Good day! I have the foolowing issue with Cisco Phone 8941. When I make an external call(to PSTN), I have a problem with conversation (delay, choopy speech, dropping some RTP packets). I don't have any problem when I make local calls. I tried to set the command "bearer-cap speech" (according to https://supportforums.cisco.com/discussion/11485236/8941-external-call-issue), but it didn't fix my issue. I think 8941 try to sent video with audio. How can I force 8941 not to sent video for external call? How can I force 8941 to use a codec 711u instead of 722?
