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.
