Select specific number as Caller-ID

Hi there,

I have a CME system with UC540 and a number of SPA509G phones. The reception phone has several extension numbers associated with it and I'd like to select one extension number to appear as Caller-ID.

How to configure one specific extension number as the Caller-ID on Cisco CME?

Regards,

Tuan

Select specific number as Caller-ID

Hello Tuan,

I'm not aware you can set a specific calling number per ephone - but one possibility is to add a translation-rule to your configuration that will translate all numbers of the phone to the one you want as caller-id.

Example - you have 200, 201 and 202 as lines on your ephone but want to use 205 as caller-id: then add a translation-rule that translates 200, 201 & 202 to 205 (or to your PSTN prefix plus 205 if that's what your provider wants to see). It's not an elegant solution, not very scalable but it will do the job for what you are looking for. This is independently of the phone-model that you are using as it's done in IOS.

You can apply that to your outgoing port (in case of ISDN) - so only need to apply it once. Can also apply it on the dialpeer levels.
