An update: the problem seems to be more serious than I had previously realised. I had arranged for a bank to call me back while using linphone to talk to them. When the call had finished, I was watching linphone awaiting the incoming call. Nothing. Linphone was displaying the sipgate presence throughout. When the bank contacted me on my mobile , they said that thay had tried the linphone number 5 times, and in all cases the call switched to voicemail. So it would seem that sipgate was flagging that I was not connected/present/online. There was a time when I knew a fair amount about the SIP protocol, but I have forgotten most of it. But there is a time-out for registration and and an (optional) repeated handshake to maintain the presence IIRC. It would seem that somehow linphone is failing to maintain that presence/registration. I don't have any logs to share. If I had expected the problem, I might have enabled logging, but, of course, I was did not expect it. I have been using sipgate without out problems for many years with a variety of hard & soft 'phones. This is under debian testing. I have not logged a debian bug since the maintainer is following this thread. ael _______________________________________________ Linphone-users mailing list Linphone-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/linphone-users
