Operational IP Phone Features
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
Aastra Web UI.
For incoming intercom calls, an administrator or user can configure the following
parameters:
