Abstract
The present invention provides a sagacious routing engine for use with a session initiation protocol (SIP) call. In one embodiment, the sagacious routing engine includes a request manager configured to receive a routing request for an integrated routing target set for the SIP call within a network. Additionally, the sagacious routing engine also includes a route manager, coupled to the request manager, configured to employ a dynamic routing table for the routing request to provide the integrated routing target set to the request manager for routing the SIP call within the network.
Claims20
A sagacious routing engine for use with a session initiation protocol (SIP) call, comprising:
- a request manager configured to receive a routing request for an integrated routing target set for said SIP call within a network;
- and
- a route manager, coupled to said request manager, configured to employ a dynamic routing table for said routing request and to provide said integrated routing target set to said request manager for routing said SIP call within said network.
A method of routing a session initiation protocol (SIP) call, comprising:
- receiving a routing request for an integrated routing target set for said SIP call within a network;
- and
- employing a dynamic routing table for said routing request to provide said integrated routing target set for routing said SIP call within said network.
A communications network, comprising:
- an Internet protocol (IP) domain;
- a public switched telephone network (PSTN) domain;
- a sagacious routing engine, coupled to said IP domain and said PSTN domain, for use with a session initiation protocol (SIP) call, including:
- a request manager that receives a routing request for an integrated routing target set for said SIP call;
- and
- a route manager, coupled to said request manager, that employs a dynamic routing table for said routing request to provide said integrated routing target set to said request manager for routing said SIP call;
- and
- a media gateway, coupled to said IP domain and said PSTN domain, that constitutes at least a portion of said integrated routing target set for routing said SIP call.
