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!).

titogarrido: It does seem like you might have a noisy line.

In my case the telco is running unbalanced E1 over coax from their digital
switch to the closest CO to our building; into a balun to convert it into
balanced twisted pair; into an SHDSL modem; over SHDSL and back to balanced
E1 at our site; over a few metres of UTP into our Digium card. It's an
unusual setup and it took a few tries to find a reliable balun. Until then
we saw dozens of sync losses/recoveries per second during the day, and at
night the lines would block and unblock themselves continually (noise on
the CAS bits?). Maybe some of this applies to you.
