After upgrading to 4.07 I am now getting the message "Incompatible media parameters, can not establish call" on all outbound non-PSTN calls. Inbound calls are fine. I called my VoIP provider and we ran some traces.

Basically it looks like everything is ok until the call is accepted. In the trace the epygi then sends an ack, and then immediately disconnects.

Any ideas?

I'm using Cisco 7960's and the g729a codec.
