Call Command Behavior
3WAYCALLING: Cisco ATA is
connected to two far end users on the
same line; one of them is in active
conversation (the active far end or AFE)
while the other is on-hold (the waiting far
end or WFE). This state is initially
entered when the CiscoATA is connected
to one of the far ends, then places this far
end on hold and calls the second far end.
United States:
•R—Retrieve the WFE and go to CONFERENCE state.
•ONH—Transfer the WFE to the AFE, drop out of the call, and go to
PREDIAL state.
Sweden:
•Same as for CALLWAITING state
CONFERENCE: CiscoATA is connected
to two active far ends simultaneously;
CiscoATA performs audio mixing such
that every party can hear the other two
parties but not themselves.
United States:
•R—Disconnect the last callee and stay connected with the first party, and
revert to CONNECTED state.
Sweden:
•R4—Transfer one FE to the other, drop out of the call, and go to PREDIAL
state.
PREDIAL_HOLDING: CiscoATA user
places a connected call on-hold and
prepares to dial a second number;

complete dialing a second phone number.

entering a configuration command.
