Abstract

A wireless communication device without IP capability nonetheless communicates with an infrastructure that uses IP. To effect call set-up, an over-the-air (OTA) origination message from the wireless communication device is received by an infrastructure component, which in turn generates IP-based messages having headers that are extended to include information related to the OTA protocol. The IP-based messages with extended headers are then used internally to the infrastructure to effect call set-up.

at least one second telephony infrastructure component operable to receive the SIP message for use thereof in establishing communication with the wireless communication device,

wherein the OTA protocol message is a code division multiple access (CDMA) initiation request message, the information represents CDMA call set-up parameters-that are related to the OTA protocol and are not related to voice over Internet Protocol (VOIP) communication within the infrastructure, and the information represents MOB_TERM status of the wireless communication device.

4. A system, comprising:

at least one Session Initiation Protocol (SIP) header generated by a virtual Internet Protocol (IP) endpoint component for a SIP message, the header including information derived at least in part from an over-the-air (OTA) protocol message from a wireless communication device; and

at least one telephony infrastructure component operable to receive the SIP message for use thereof in establishing communication with the wireless communication device,
