Intercom Barging
2-digit number and a *. To dial + from keypad, press on 0 until + appears
on LCD.
Example of a simple dial plan used in a Home/Office in the US:
{^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. |
[3469]11 }
Explanation of example rule (reading from left to right):
• ^1900x. – prevents dialing any number started with 1900
• <=1617>[2-9]xxxxxx – allow dialing to local area code (617) numbers
by dialing 7 numbers and 1617 area code will be added automatically
• 1[2-9]xx[2-9]xxxxxx |- allow dialing to any US/Canada Number with 11
digits' length
• 011[2-9]x. – allow international calls starting with 011
• [3469]11 – allow dialing special and emergency numbers 311, 411,
611 and 911
The dial plan supports also "T" character which means dial delay. This is
used with "No key entry timeout (s)".
For example, if the dialplan is set to {8001T}, when the user opens Phone
app and dials 8001, the phone would not call out immediately, but will
wait for the No key entry timeout to dial out.
Note: In some cases, where the user wishes to dial strings such as *123
to activate voice mail or other applications provided by their service
provider, the * should be predefined inside the dial plan feature. An
example dial plan will be: {*x+} which allows the user to dial * followed by
any length of numbers.

Configures whether to answer the incoming intercom call when there is
already an active call on the phone. When "Intercom Barging" is enabled,
if the current active call is an intercom call, the incoming intercom call will
be automatically rejected; if the current active call is not an intercom call,
the current active call will be put on hold and the incoming intercom call
will be automatically answered. When "Intercom Barging" is disabled, a
prompt will show up indicating the incoming intercom call without
interrupting the current active call.
The default setting is disabled.
