Auto-Answer when Caller Requests to Barge-In (with OBiTALK Service)
In this scenario, the caller requests the called phone to auto-answer in order to join (or barge-in) an active call currently
on the called phone. Many soft switches offer this feature to the user by performing the audio mixing at the server end
without the phone knowing anything about the operation.
With proprietary signaling the OBi1000 on the other hand offers the Barge-In feature also at the device end with the
OBiTALK service (that is available to OBi-to-OBi calls only). The calling phone will request to barge-in when the user
dials a star code to enable the star code variable
$barge-in1
before dialing the target OBi number. The following star
code setup example uses *98 for this purpose:
*98, Barge In, set($barge-in1,1)
The called phone will automatically answer and conference in the calling phone, subjecting to resources available at
that moment. Note that the barge-in operation is only applicable if there is at least one active call on the called phone;
otherwise the incoming call to barge-in will be rejected.
Barge-In as a Coach
The calling phone to barge in may in addition request to coach the called phone instead of fully participate in the active
call. The calling peer that barges in is known as the
Coach
, while the called peer is known as the
Coachee
. The original
peer at the other end of the active call that the cocahee has been talking to is referred to as the
Patron
. Precisely,
coaching means: The coach hears a mix of the cocachee and patron speeches, the coachee hears a mix of the coach and
patron speeches, but the the patron hears only the coachee. To request to coach the called peer, the coach dials a star
code to enable the star code variable
$coach1
before dialing the coachee OBi number. The following star code setup
example uses *99 for this purpose:
*99, Barge In, set($coach1,1)
Note that this feature is also known as ‘Whispering” In some lite
rature.
Push To Talk
The phone supports push-to-talk mode with the feature key function Speed Dial, Busy Lamp Field, and Page Group 1
and 2. See the corresponding feature key section on how to enable the PTT mode with each function.
Speed Dial Feature Key
The phone administrator may allocate one or more feature keys on the phone to be used as Speed Dials. To find out
which feature keys are set up as Speed Dials, you can:
-
For a VLK, check the function icon on the respective VLKW on the display
-
For any feature key, press and hold down the key until the respective feature key item is shown on the display.
Then check the function icon of the feature key item.
Note that only the administrator can designate the function for each feature key. The user is not able to change the
function of a feature key as assigned by the admin. The user can however configure the
Number
and
Service
parameter of a speed dial feature key from the phone. The user can press and hold down the key until the
corresponding feature key item is shown on the display and then enter view or change the target number and the
service (a.k.a. line) to use when calling from that speed dial key. To call from a speed dial key, simply press and release
the feature key normally.
o
To enable the PTT mode on a speed dial, the administrator must include the ptt flag in the Number parameter of
the speed dial.
The general syntax is
Number
= {
target-number
}[
;ptt
][
;send=
{
digit-codes
}] where {
target-number
} can be an
empty value if the number is unassigned, and {
digit-codes
} is a sequence of the following case-sensitve codes:
▪
0-9,*,#,a,b,c,d
–
The DTMF digit to send to the peer. Each digit is sent with 100 ms on and 100 ms off
▪
S
–
Pause for 3s
