SIP channel hang ups are progressively getting worse and I'm really
grasping at straws here trying to find out what the cause is. The
problem start, once a week or so the SIP phones couldn't
communicate with the server, though there was no error message on
the server and everything appeared fine on the server. It's now
doing it multiple times a day and I fear having to go back to our
old phone system if I can't find a fix in the near future. When
the SIP channel locks up the only fix is to restart Asterisk. SIP
RELOAD & RELOAD CHAN_SIP do no good.
Here's a few things I've noticed and changes I've made in hopes of
making it better. First, I've currently got 71 active SIP channels
when only 2 people are on the phone. This doesn't happen every
time, but could be part of the cause. The 'ghost' channels are all
INVITES, how do I clear these without rebooting the system?

There is an open bug report on this in the bug tracker already.
I need your help to find what's causing this issue and provided I can
get proper information from you,
will spend time locating the bug.
First, enable SIP history and catch history for these calls that hang
with "sip show history"
Secondly, check the dialplan and tell me more. Where are you calling,
why doesn't the other end respond?
It's usually calls where we retransmit a number of times and then
forget to destroy the calls.
If I can get a better description so I can repeat this, I'm sure the
bug can be killed.
In the bug tracker, there's a patch that will help you. However,
until I find more exact information
about the nature of these calls, I'm unwilling to commit it. To
commit a fix to a poorly defined issue
is usually causing more issues, something I can do in trunk but don't
want to do in release code.
Please send the required information directly to my e-mail address
and I'll take a look.
Thank you for your assistance with this bug.
