Troubleshooting proxy phone ASA output

[mmedwid]

I am trying to troubleshoot a one way audio problem with my proxy phones.  The

61.47.124.59 address is the outside/inside media address and 10.10.10.70 is a

SIP voice gateway.  Would appreciate is someone could tell me what the error

messages relative to SRTP are saying. Thanks.

The ASA Phone Proxy is complaining about RTCP packets there (odd number port numbers), to keep this from happening, you can disable RTCP on the phone configuration page in call manager.

Hmm - I checked the device settings for the proxy phones and I see that RTCP is in fact disabled.  I added some nat and firewall config at the voice gateway.  Perhaps it has something to do with that.
