So... thank you for the AcceptUnregisteredCalls=1 suggestion. I hesitated using AcceptUnregisteredCalls=1 because of the ominous warning about security in the manual and I didn't know exactly what security risks that would expose me to. Someone else explained that its not really a security risk unless you need to restrict who can call your endpoints. Setting AcceptUnregisteredCalls=1 works... well mostly. It seems that the Sony PCS-1 units have some incompatibility with GnuGK which causes the call to fail even with AcceptUnregisteredCalls=1. Polycom units work just fine. -- Harris L.
