This is the error I’ve been getting whenever a call drops:
[2013-11-07 09:25:08] WARNING[13264] chan_sip.c: Session-Timer expired - 3be8145a3baef8fa7f4891302fa2796e@MY_SERVER:5060
the “Session-Timer expired” in the line is what makes me think there is a timer value that is out of order.
What can I do to gather information on this issue?
