Bridge Lines Appearance (BLA)
BLA allows users to share a SIP line on two or more phones. Users can monitor the specific extension (BLA num-
ber) for status changes on each IP phone. To use this feature, a BLA group should be pre-configured on the server
and one of them is specified as a BLA number.
Yealink phones support BLA using a SUBSCRIBE/NOTIFY mechanism as specified in RFC 3265. The event used
is: “dialog” for bridged line appearance subscribe and notify.
