DID Extensions

rcarstens991 · ‎05-12-2011

I recently aquried a client with an old call manager system. The call manager is version 4.1. They have a PRI coming into a 2801 router. Some people have extensions that be called directly from the outside. For example, from outside 111-1350, rings extension 350 and so on. The problem I have is that I need to change one of these extensions and cannot find where to. I need to change what inside extension rings when the outside number is dialed. It appears this translation is all done in the router and not call manager, is this the case?

Thank You for your help.

Would be best if you can post your configuration, (remove security related info). We can help you determine how the translations are setup.

Don't you have a voice translation-rule configured?? If that it, please paste that configuration.

There still missing information to understand your configuration, don't you have configured this line: "translation-profile incoming 1", also paste it please.

No, that is all I have.

I am pretty sure that below is the dial peer I need to be working with. The destination-pattern mathes the outside number I want. How do I just change what inside extension this peer goes to? Is this done in call manager?

It looks like CM is doing to the work. Go to Route Plan ---> Translation Pattern on the CM Administration page.

Ya that's what I thought, but I only have one pattern in there and it doesn't match anything we have. The name is 5XX, its on the internal partition, and the transform mask is *XXX.

rcarstens991 · ‎05-12-2011

When someone calls the outside line, the Cisco phone it rings, says call from 91

Can we just forward 91 to the new extension?

Juan Carlos Arias Perez · ‎05-12-2011

Soorry, must be something like this #translation-profile incoming add91

Gateway Translations Rules -

This is the simple analysis: For the DID that end with 3xx they will translate to 913xx. For the DIDthat end in 1xx they will not translate.

Technically there can be longer matches on the DID because there is not 3..$ to terminate the match. But it common to see the this type of patterns match a (dot) per digit as the regex specifies.

Gateway Num-exp

There are 2, not a good practice. These take precedence over the translation.

num-exp 228 325 --> 228 explicitly changes to 325

num-exp 900 199 --> 900 explicitly changes to 199

So thats what going on in the gateway.

The next step is to look at the callmanger for the inbound dial-plan of gateway.

3 ways to this

Run Dialed number analyzer if installed and running
Run route plan report based pattern you want to change, the translations from the gateway and the DID you want to translate
Manually analysis the dial-plan

Manual way summary:

1) identify CSS

2) identify partition in CSS

3) identify Patterns (Translations, DNs, Route patterns) that match the translated DID in the partitions of the CSS for further digit manipulation

Thank you for the detailed response!

The outside number that is being translated does not match those patterns. The outside number is 354-6778. This is a completely different number than all our other numbers.

I don't have a route plan that matches. The DN that it rings, does not have any different settings than any other line. The translation pattern does not match either

rcarstens991 · ‎05-12-2011

I installed dialed number analyser, but what do I use for the calling party and dialed digits. If I use an internal for calling party and the outside as dialed digits or vice versa, nothing happens.
