[cisco-voip] Grouping PRI Channels

[Justin Steinberg]

Here is one way.

create two ds0 groups on your routers (one for channels 1-18 and the
other for 19-31).  You will need to prefix digits to the incoming call
with a routing code that identifies which ds0 group originated the
call.  Send the call from router A to router B with the routing digits
added to the called party number.  When the call arrives at Router B
you can use destination patterns to match the routing code so you can
send it to the correct channel.  Strip the routing code between router
B and pbx B.
