  1. Click on the 'Edit' button on the number you want to forward calls to your SIP Trunk.

  1. Click into the Destination field and type the SIP URI. In this example, we have used the phone number as the 'username' at the IP address of the PBX.
    See more information about SIP URIs here
  1. Click Confirm and the destination should be set. Click Back and the Call Forward section will have updated.

SIP URIs

To configure call forwarding using a TTNC SIP Trunk you'll need to type in a SIP URI. These look a little like email addresses. For example:

These are only examples to demonstrate URI formatting and will not work if set up in myTTNC.

Your SIP provider may not give you your destination in the form of a URI, but you should be able to create one from your SIP credentials;

  • Username – this may be called your account number/name, your 'inbound route' name or simply your phone number.
  • VoipHostDomain – this may be called the 'Domain', 'Host' or could be the inbound IP they provide.
