Transfer/Conference Call Behavior
If you are dialing the phone to transfer or conference a call, and your phone
receives an incoming call, your dialing is never interrupted (regardless of whether
the "Incoming Call Interrupts Dialing" is enabled or disabled). For Transfer and
Conference, the incoming calls always go to an available line (other than the one
you are using for dialing) and the incoming call's line LED blinks. The LCD still
displays your dialing screen.
Intercom Behavior
If "Incoming Call Interrupts Dialing" (Web UI) or "incoming call cancels
dialing" (config file) is enabled and you are dialing an outgoing Intercom call, the
enabled interrupt setting takes precedence over an enabled "Allow Barge In"
setting. The incoming call interrupts your dialing on an outgoing intercom call.
On an incoming intercom call, the enabled "Allow Barge In" and
"Auto-Answer" occurs while you are dialing to transfer or conference the call.
However, the incoming call goes to an available idle line, and the LED blinks
while you are dialing the second half of the conference or transfer.
If "Incoming Call Interrupts Dialing" (Web UI) or "incoming call cancels
dialing" (config file) is disabled, an incoming intercom goes to an available idle
line and the LED blinks for that line. The phone answers the call under all
conditions.
Configuring Incoming Call Interrupts Dialing
Use the following procedures to configure how the IP phone handles incoming
calls that interrupt outgoing dialing.
Configuration Files
