Broadsoft Shared Call Appearance
This new feature makes the phone compatible with Broadsoft Shared Call
Appearance facility.
This function allows several users to share a phone number (the one in the
active SIP profile), so that they can receive the same calls, make a call from
the same number, unhold a previously held call, or even conference.
For incoming calls, all the phones with this service active (SCAs from now
on) will ring simultaneously and the first picking up will catch the call.
For outgoing, the SCA will take the line, if available, by sending a
subscription and the caller number is the same independent of which SCA is
doing the call.
In order to support this, the phone establishes 2 new kind of subscriptions:
event=line-seize and event=call-info. The first is for taking the (shared) line
and the second to be informed about the status of this (shared) line: idle,
seized, progressing, active, held, held-private, bridged-active and bridge-
held.
Enriched Display
A new screen and some softkeys are available specifically for this feature.
The screen shows the status of the shared line: as soon as there is an active
call in any of the phones using the same Shared Call Appearance (SCAs), it
will be launched in the rest of them and refreshed when any change in the
state of this call occurs.
The softkeys are:
"Retriv": retrieve selected call appearance which is in Held state.
"BargIn": barge in selected call appearance which is in Active/Bridge-
Active/Brideg-Held state. After that, we‟ll have a 3-way call between the
initial shared call appearance, the phone which did the Barg-In and the
remote party.
"NewCal": make a new call
"Back": cancel the display of call appearance(S) state and back to previous
state.
Feature activation
To activate Shared Call Appearance user just have to click on the SCA flag in Advanced->Call
feature menu in the Web GUI:
Or by APS in [sip] section of both Common or Specific-MAC config files with the new
parameter SharedCallAppearance (0 by default, inactive; 1 to active):
[sip]
...
SharedCallAppearance=1
...
The rest of the configuration will be done by your BroadSoft accounts administrator.
