Incoming SIP to Call Manager 5.0 on H323 GW


Have a 2811 GW registered as a H323 gateway in Call Manager 5.0. Incoming calls from a service provider using SIP not working. When phone answers the call no ok message sent, instead a 503 Service Unavailable message is sent.

Had enabled sip to h323 calls and h323 to sip calls.

Ringin and trying messages are received ok by service provider.

Any clues will be greately appreciated.

Thank you

It may be in your DTMF setup in your dial-peers.

What is the service provider expected to send you?
