Summary:                    [patch] MFC/R2 support for chan_zap
Description: 
Here we go. This is my first try to give R2 support to chan_zap. I'm sure I
am missing locks and/or features here and there but I have tested it
internally with success with a considerable amount of concurrent channels
(64). That's the best I can do with the hardware I currently have (more
coming!).

Hy Moy,

How are you? I hope you are fine.

One more problem for us, i think this is more complex.

I was using Core2Duo for tests with One TE4xxp ( 4 E1 ports ), Port 1:
ISDN Ctbc Telecom, Port 2: R2 Embratel and this OK, in this night we
changed this Quad-Span by 2 Te110P, now i have one big problem....

In Rando times but with interval < 10 minutes i have this error in all R2
ports:

Alter 2~5 seconds I receive in all ports:
