Cannot place calls, get 'could not determine call peer state' error


For work I’m trying out different clients to get SIP working in the office. I can connect to the server, but it seems I can’t place calls. Right after the sad/error notification sound from Jitsi, I copied the log files. There, on the last line I see the following:

2019-11-18 17:18:21.109 SEVERE: [232] impl.protocol.sip.CallPeerSipImpl.hangup().1057 Could not determine call peer state!

Unfortunately I cannot attache the whole log as ‘new users aren’t allowed’ :confused:

Does this indicate anything to the developers? Anything (else) I should provide to debug this issue?
