Hi Folks,
I meet a problem, for outgoing calls, does Cisco ISR support to choose PRI line based on calling number if customer has over 2 PRIs?
dial-peer voice 911 pots
translation-profile outgoing callingnumber1
destination-pattern 911
no digit-strip
port 0/0/0:23
DID 1
Translation-profile callingnumber1 means If assigned extensions dial 911, their calling number will translate to DID 1, and these extension will take the first PRI dedicatedly.
dial-peer voice 911 pots
translation-profile outgoing callingnumber2
destination-pattern 911
no digit-strip
port 0/0/1:23
Translation-profile callingnumber2 means If other assigned extensions dial 911, their calling number will translate to DID 2-5, and these extension will take the second PRI dedicatedly.
Does it works?
Thanks.

Hi
Not with the config you have proposed...
Essentially what you need to do is control the routing in/out with prefixes. Configure your phone system to send the called number with a prefix that matches a dial-peer that is linked to a specific PRI.
E.g User A dials 91234, CUCM sends 11191234. Gateway routes 11191234 to ISDN-1, stripping the leading digits
User B dials 91234, CUCM sends 222912345. Gateway routes 22291234 to ISDN-2, stripping the leading digits.

Hi
It's the same idea - you can use the same RL/RGs if need be. it's just careful dial plan design...
You need a CSS for each user group.
Each CSS has unique route patterns that match normal-dialled numbers, and insert a prefix.
When that prefix is received on the gateway, the gateway will route differently based on the prefix, and strip the prefix appropriately for the PSTN.

Hi Aaron,
How to associate the assigned user and the route pattern on CUCM?
Thanks a lot.

Hi
You would assign a different CSS to each group. That CSS would allow the user to dial normally (e.g. 9 for outside) but each CSS would have unique Route Patterns that insert the prefix.

Thannks Aaron,
The customer has a h.323 gateway. There is only one route group on CUCM, How to choose the assigned PRI based on the configuration of route list?

You are awesome.
About incoming calls, Telco will route the calls to assigned PRI based on destination number. Do i need to configure dial-peer based on answer address?
Thanks.

guys, why you do not simply configure dial-peers with answer-address?

Hello Aaron,
I am having the similar requirement - along with that. Customer also wanted PRI Redundancy.
Means - if one of the PRI goes down - the call has to be routed through other PRI.
Any ideas to achieve this request.

Hello,
Yes it;s possible, using (answer-address) to match calls based on originating calling number instead of (destination-pattern).
