Bridged Line Appearance (BLA)
(480i/480i CT/9133i only)
A SIP bridge line appearance
(BLA) on the IP phones allows
multiple devices to share a single
directory address (DA).
For example, people working at a
technical support department
could be located in different
places. If their desktop phones are
configured for BLA DA, when
customer calls come in, all the
to save your
phones with the BLA DA would
ring but the call can only be
answered by one of them.
Once the call is answered, the rest
of the phones reflect the status of
the call. If the call was put on
"hold" by the original recipient,
any one from the group can pick
up the call.
Note: 1. This feature is dependent on
the IP telephony system to which
the IP phone is registered and
according to
bla-02.txt.
2. Interactive Intelligence and
Sylantro servers support the sin-
gle BLA group with single line
appearance feature only.
You can apply BLA on the IP
phones as follows:
• As a single BLA group - One
BLA DA is shared among multi-
ple phones. Only one phone at a
time can pick up an incoming
call or initiate an outgoing call
on the BLA DA. All phones
reflect the usage of the BLA DA.
If the call is put on "hold", any
one from the group can pick up
the "held" call.
• As a multiple BLA group - On
one single phone, multiple BLA
DA can be associated with dif-
ferent line appearances. Every
BLA DA is independent from
each other and follows the same
rules as "a single BLA group".
• As multiple instances of a BLA
DA - A "x-line-id" parameter
was defined in
ping-bla-02.txt
incoming call to or place an out-
going call on the specified line
appearance instance. The
parameter is carried in "Alert-
Info" header field over the
request-URI (INVITE e.g.) or in
the NOTIFY messages to report
the status of a dialog.
