outgoing calls
  • canreinvite=no is essential for outbound audio on outbound calls
  • Adding the DID on the register string is essential to have inbound DID work in your dial-plans

The DID, Direct Inward Dialing Number, is required if you plan to have more than one trunk, and/or more than one inbound route.
