Hello all,

I need your help please.

I have a cucm 12.5 integrated with cisco gateway ISR on H.323 , in this gateway i have one card E1 .

My cstomer want to implement this scenario with one E1 , unscrewed in channels

1 -Channel 1 to 8 with a number (05XXXXXXXX)

2 - Channel 9 to 10 with a another number (05XXXXXXXX)

3- Channel 11 to 12 with a another number (05XXXXXXXX)

4- Channel 13 to 14 with a another number (05XXXXXXXX)

For a user want to use number on channel 1 to 8 for outgoing call , he must to take tha call by clicking before on the 6

exemple : 605XXXXXXXX

For a another user want to use number on channel 9 to 10 for outgoing call , he must to take tha call by clicking before on the 7

exemple : 705XXXXXXXX

For a another user want to use number on channel 11 to 12 for outgoing call , he must to take tha call by clicking before on the 8

exemple : 805XXXXXXXX

For a another user want to use number on channel 13 to 14 for outgoing call , he must to take tha call by clicking before on the 9

exemple : 905XXXXXXXX

Could you confirm to me is that possible ?

I just thought of another detail as it pertains to tying certain users to certain channels. That will only have an impact on outbound calls. The PSTN provider makes the decision on channel selection for inbound calls. That could leave a user group with those channels in use by somebody else on an inbound call, so they would not be able to place outbound calls. The admission control method works in both directions.

If the customer is trying to control how many PSTN talk paths are used, I think a better way to do that might be by using admission control. Put the gateway in one location, and each group of phones in a separate location. Assuming G711(u or a), configure a link between the phone location and gateway location of of 64K per call you want to allow. Trying to restrict channels in the PRI seems an overly complicated way of handling that.
