Hi all, I'm seeing this "Bad RTP pt" error which is mentioned in the FAQ as well. My remote-endpoint is a Softphone called X-Lite 4, which is the latest version I can find. Below are INVITE, 200 OK response, and the error message. Any idea why I keep seeing the error messages, even when I've set the codec priority of PCMU/8000 to the highest? (In fact I don't quite understand why GSM/8000 is being used instead as well) Thank you.
