Sorry if this has been asked somewhere else, but I need to block sending caller ID, on a per call basis. Using a Cisco SPA112.
The VOIP DID was ported from PSTN so I can't disable it in the member facilities, and dialling *67 doesn't work (just gives engaged tone for all subsequent calls and requires config restore to rectify )
Any ideas?
It is not possible to block caller ID per call basis. As per with PSTN service it is applied for all calls (i.e. on or off). If you want to block your caller ID please PM me your service number and I will get it done for you.
