Summary:                    [patch] Support for physical tapping in PRI lines
Description: 
It is possible to tap E1/T1 links physically and receive 2 E1/T1 cables to
receive Tx and Rx media and signaling in another box for the tapped line.
This patch and Asterisk branch allows to handle this tapping lines.
Asterisk (through chan_dahdi.so) will detect a call in any direction (to or
from CPE/NET) and create a new call in the monitoring PBX, of course any
transmission is disabled (therefore dahdi_write drop any frames being
sent). Given that tx and rx are separated in 2 dahdi chans, chan_dahdi
creates internally a dahdi conference that is used to mix the tx and rx
streams into a single stream that dahdi_read will use to return frames to
the core.

Hey Guis,

I tested and i'm using the line tapping resource developed by moy. I
talked many times with Moy, when moy started to develop this i'm starting
to develop to, but Moy is a very fast Guy and know much better the dahdi
structure, well, perfect patch, working very very fine.

Everthing work perfect using any pri isdn variants.

Hey Mr. Tood, that feature is underful thing to put on trunk of asterisk.

If you need something, please tell to me, i can send everthing logs or
reports if you need.

Thanks, thanks moy.
