Suppress number

[MitelUK2010]

Is there a way to suppress the number between internal extensions?

I.e room to room only displaying name?

COS:

Suppress Delivery of Caller ID Display between Sets
 
Select "Yes" to make the extension number and name private so that neither display on other telephones during call processing. The abbreviation "PRIV" or "PRIVATE" will display instead depending on the set types. This option can be overridden by the Suppress Delivery of Caller ID Display between Sets - Override COS Option.

##Note: Private names and numbers are displayed on Attendant Console.

Is this applicable to SIP?

No idea, don't use SIP devices in general.
