Abstract
A method is provided for forming a multi-media communication path between at least first, second and third communication devices coupled to a multi-media provider system during post answer call redirecting and/or teleconferencing. The method includes receiving and processing a first call request at a circuit-based portion of the multi-media provider system for forming a first communication link between the first and second communication devices. Thereafter, predetermined attributes of the first communication link may be sent to an IP-based portion of the multi-media provider system for configuring the IP-based portion of the multi-media provider system to process a subsequent request to execute post answer call redirecting and/or teleconferencing. Upon detecting the request to execute the post answer call redirecting and/or teleconferencing in the first communication link, the IP-based portion of the multi-media provider systems responds by forming the multi-media communication path between at least first, second and third communication devices.
