Abstract:
A telecommunication network for establishing a telephone call from a first location that generates compressed voice packets to a second location, said telecommunication network comprising:a plurality of network switches;a first interworking function (IWF) coupled to the first location and coupled to a first network switch of said plurality of network switches;a second IWF coupled to the second location and coupled to a second network switch of said plurality of network switches; anda network database coupled to said first network switch;wherein said first network switch is programmed to:receive signaling information from the first location;query said network database based on the signaling information;determine whether the second location uses compressed voice packets based on the query; andestablish a connection between said first IWF and said second IWF if it is determined that the second location uses compressed voice packets, wherein said connection bypasses said plurality of network switches.
