Hi, I have compiled and setup pjsua on my debian 5.0.3, and can make outgoing SIP calls successfully with ringing tone (callee). But when I answered the call at the handsets (callee side), the line was just cut with the following log shown. ? pjsua_call.c? Unable to create media session: Invalid media payload type (PJMEDIA_EINVALIDPT) [status=220102] ? If I make calls from handsets to pjsua, debian side can answer the calls without any problem. ? Any hints or advise for my configuration? Where should I re-configure or troubleshoot? ? Many, many thanks in advance!!!!!!
