Abstract

Provided is a Dual-Tone Multi-Frequency (DTMF) header construct for all outgoing telephone calls which consists of information about the caller. A template is maintained at participating telephone systems which maps data to DTMF sequences so a sending telephone system can map the data to transmitted DTMF sequences and a receiving system can map the DTMF sequences back to the data.

Method for Communicating Arbitrary Originator Information in Arbitrary
Telephone Network

      Provided is a Dual-Tone Multi-Frequency (DTMF) header construct
for all outgoing telephone calls which consists of information about
the caller.  A template is maintained at participating telephone
systems which maps data to DTMF sequences so a sending telephone
system can map the data to transmitted DTMF sequences and a receiving
system can map the DTMF sequences back to the data.

      There exists prior art for governing telephone call processing
based on originator characteristics and/or destination
characteristics.  The prior art is unable to function in arbitrary
telephone networks because Electronic Mail, Address Book, and
Calendar Systems are not connected to consumer telephones.  A method
is needed for extending caller attribute processing to arbitrary
telephone networks.

      Provided is a DTMF header construct for telephone calls.
Participating telephone systems map known caller attributes to a
series of unique DTMF sequences.  The receiving telephone interprets
these sequences, thereby decoding characteristics about the caller.
In one embodiment, a standard header format exists which
participating telephone systems will emit.  In an alternative
embodiment, a transform table exists which can be shipped to
telephone systems with a phone call.  When downloaded by a phone
call, the telephone system then has the ability to convert caller
characteristics...
