I'm using Freeswitch as a PBX for OpenBTS, to route calls from mobile phones to VoIP providers.
When bridging a call from a cellular handset to a mod_skypopen interface, I get the following error as soon as the Skype call is answered. The handset then hangs up. It appears the problem lies in the 'audio codec compare' phase.

Any advice on forcing a transcode or otherwise having the Audio Codec Compare result in a successful bridge is appreciated.
