Bridged Line Appearance (BLA)
BLA allows users to share a SIP line on two or more IP phones. Users can monitor the specific
extension (BLA number) 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. BLA
depends on support from a SIP server.
In the following figure, the first line is private and the second line is shared:
Any IP phone can be used to originate or receive calls on the bridged line. An incoming call to
the BLA number can be presented to multiple phones in the group simultaneously. The
incoming call can be answered on any IP phone of the group but not all.
Configuring BLA Feature on the IP Phone
You can share a BLA number on two or more phones. For example, phone A registers the
account 14019833020 and assigns BLA number, phone B registers the account 10462190020
and assigns BLA number, phone C registers the account 14755608020. Phone A and phone B
share the BLA number 14084588327.
