Problem:
New Sip trunk setup for Tierzero provider using Broadsoft Sipserver.
callflow: ITSP - CUBE - CUCM - Phone
Sip trunk is registered and indbound calls working. Outbound calls are working, but only if I replace the ANI with the Pilotnumber.
If I don't replace the ANI with the pilot, I just get a Forbidden.
The provider can only provide a generic guide for UC500 and I cannot see how they sort the ANI issue.
Any suggestions on how to have both ANI and Pilotnumber in the INVITE ?
