<#root> .Jun 4 21:06:43.461: ssaSetupPeer cid(19) peer list: tag(400) called number (5074)

On the termination voice gateway, the first line of the debug voip ccapi inout call trace (as shown here) is a cc_api_call_setup_ind message with a peer_tag option that refers to the inbound VoIP dial peer on the termination gateway. debug voip ccapi inout - Terminating Gateway

Incorrectly configured dial peers on one or both sides After you confirm that the correct dial peer is matched (in this case dial-peer 100 for the origination gateway and dial peer 400 for the termination router), confirm in the configuration that the dial-peer is configured correctly for fax. Some common errors to check for on both sides of the call are these: Fax relay is disabled (that is, the fax rate disable command has been issued on the dial peer) while a low bandwidth codec has been in use. ○ The dial peer on one voice gateway is configured for Cisco fax relay, but the other voice gateway is a Cisco 5350/5400. The Cisco 5350/5400s only support T.38, so the negotiation fails. ○ •
