We have been using fax over SIP trunks through SIP converter boxes (Cisco ATA-122) without using t.38. DID numbers point to internal extensions assigned to the SIP boxes. Completion rates are OK, not great. We have t.38 licenses, so I thought I'd try it out. I followed the instructions in the on-line help (see attached file for these instructions), but I'm getting the following error in the log:
Port:11930f90 Failed to Apply Policies.Most likely T38 is not allowed in the zoning plan. (substate 7)
The error only shows up when I enable t.38 in the SIP boxes. Has anyone seen anything similar?
