Abstract
A variable voice compression device and method in a voice messaging system is provided. The device includes a call related information/coding table or database which contains associations between call related information regarding desired calling parties, and selected coding techniques and effective data rates resulting in varying voice compression ratios. Upon receipt of an incoming call, call related information sent from the central office is compared to entries in the call related information/coding table or database. If a match is found, the subsequent voice message is encoded with a coding technique and effective data rate determined from the matching entry in the call related information/coding table or database. Otherwise, the voice message is encoded with a default coding technique and effective data rate.
