Abstract
A telecommunication network establishes a telephone call from a first location that generates compressed voice packets to a second location. The telecommunication network includes a plurality of switches, a first interworking function ("IWF") coupled to the first location and coupled to a first switch of the plurality of switches, a second IWF coupled to the second location and coupled to a second switch of the plurality of switches, and a network database coupled to said first switch. When a telephone call is initiated from the first location, the first switch receives signaling information from the first location. The first switch then queries the network database based on the signaling information and determines whether the second location uses compressed voice packets based on the query. Finally, the first switch establishes a connection between the first IWF and the second IWF if it is determined that the second location uses compressed voice packets. The connection bypasses the plurality of switches, and therefore reduces tandeming in the network.
