Configuration Files
aastra.cfg, <model>.cfg, <mac>.cfg
Description Enable or disables how the phone handles incoming intercom calls while the phone is on
an active call.
When you enable this parameter (1 = enable), 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), and there is an active call, the phone treats
an incoming intercom call like a normal call and plays the call warning tone.
Note:
After enabling or disabling this feature, it takes affect on the phone immediately.
Format Boolean
Default Value 1 (true)
Range 0 (false)
1 (true)
Example sip intercom allow barge in: 0
