Mitel 6800i Series SIP Phone Release 4.1.0 Administrator Guide
"Delay" before Auto-Answer
The IP Phones include support for the "delay" parameter (in the Alert-Info header, used in
conjunction with info=alert-autoanswer) in order to facilitate auto-answer functionality. When
present, the value of the "delay" parameter specifies the length of time in seconds an IP phone
rings before a call is auto-answered. If this value of the "delay" parameter set to 0 (delay=0),
then an incoming call is immediately auto-answered. The absence of the parameter is
considered as ring forever.
In order for the delay functionality to operate, you must first enable Auto-Answer on the IP
Phone.
Allow Barge In
You can configure whether or not the IP phone allows an incoming intercom call to interrupt an
active call. The "sip intercom allow barge in" parameter controls this feature. When you
enable the sip intercom allow barge in parameter (1 = enable in the configuration files), which
is the default value, an incoming intercom call takes precedence over any active call, by placing
the active call on hold and automatically answering the intercom call. When you disable this
parameter (0 = disable in the configuration files), and there is an active call, the phone treats
an incoming intercom call like a normal call and plays the call warning tone. You can set this
parameter using the configuration files or the Mitel Web UI.
For incoming intercom calls, an administrator or user can configure the following parameters:
CONFIGURATION FILE PARAMETERS
sip allow auto answer
sip intercom mute mic

sip intercom allow barge in
Note: To configure incoming intercom calls using these parameters, see
