On a locally-mixed N-way call, user can selectively mute any of the call legs (i.e. no audio sent to the call peer only),
using the
Mute
softkey on the highlighted call on the screen. The
Mute
softkey can be enabled for the
CallConnected
and
CallConnecting
soft key sets.
Coachee Mode
On a locally-mixed N-way call, user can select one of the call legs to be her coach using the
Coachee
softkey (i.e.,
the user herself will become the coachee to the peer on that call leg). In coachee mode, the audio of the coach is NOT
mixed into the audio sent to the other call peers of the N-way call; the coach audio is only added to the mix to the local
user, the coachee. The audio mix to the Coach on the other hand includes all the other parties. The
Coachee
soft
key can be enabled for the
CallConnected
and
CallConnecting
soft key sets. For the cocahee, the call item on the
screen can show an icon to indicate if a call-leg is currently in coachee mode. The coach on the other hand has no
knowledge of her role as the coach unless the the call is on OBiTALK service. In that case, the coach
’s phone
can also
show a Coach icon in the call item to indicate its special role in that call.
External Conference Bridge
(SIP/SP Only.) When using an external conference bridge, the conference size is not limited by the phone but by the
conference bridge. Check with your conference service provider on the conference size limit. Again you can start a 3-
way conference as described earlier. In this case the phone first sends a new INVITE to the SIP URL of the conference
bridge to request the conference resources. If successful, the conference bridge replies a 2xx response with a Contact
header that includes the context information for other conferees to access the bridge for this conference call. On that
the phone maintains the call with the bridge in the Connected State and sends a REFER to both conferees to refer them
to the Contact as referenced by the conference bridge. The phone user will then notice that only one connected call to
the conference bridge remains on the screen while the two calls with the initial two conferees are removed.
Presumably the two conferees have also connected to the conference bridge on their own.
To add another conferee, make a new call to the target number (or answer a new incoming call from another party, if
applicable), which automatically holds the call to the conference bridge. When the called target rings or answers,
highlight the call with the conference bridge (currently in the Holding State) and select the
Add to Conf
soft-key
option. At that point the call to the conference bridge is resumed while the new remote party is (or will be if it is still
ringing) referred by the phone to the same conference bridge Contact (as soon as it answers) to be added to the
conference bridge. You can continue to add more conferees this way until it reaches the limit set by the conference
bridge.
To enable external conference bridge operation, insert the rule
{cbridge:sp1(conference)}
in
Phone
Settings
::
OutboundCallRoute
and also enable the option

::

Features
::

. It should be noted that the phone assumes that only conferees that are
on the same SP service or using the same ITSP profile as the conference bridge can be referred to the bridge. For
conferees that are referable, the phone keeps them in the conference using local mixing and will be subject to the local
mixing limit. For example if you have a conferee that is connected through the OBiBluetooth service, the phone keeps
the call with that conferee in the Connected State as well as the call to the conference bridge in the Connected State
and applies local mixing to the two calls.
No Hold Call (NOHC)
This feature allows the user to start a new call while having one or more active calls without placing other calls on hold
first. Hence the current call peers will not notice if any state changes (and could continue to talk without any
interruption). User starts a
no hold call
by pressing the NOHC softkey, which may be enabled for the
CallConnected
soft key set.
Expanded Call Features
Expanded call features go beyond the basics to provide additional features for enhanced productivity and control.
Unless noted otherwise, the features described here can be performed by the phone independent of a soft switch.
