Abstract:
1. A method of setting up a call from a calling device to a called device, via a softswitch comprising a media gateway and a media gateway controller, wherein a calling user operates the calling device, and wherein the called device has an associated Session Initiation Protocol (SIP) client, the method comprising: receiving into the media gateway controller a call origination request carrying digits dialed by the calling user on the calling device, the digits dialed by the calling user including (i) a feature code that designates a predefined packet-data session profile and (ii) a telephone number of the called device; responsive to the call origination request, the media gateway controller consulting a database to determine the predefined packet-data session profile designated by the feature code included in the dialed digits; and the media gateway controller then generating and sending a SIP INVITE message for receipt by the SIP client associated with the called device, including in the SIP INVITE message the determined packet-data session profile, to facilitate setup of the call from the calling device to the called device via a packet-data session extending from the media gateway, wherein the feature code is one selected from a group of feature codes, each corresponding with a respective packet-data session profile, wherein each respective packet-data session profile defines a unique set of packet-based communication session parameters.
