I'm using 3CX and SPA3102. I'd like to bounce an incoming caller who has withheld his Caller ID to a Digital Receptionist where I can tell him to dial again with the enable CID prefix. The Caller ID field will appear as WITHHELD, and shows as such in the SPA3102 log. However, I'm not sure that 3CX picks this up, as the server log just shows line 10000 ringing. (Caller ID does work as normal when it's not WITHHELD). Is there anything I can do to get this functionality?
