hi, there is a longstanding issue with CSipSimple not ending a call: http://code.google.com/p/csipsimple/issues/detail?id=386 as far as i understand it, when i press "end call", it sends this to the server, and does not get a reply, or not the appropriate reply. CSipSimple then just stays open and lets the user feel the whole timeout period. Given that sip over mobile internet is such an unreliable connection, a voip server has to deal with "dying" clients without saying "bye" all the time, and i am pretty sure this is properly implemented. so i was wondering why CSipSimple canont take a more aggressive approach and just ending the connection if the user desires to. the issue mentions that pjsip/pjsua should be responsible for this. i tried to find if there is already an issue, and found: http://trac.pjsip.org/repos/ticket/1049 does this match the CsipSimple issue? i am pretty sure there must have been some discussion about this in the past so bear if i did not find the correct one now ... rupert.
