I'm deploying a UC520 using Broadvox SIP trunk service and DID's
One main number is used for registering the trunk.
All invites of incoming calls use the main number in the URI. The DID's use the FROM field as the DID differentiator. The problem is that the UC520 is routing all calls based on the number in the invite and not the DID in the FROM field.
Is there any way to make the UC520 look at the FROM field instead?
