Call Commands

This Appendix provides detailed information on call commands for the
Cisco ATA 186.
There are several supplementary services that can be offered by a Service
Provider. Additionally, supplementary services can be activated, configured, or
deactivated in more than one way. The Cisco ATA 186 allows the behavior of
supplementary services to be defined using its "CallCmd" field.

Context Command Lists

The entry in the "CallCmd" field is a character string composed of a sequence of
instructions, called Context-Command-Lists. These Context-Command-Lists
each consist of a combination of three elements:
OL-1267-01
Context -- The Cisco ATA 186's supplementary service operation is
•
dependent upon a state- transition process. For example, the most common
state is IDLE, in which the Cisco ATA 186 is on-hook, waiting for an
incoming call. Picking up the telephone handset causes the Cisco ATA 186
to transition to the PREDIAL state, in which the user hears a dial tone and
the Cisco ATA 186 is waiting for DTMF digits to be entered. The Context
portion of the Context-Command-List specifies the state for which the
following commands are defined. The complete default state-transition
sequence is shown in.
Input-Sequence -- The input sequence is simply the input from the user, a
•
combination of hook-flash and DTMF digits.
