The topology is there are two Gateways for this site and each has a SIP Trunk to CUCM. IP's ending in .220 for one and .221 for the second gateway.
Inbound calls come in a PRI on the .221 Note: each router has a PRI, one gets local, the other gets LD and INTL, dial-peers are sip -h323.
It appears to me that the two SIP Trunks are causing an issue with this one fax machine, it appears the internal server error is due to calls getting routed based on both the .20 and the .221 which is causing a routing issue, it seems,, which is odd as other faxes on other Vg 224's at same site seem to be working fine. There at least two faxes on this same VG having this issue. Short debug follows:

what they mean. This document attempts to br...
