Internal extension number mask?

I have a customer that has a need to mask their internal extension number when dialing other people in the company. i.e. a support person has his/her extension (1234) but when calls are placed to other IP phones, he/she wants it to show up as "support center x1111", the main support center line.

I'm using cm 3.2(2c) but do not see a way of doing this. Of course, I can do this on external calls, but internal calls have me stummped.

Re: Internal extension number mask?

Copied from email from TAC when I asked the very same question:

********************************************************************************

So, its ip phone to ip phone with no route-pattern involved.

This is doable ..but has a lengthy process to go abt it.

To achieve this we will have to setup a translational table and make

sure that the line which you are trying to hide *always* goes through this

pattern.

Lets say you ahve 2 patterns

phones and xlate

2 CSS'es

phonesCSS and xlateCSS

Then create a translational pattern

the detsination being xxxx (or how many digits you have)

In the calling party transformations , enter the mask.

This translational pattern is in partition xlate and has a CSS of phones i.e

phoneCSS

Now the phone line has a CSS of xlateCSS.

The flow would be,

the call comes into the call manager ..and there is a xlate pattern

associated with it.

It translates accordingly (the calling party number) and then uses its CSS

which is phone CCS

to make the call

Hope it make sense ..

Let me know

Thank you for your reply to this post. I will try this procedure tomorrow (hopefully) and let you know how it turned out.

I tried your approach above to mask a phone number on internal calls and it works great. Thanks for the advice.

Re: Internal extension number mask?

Just a heads up on another solution without having to go through setting up additional partitions and calling search spaces. You can create a translation pattern with an access code like *67.xxxx.

Then just discard the predot and make sure to set your calling transform mask to whatever number you want to show up and now you have psuedo caller-id block with the same access code as most North American phone companies that anyone can access.

Best regards!
