Caller ID is the caller ID, i.e. the calling line identification, CLI, is the number that is displayed when a call comes in.
Freezvon transmits your virtual numbers as Caller ID. In the transmission of Caller ID in calls that are made using virtual telephony, both the originating party and the receiving party of the call are involved. The Caller ID may be changed at any of the nodes of the call route before it enters our network or after it is sent from our network.

Please note that we do not guarantee Caller ID for outgoing calls, especially for outgoing calls from local numbers within the Eurozone, China, Turkey, UAE, Saudi Arabia, Belarus, Russia and Ukraine (this type of virtual telephony traffic is or may be blocked under the laws of the country, or the actions of local providers).
