BLF Operation: Speed Dial
When used as a speed dial, the OBi1000 determines the number to call the monitored extension according to the
following logic, based on attributes specified in the Number parameter of the BLF key:
-
If the optional
spd
attribute is specified, call that attribute, else
-
If the optional
ext
attribute is specified, call that attribute, else
-
Call the {
userid
} attribute, which MUST be specified for a BLF key
BLF Operation: Directed Call Pickup
Directed Call Pickup can be done in one of two ways: a) Feature Code or b) Repleaces. The method to use is
configured under the ITSP Profile of the SP Service that is bound to the BLF key.
For the Feature Code method, the Feature Code to use for Directed Call Pickup is also configured under the same ITSP
Profile; the OBi1000 sends a normal INVITE to the number formed by concatenating the Feature Code with the number
of the monitored extension (the
ext
attribute of the
Number
parameter, if it exists or else the {
userid
} attribute).
(BroadSoft, FreePBX)
For the Replaces method, the OBi1000 sends an INVITE with a Replaces header that identifies to the soft-switch
the ringing call to pick up from the monitored extension. (MetaSwitch)
BLF Operation: Barge In
When the monitored extension is on a connected call, the monitoring phone may barge in to join the call, if the soft-
switch supports the operation and if the feature is enabled in the phone configuration. This operation requires the
specification of a barge-in feature code that can be configured under the ITSP Profile of the SP service that is bound to
the BLF key. To barge in, the OBi1000 sends a normal INVITE to the number formed by concatenating the barge-in
feature code with the number of the monitored extension (the
ext
attribute of the
Number
parameter, if exists or
else the {
userid
} attribute). (BroadSoft, FreePBX)
BLF Operation: Call Pickup
When a call is parked against the monitored extension, the monitoring phone can pick up the parked call by sending a
normal INVITE to the number formed by concatenating a call pickup feature code with the number of the monitored
extension (the
ext
attribute of the
Number
parameter, if exists or else the {
userid
} attribute). The call pickup feature
code can be configured under the ITSP Profile of the SP service that is bound to the BLF key. (BroadSoft)
BLF Operation: Resume
The Resume operation is intended to resume (and take over) a holding call on the monitored extension. At the time of
writing, there is no known soft-switch that supports this operation.
