push to talk over cellular (PoC)

A service that provides direct one-to-one and one-to-many voice communication in the cellular network. Calls can be started both to individuals and to talk groups with just the push of a key. Call connection is almost instantaneous and the receiver does not have to answer the call. A specifically PoC-enabled terminal is needed for the service.
