Hello, I participate in developing a TTS/ASR (text-to-speech / automatic-speech-recognition) application and we need to support SIP in the application, so we decided to use PJSIP library. It is very simple to use the library (pjsua-lib layer) and it provides sufficient functionality. But there is one thing I miss in pjsua-lib: data loss detection, which can be very important especially for ASR part. The only way to do this I found, was to parse string returned by pjsua_call_dump() and get lost packet count number. Is there a smarter way to get the information without modifying library source code? No matter if it is lost packets count or lost frames count, but information that this frame does not contain real data would be very valuable. Thanks. Vali
