Forwarding OriginatorCallerID with anonymous calls

[AlexACS]

Hi there,

We have a 3CX v15.5 setup with caller ID being presented on diverted calls - inbound caller ID gets presented to the recipient of the diverted call via P-Asserted Identity set to "Originator Caller ID". Works a treat, thanks to our provider allowing this (signed some documents first).
However we have one problem - if the original caller is blocking their CID (3CX receives a call from 'unknown') and this gets diverted to a mobile phone - 3CX doesn't seem to know how to pass on the 'unknown' CID and instead presents the mobile with 3CX's primary SIP peering number, which is causing some confusion.
Does anyone know if it would it be possible to (a) present 'unknown' CID on these diverted calls, or (b) present the outbound CID of the extension who diverted the call?
NB: I assume option (b) is unlikely as this would be an 'all or nothing' setting applied all calls regardless of CID, but worth putting the question out there...

TIA!

Alex

Fixed, or at least worked around.
Created an inbound CID rule that turns "unknown" (without speech marks) into a random number e.g. 0000000
Then and outbound CID rule that turns 0000000 into a generic number of my choice.
Looks like that'll do it for now as opposed to passing through 'unknown' at this stage.

Good deal. Thanks for posting the steps to resolution.
