SHARED CALL APPEARANCE (SCA) CALL BRIDGING
Shared Call Appearance (SCA) is when incoming calls are presented to multiple phones
simultaneously. For example, it is the ability to assign the boss' extension to a button on the
secretary's phone. Calls can be transferred between two phones with the same extension button
by simply putting the call on hold at one phone and picking it up on the other. Status LEDs light
and flash in unison, allowing all people sharing the extension to see the status at a glance.
The IP Phones include an enhanced SCA for the servers that support call bridging and allows
two or more SCA users to be connected in a call with a third party.
Refer to the following example.
Notes:
1.
If you change the setting on this parameter, you must reboot the phone for it to
take affect.
2.
Both the “
sip explicit mwi subscription
” and “
sip mwi for bla account
”
parameters must be enabled in order for the MWI subscription for BLA to occur.
3.
The MWI re-subscription for the BLA account uses the value set for the "
sip
explicit mwi subscription period
" parameter to re-subscribe.
4.
Whether or not the "
sip mwi for bla account
" parameter is enabled, the priority
for displaying MWI does not change
