it came from »linphonec -d1« log. > I would be suprised it is in linphone logs: received= is set by servers > (or the UAS part of the client, but not for registers since linphone > does accept incoming registers). At the moment I have no access to the tersting machine, but I'll test again with the registrar running on an different port. I suspect a transparent SIP proxy from the ISP in between, who changes the addresses silently. I'll have a look with the kamailio running on a different port an report again. > If it is in the server logs: it might be the server that adds it > automatically to recall where to send the register's response back. > If it is captured with wireshark running on the server's machine, then > that would mean that there is some kind of poorly intelligent NAT > between linphone and kamailio that is trying to make some SIP > proxying.... > It arrives sometimes. sips (encrypted sip) would help in getting rid of > these stupid nats, but it's not yet supported in linphone. Is this on the todo list for the near future? BTW what about encrypted RTP?
