Abstract
In accordance with a non-limiting example, the system and method places a call from a first call device used by a party A to a second call device such as used by a party B by routing the call from the first call device into a communications server that establishes an internet protocol (IP) call between the communications server and the second call device. A third call device such as used by a party C monitors the second call device. A first SIP invite command is sent from the third call device to the communications server as a pick-up call instruction for the call to the second call device when it has not answered the call from the first call device. A second SIP invite command is sent between the third call device and communications server and the call is transferred from the second call device to the third call device to establish a communications session between first and third call entities.
