Hi all,
I was hoping you could help me troubleshoot a strange voice issue. I have 2 routers running CME 8.6 that are configured in a VRF.

Each phone will ring when dialed, but there is no audio. I ran a few debuggers "debug cch323 rtp" and it appears data is flowing via rtp. When the phoens are dialed and answerd, I ran a "show voip rtp connections" on each router and they both showed active connections.
I tried different codecs under the ephone. Any ideas? Could it be older code, either IOS or phone?
ETA: From the phone I can "??" to get the phone stats. RCVR Pakets : 0
I can ping from phone to phone
