We've got CallManager lab set up with a SCCP phone registered to a "internal" CM7.1 publisher. The "internal" CM and a 2821 is setup to do MGCP BRI backhauling of one of the VIC2-2BRI-NT-TE interfaces(0/0/0). The 2821 has a BRI cross connect wire between interfaces 0/0/0 and 0/0/1. The 2821 is also configured for H323 and has dial peers associated with BRI interface 0/0/1. Another "pstn" CM7.1 publisher registers with the 2821 via H323. We also have xlite registered as a SIP client to the "pstn" CM.
Whenever the SIP client dials the number of the SCCP phone, the SCCP phone does a short ring and then stops. Can't seem to establish a call at all but some type of alerting is getting to it.. Any ideas?
Use g711 "u" instead of "a" on the Dial Peers. Also configure "Incoming called-number" with a pattern that covers all the sip phones in the VoIP Dial Peers.

Adding the codec preference list to the dial peer got it working. Is there any debug commands I could have run to determine which codec the call was trying to use at the time?
You can issue "show voice call status" which will give you codec being used.
As far as debugging informacion, the following will show codec negotiation:
debug h245 asn1
debug voice ccapi inout
Thanks!
