Call Command Behavior
RINGING: CiscoATA is ringing the
phone to alert user of an incoming call
•OFH—Stop ringing, answer the call, and go to CONNECTED state.
CONNECTED: The CiscoATA is
connected with one far end party;
Cisco ATA may be the caller or the callee
United States and Sweden:
•R—Hold current call, play dial-tone to dial second number, and go to
PREDIAL_HOLDING state.
WAITHOOK: Far end hangs up while in
CONNECTED state; Cisco ATA plays
fast-busy after five seconds in this state
•R—Stop fast-busy, start dial-tone, and go to PREDIAL state.
CONNECTED_ALERTING: CiscoATA
receives another call while in
CONNECTED state; Cisco ATA plays
Call Waiting tone periodically (every 10
seconds for US; every second for
Sweden)
United States:
•R—Place current call on-hold, answer the waiting call, and go to
CALLWAITING state.

CALL WAITING: CiscoATA is
connected to two far end users on the
same line; one is in active conversation
(the active far end or AFE) while the

far ends while the other far end calls into
the Cisco ATA.
