I recently got a SNOM 300. Works fine, but I notice ongoing messages in the log like this:
Nov 4 10:13:56 DEBUG chan_sip.c: Stopping retransmission on ‘email@example.com’ of Request 102: Match Found
When I tried restarting asterisk (and said ‘gracefully’ instead of ‘now’), my session was dropped, but asterisk kept running - apparently it thought there was a SIP call ongoing. Had to hard-kill the asterisk process. Any idea what is causing these?
