We are trying to set up a SIP trunk between our CallManager and the S8700 at HQ. We've followed everything in the Avaya document title "Configure Avaya Communications Manager and Avaya SIP Enablement Services for SIP Trunks with Cisco Unified CallManager" to the letter however SES refuses the calls from the CallManager with Forbidden- invalid domain in header.

Does anyone have experience with this configuration or know of a way to make SES accept SIP from another domain? I'll be posting this in the Cisco forum as well.

Thanks!
