Speech coding selection based on call related information

A variable voice compression ratio device comprising:

• a memory adapted and arranged by a user to contain a plurality of voice compression ratio values each associated with respective call related information;
• a call related information receiver to receive call related information provided by a central office of a telephone company with respect to an incoming call;
• and
• a processor to compare said received call related information with said respective call related information contained in said memory to identify one of said plurality of voice compression ratio values.

A method of setting an effective data rate for storage of a voice message for an incoming call, said method comprising:

• detecting and receiving call related information provided by a central office of a telephone company relating to said incoming call;
• comparing said detected and received call related information with a memory containing call related information pre-set by a user associated with respective ones of a plurality of effective data rates;
• and
• setting said effective data rate for storage of said voice message of said incoming call based on said comparison.

A variable voice compression ratio device comprising:

• a processor;
• call related information detector/receiver means for detecting and receiving call related information provided by a central office of a telephone company about an incoming call;
• and
• call related information memory means for associating call related information pre-set by a user with a corresponding one of a plurality of voice compression ratios;
• said processor being operable for an incoming call to compare call related information for said incoming call to said pre-set call related information in said call related information memory means, and to determine a voice compression ratio for storage of a voice message corresponding to said incoming call based on said comparison.
