  • H.323 to SIP interworking for call forward/redirection
    Patent number: 8351355
    Abstract: In a particular embodiment, interworking between an H.323 protocol and SIP protocol for a call forward/redirection is provided. A first user may call a second user. The second user may have set preferences that cause a call redirection/forward to another end device. The end device may be associated with the second user or another user. Different preferences for the call forward/redirection may be provided. For example, a call may be forwarded all the time, when the second end device is busy, when there is no answer, etc. The redirection may then be performed using a gateway. When end devices communicate using SIP and H.323, the gateway provides interworking to provide the call forward/redirection. For example, the gateway maps a 3xx message in SIP to an H.450.3 message in the H.323 protocol, and vice versa, to provide the call forward/redirection.
