Hi,
I have a scenario where i have a branch site with a 2821 and some faxes connected to a EVM-8FSX/DID card the gateway is controlled by mgcp on a cm 5.1.2 at the headquarters. I have a situation where someone sends a fax from the pstn to one of my fax but the fax is never received. I have made same testes and notice that when the call arrives to the gateway the call answered by the fax but only the isdn bri interfaces changes to t38 the fxs port never changes. If I call from the same pstn number to other fax on the same gateway and the call is answered and both ports (fxs and bri) change to T.38 fax relay.
PORT CODEC VAD VTSP STATE VPM STATE
============== ========= === ==================== ======================
2/0/2 g711ulaw n S_CONNECT FXSLS_CONNECT
2/0/11.1 t38 n S_CONNECT
PORT CODEC VAD VTSP STATE VPM STATE
============== ========= === ==================== ======================
2/0/0 t38 n S_CONNECT FXSLS_CONNECT
2/0/9.1 t38 n S_CONNECT
Does any one have an idea of what could be the problem.
Thanks

Hi
It would have been better if you had attached the configuration from the 2821 on the branch as well as the router that is sending the call out to PSTN (if different).
