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...)

Thank you for the update... Do you think it is safe to use this new patch
on a production system ?
