Restrict CID for one DID on trunk

[Integra]

Hello,

Is it possible to set up a CID rule to restrict only certain numbers from dialing a certain DID on a trunk with multiple DIDs? We would like to be able to whitelist only certain numbers from reaching DID "X" without inpacting DID "Y" that is also on the same SIP trunk.

I'm not certain about a whitelist, as such. You should be able to route certain caller IDs to one destination (an extension), while all others will go to the "default", whatever that may be.
