Channel Allocation E1 PRI

[faizanelahi]

Hello,

We have two PRI's terminating on CISCO 2800 router working as H323 gateway. It is in production and working fine.

Now, I have a requirement of providing 8 dedicated channels to an internal company. Please assist how can i achieve this ?

Regards,

Faizan.

On your CUCM prefix the calls going through the special channels using a
code (e.g. 111). This can be done using TP or called number transformation
pattern.

On h323 gateway configure a voip dialpeer to match incoming calls starting
with 111
On h323 gateway configure a pots dialpeer to match outgoing calls starting
with 111
Assign to the dialpeer a translation-profile to strip 111 and reformat the
number

On H323 gateway configure a trunk group and assign timeslots to it.

controller e1/0
pri-group timeslots 1 - 31
trunkgroup tg-1 1 - 8

Finally on the pots dialpeer assign the trunk group

dial-peer voice 10 pots
trunkgroup tg-1

*** Same can be done using corlists instead of prefixing digits.

Thanks for valuable suggestion.

Is there any changes i need to made to existing dial peers in gateway and route patterns in CUCM ??

Only for new numbers i need to insert a new prefix (111) and add a dial peer for this numbers.

Can we manipulate for incoming calls from PSTN too ??

I will give this a try in couple of days and let you know how it went.

Thanks again !!

Nothing to be done on CUCM since CUCM views this as a single H.323 terminal and does not care what the PSTN termination is.
You cannot control incoming calls. That is done and controlled by your Telco.
