Change Caller ID for Individual Skype for Business/Lync 2013 Users on Sonus 1k/2k SBC

I've had multiple clients approach me with the same scenario in Skype for Business/Lync 2013: <NAME> in <DEPARTMENT> wants to change the caller id for their individual DID or extension to a different number.  For clients that have a Sonus 1k/2k SBC, this is very easy to do.

Transformation rules on the Sonus 1k/2k SBC allow for manipulating the 'Calling Party Address/Number' field. The 'Calling Party' is who initiates the call. If we change the calling party from the users number to the number they want, that addresses their issue.

First, we create a transformation rule. Below are examples for both an e164 number and an extension:

Extenstion Example

E164 Example

Lastly, we'll also need to include a 'catch all' rule. The 'catch all' rule catches any other number and passes it through without manipulation. Below is an example:

Catch All Example

After our rules are created, we'll need to make sure they are ordered correctly. Transformation rules are evaluated from top to bottom. If our 'catch all' rule was ordered above our e164 rule, for example, then our e164 rule would never be evaluated. Clicking the pencil icon at the top of the page will allow us to use arrows to move our rules up and down the list of tranformation rules. Use the arrows to move any rules you created above the 'catch all' rule and then click save.
