Shared Call Appearance (SCA) Configuration
In SCA scenario, an incoming call can be presented to multiple phones simultaneously. Any IP phone can be used
to originate or receive calls on the shared line.
Yealink phones support SCA using a SUBSCRIBE/NOTIFY mechanism as specified in RFC 3265. The events used
are:
l “call-info” for call appearance state notification.
l “line-seize” for the phone to ask to seize the line.
You have the option to provide users the ability to do the following:
l Configure a private hold soft key or Private Hold key and provide users the ability to hold a call privately.
l Configure a call pull code, which allows users to retrieve an existing call from another shared phone that is in an
active or public hold status.
