The CallCmd string has the following structure:
Context-Identifier Command . . . Command; . . . Context-Identifier Command;
•
•
Each Context-Identifier is followed by one or more commands to allow a variable number of actions to
be triggered by relevant user input commands for any state. Each command is composed of an
Input-Sequence that the user enters when the Cisco ATA is in a given state and two Action-Identifier
characters which define the action that the Cisco ATA performs in response to the Context-Identifier and
Input-Sequence. If the Cisco ATA takes only one action, one of the two Action-Identifier characters is
a null action.
Example 6-1
Af;AH;
In this simple example, the first "A" is the Context-Identifier, which means the Cisco ATA is in the
CONFERENCE state, as shown in

identifiers mean "NONE" and "Disconnect the call," respectively, as shown in
action identifiers, the Cisco ATA disconnects the most recent callee, and remains connected to the first
party. The state of the Cisco ATA becomes CONNECTED.

Example 6-2
CN;CAf;OF;
In this example, the first "C" is the Context Identifier, which means the Cisco ATA is in the
PREDIAL_HOLDING state, as shown in
