Changing Outgoing Number

I know this question has been asked a but of different ways but there always seems to be a slight different from what I need.

I have 2 Security System devices that run into some ATAs. The ATA are registered to my CUCM 9. Heres what I want.

I have a main line number of 945XXXX that all phones are seen as externally. I want to change that for these ATAs. Instead of being seen as the main line I want to see them at 955XXXX.

I have the Route List Use Calling Partys External Phone Number Mask to On. I then set the External Phone Number Mask on the DN on the ATA to 955XXXX. In the Calling Party Transform Mask ffield under the Route List I have my main line of 945XXXX.

However, the ATA is still seen as the main number when dialing out 945XXXX.

What am I missing?

Thank you

Jason

You could do a DNA and see where its been overwritten. Also, does the route pattern have Use Calling Partys External phone number mask to On?

Ill do the analysis and see what I find.

The route pattern does not have it on. I was under the impression the route list would take precedence though I could be very mistaken.

You're correct that downstream options do override it. For reference, here are the places it could be influenced:

  1. Route Pattern
  2. Route Group Appearance
  3. Gateway/Trunk Transformation Patterns
  4. IOS voice translation-profile
  5. Provider ignoring what you set and forcing the ANI

Re: Changing Outgoing Number

Im tempted to think its something at the provider based on this fact:

When I removed the 945XXXX number from the Calling Party Trasnform Mask Field, its turned into a number that we arent currently using.

Thoughts on that?

Changing Outgoing Number

This could potentially be provider overriding. if you have a PRI and a Cisco Gateway, you could do a debug isdn q931, test the call and see what you are sending and if its different from what you receive, it will be provider based. If its a sip trunk and Cisco gateway, debug ccsip messages should help you.

Re: Changing Outgoing Number

It is a PRI and Cisco Gateway. Ill see what I can dig up on that end.

It might be in Group Appearance on the CUCM. I dont think the Gateway would be the issue but I posted the relavant Gateway (2951) config here just to see if maybe I missed something.
