extension B finishes the call, IP PBX will ring extension B within a minute. When extension B is picked
up, IP PBX will ring extension A to connect the call. Extension A call also press * to cancel, and will
connect to voice mail.

extension A calls to extension, and extension B is in use, the second line of extension B’s IP
Phone will ring.
