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

I don't know if you have answered this one already on your own, but I wanted to ask a few questions on some ideas that I had on this. One, have you made sure that all devices are reachable? I was thinking that maybe IP Routing was not enabled. I know that I have a lot of customers that forget this one and think to far ahead...hahaha maybe me also.
Also, Allowed ip addresses in your SIP configuration? The fact that they ring shows that signalling is working but maybe RTP can't reach all devices.
Just some thoughts,
Good luck,
Keith
You might try this:
voice service voip
no ip address trusted authenticate
Hi jfaranda,
I could be wrong here but i cant see your voice vrf XXXXXX command on your second router.
Thanks
