I thought I was the only one affected. SIP was broken for me too somewhere in February, from Wireshark observations what happens is that during the call Ring closes the port 5060 so all packets are discarded, as soon as the call is hung up the application starts to listen at 5060 again. I test it on Debian Sid. To ensure it was not firewall issue I installed Linphone, which worked fine. Best wishes, Bruno
