Summary: [patch] mISDN rejects calls - NO FREE CHAN IN STACK
Description:
This issue is similar to 0013488 but somehow different because of the
version used.
I use a Beronet 4 BRI ports card, with only 3 ports configured,
mISDN-1_1_9.1
Randomly, with an average frequence of once every two weeks, but sometimes
two days in a row, mISDN starts to be able to use one port only (2 calls).
The rest of the calls are rejected with :

Other ports are free, but mISDN seems to focus only on port 1...
I usually try to reload mISDN, to restart port 1, port 2, port 3, and
somehow, it works. Today, I restarted ports, but the problem came back very
fast/was not solved... If I restart the server, it's ok, but can't do that
during use...
This is a production server, and it's getting harder to manage...
I'm now trying to change method from round-robin to standard_desc (first
try was standard...)

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.
