T.38 and H323 Configuration

[Kevin Martin]

We are in the process of testing XMedius Fax solution with our production CUCM 7.1 systems.  I have a SIP Trunk established between CUCM and the XMedius server and it is working fine.  I also have a gateway setup pointing to CUCM via h323.  The communication passes through to the XMedius Server but when XMedius requests T.38 instead of G711ulaw, I get "488 Not Acceptable Media" when looking at the call flow.  Any Ideas?

Thanks,

Michael.

Make sure that the matched dial-peer has T.38 configured on it.  You can configure it globally under 'voice service voip' and it will take effect on all dial-peers.

If you still have issues, get 'debug voip ccapi inout' and h225 asn1 and h245 asn1 during a switchover, and post the relevant config.

Michael,

I am wondering if you found a solution to this one? 

Steven, if the offer still stands, I am posting the debug and relevant config here:
