H323 Gateway - forcing outbound calls down a particular E1 Port.

Answered Question
Nov 7th, 2014
User Badges:

Hi,

We have setup a H323 VGW with 2 E1 circuits attached.

Each circuit has it's own DDI Range applied to it.

The problem we face is that when calling out from the phones with the DDI Range

on circuit 2 it is routing out of circuit 1 and showing an incorrect CLI.

 

Is there a way to forces calls from DDI Range 1 to route out via 0/0/0

and DDI Range 2 to route out via 0/0/1

 

Regards

 

Dominic

Sure,

dial -peer one points to one trunk group, dial-peer 2 points to another with extra off-net digit:

dial-peer voice 1 pots
 trunkgroup Local-PRI
 description Local Trunks, Local calls
 destination-pattern 81[2-9]..[2-9]......
 progress_ind setup enable 3
 progress_ind progress enable 8
 forward-digits 11

 

dial-peer voice 2 pots
 trunkgroup LD-PRI
 description LD Trunks LD calls
 destination-pattern 881[2-9]..[2-9]......
 progress_ind setup enable 3
 progress_ind progress enable 8
 forward-digits 11

If this is CUCM then the easiest way is to use steering codes, build separate CSS/PT/Route patterns/Route List/etc for the second group of phones and prefix a digit string at the Route group or route list level, then have different set up dial-peers matching based on those digits that point to the desired PRI.

Thanks Chris for your help - you wouldn't have an example dial-peer/config I could take a look at by any chance?

Hello Dominice,

 

Could you share your gateway config detail as I'm also implementing the same setup.

Regards,

Raaj.
