Summary: [patch] mISDN rejects incoming calls (reopened)
Description:
have a trixbox installation with a b800p with 6 ISDN lines configured in
PTP mode. The asterisk version is 1.4.25.1 and misdn 1.1.7
The system works well but I Sometimes, usually twice a week the system
gives me a dial out failure. That happens usually when pbx is under heavy
load
In this circumsance I can receive calls as before but I cannot perform
outbound calls.
The only solution is to reach the ssh console in the system and give an
"mISDN restart", after that the system returns to normal operation and i
can perform outbound calls again.
The misdn log file reports a problem related to issue

I also checked the .c file to see if the patch reported in 13488 is
included.
As expected I found the code regarding the patch.

Occasionally losing use of B channels in chan_misdn.
I have not been able to reproduce the problem of losing channels.
However, I have seen in the code a reentrancy problem that might give
these symptoms.
The reentrancy patch does several things:
1) Guards B channel and B channel structure allocation.
2) Makes the B channel structure find routines more precise in locating
records.
3) Never leave a B channel allocated if we received cause 44.
The last item may cause temporary outgoing call problems, but they should
clear when the line becomes idle.
