Title : Text string notation for Dial Sequences and GSTN /
Author(s) : C. Allocchio
Filename : draft-allocchio-gstn-03.txt
Date : 21-Mar-02
This memo describes the full set of notations needed to represent
in a text string a Dial Sequence. A Dial Sequence is normally
composed by Dual Tone Multi Frequency (DTMF) elements  plus
separators and the additional 'actions' (such as 'wait for
dialtone', 'pause for N secs', etc.) which could be needed to
successfully establish the connection with the target service:
this includes the cases where subaddresses or DTMF menu navigation
apply. Global Switched Telephone Numbers (GSTN) / E.164 addresses
(commonly called 'telephone numbers')  are a subset of a Dial
Sequence, and thus use the same set of notations.

exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
