System and method for optimizing telecommunication signal quality
First Claim
1. A method for optimizing telecommunication signal quality for a signal transmitted from a sending station to a receiving station via at least one intermediary station, the method comprising:
- sending a signaling message, distinct from said signal, that interacts with at least one of said stations;
collecting from at least one station that interacts with the signaling message information about at least one capability of at least one station; and
determining a coding scheme dependent on collected information about a capability of a first station and to be used between second and third stations adjacent to each other in the communications pathway wherein the second and third stations are both intermediary stations.

Abstract
An embodiment of the present invention provides a system and method for selecting voice compression and coding based on capabilities of all intermediary networks and links in addition to the capabilities of the end points. The present invention optimizes voice quality by determining a minimum number of new conversions, herein referred to as transcodings, necessary in voice connections, on a system wide basis. According to an embodiment of the present invention, a sender sends a signaling message to a receiver. The signaling message is sent to the receiver prior to sending an actual message. Each entity or device capable of converting voice coding, herein referred to as a “station”, between the sender and the receiver identifies their capabilities to the signaling message. The receiver, which is also a station, also identifies its capabilities to the signaling message. The signaling message may then be sent back to the sender for the sender to determine an optimized series of voice codings to be used for the call. Alternatively, the call receiver, or an intermediate station located along the call route, may determine the optimized series of voice codings to be used for the call and communicate to the caller how the call should be coded.
