Multiple-termination routing in a wireless network environment with an internet protocol core

A switching center, comprising:

• one or more processors;
• and
• one or more memory mediums coupled to the one or more processors, wherein the one or more memory mediums store program instructions that are executable by the one or more processors to:
• receive a call delivery request, wherein the call delivery request includes a called number;
• determine call features associated with the called number;
• determine whether the call features include multiple-termination routing information to a plurality of potential terminating devices;
• when the call features include multiple-termination routing information including
• at least one termination to be routed utilizing Session Initiation Protocol (“SIP”), initiate a call setup to each of the plurality of potential terminating devices;
• and
• when the potential terminating device is a public switched telephone network (“PSTN”)-protocol based device, sustain signaling communication with a media gateway for enabling the PSTN-protocol based device to interwork with an Internet Protocol (“IP”) core while initiating the call setup to each of the plurality of potential terminating devices.

A non-transitory, computer accessible memory medium storing program instructions for multiple-termination routing in an wireless network, wherein the program instructions are executable by a processor to:

• receive a call delivery request, wherein the call delivery request includes a called number;
• determine call features associated with the called number;
• determine whether the call features include multiple-termination routing information to a plurality of potential terminating devices;
• when the call features include multiple-termination routing information including at least one termination to be routed utilizing Session Initiation Protocol (“SIP”), initiate a call setup to each of the plurality of potential terminating devices;
• and
• when the potential terminating device is a public switched telephone network (“PSTN”)-protocol based device, sustain signaling communication with a media gateway for enabling the PSTN-protocol based device to interwork with an Internet Protocol (“IP”) core while initiating the call setup to each of the plurality of potential terminating devices.
