CCM traces would confirm the codec negotiation, or a debug h245 asn1 on the gateway. CCM traces with 245 enabled will be easier to follow IMO.

<div>If you are set for g.711 everywhere then the first thing I'd check is if you have "optimize for low bw" enabled in CIPC preferences. This forces it to g.729 which CUCM and IP phones would have no problem with but if your gateway is configured for only
711 your call will fail media negotation.</div>

Using the Cisco Communicator client I can dial phones inside my org just fine. However when I attempt to dial out to the PSTN I get a busy signal. If I try to hairpin through the PRI (dial full 10 digit to a DID already on my PRI) I see the call go out of
the PRI and a call come in to the dialed number but then it disconnects and I get a busy signal. I’m guessing it’s a codec issue, the signaling works, but once it tries to shift codecs for the RTP it can’t negotiate correctly with the H.323 gateway and the
call fails.<o:p></o:p></div>

Does this sound legit, or is there another potential issue I’m missing?<o:p></o:p></div>

How would I confirm codec negotiation in a 2821 and Cisco Communicator scenario?<o:p></o:p></div>
