Shared Line
Yealink phones support Shared Call Appearance (SCA) and Bridged Line Appearance (BLA) to share a line.
Shared call appearances and bridged line appearances are similar signaling methods that enable more than one
phone to share the same line or registration. The methods you use vary with the SIP server you are using.
The shared line users have the ability to do the following:
l Place and answer calls
l Place a call on hold
l Retrieve a held call remotely
l Barge in an active call (only SCA)
l Pull a shared call (only SCA)
