[cisco-voip] Grouping PRI Channels

[Mark Holloway]

Here is an example of my AS5400 gateway where I receive calls with 4444 as
the prepend.  Depending if the call is Inter or Intra lata, I route the call
to the appropriate pots dial peer (trunk group). I change 4444 to 0071 for
Inter LATA, toll free, and services (411, etc), otherwise strip 4444 and
route out the CAT4 (Inter LATA) trunk group.  Notice I also strip the 1 from
the 10 digit number before sending it to the Nortel DMS.  This is because
the DMS doesn't like an 11 digit telephone number.

Friends,

I am working on voip setup where Ericsson PBXs are connected with cisco 3800
routers. You can see topology below:

Phones-------PBX-A----Router-A-------------------------Router-B------PBX-B--
------Phones 

PBX is connected with router through E1 Pri (qsiq) where as Router are
connected via E1 link.

Issue is: before voip setup PBXs are connected point to point and TDM
engineer divided channels in to two groups. One from channel 1-18 for
subscribers and other from 19-31 for Operators. So when subscriber come on
trunk, it was assigned channel from 1-18 and operators are assigned channel
from its range. Now i put routers between PBXs so when operator of PBX-A try
to dial number, operator is assigned channel from its range on PBX-A and
forward to Router-A. When that call reaches Router-B, it assign first
available channel on pri that is connected with PBX-B. But we want channels
are assigned by Router-B must be same that assigned by PBX-A. 

Hope you will have understand my problem. And please tell me the
solution.......You immediate response will be appreciated.

Best Regards
Rameez
