Call Forward Signaling
If the called service is on SP
m
and the call forward target is on SP
n
where SP
m
and SP
n
point to the same ITSP Profile
X
(including the case
m
=
n
) and
ITSP Profile X – General
::
SignalingProtocol
is SIP and
ITSP Profile X –
SIP
::
X_Use302ForCallForward
is
true
, the phone will attempt to forward the caller by replying a 302 response to
the INVITE request with the forward target’s SIP URL in a Contact header. For other cases, the phone will try to bridge
the caller and forward target internally.
Limitations of Call Froward by Internal Bridging
The phone acts as a proxy of RTP packets sent by each peer of the bridge, without any transcoding. While the phone
will try its best to negotiate the codec to use with each call peer that would be acceptable by the other peer, the
administrator should understand this limitation and configure the codec profiles accordingly. For example, if Google
Voice is to be used, then a call forward involving a Google Voice call leg must make sure the other call leg supports
G711U codec.
Do Not Disturb
Do Not Disturb (DND) allows you to set the phone to immediately forward calls made to your OBi to the number set-up
as your voicemail number / account. If no voicemail account is set-up, the OBi will return a busy signal to the caller
until you turn off DND. To turn on DND, from a phone attached to the OBi, dial *78. To turn off DND, from a phone
attached to your OBi, dial *79.

Do Not Ring
Enabling Do Not Ring disables the ringer – this is equivalent to silent mode. The phone screen will still indicate when a
call is incoming. A feature key can be assigned with the corresponding LED indicating the Do Not Ring on/off status.
Message Waiting Indication – Visual and Tone Based
(SIP/SP Only.) Message Waiting Indication notifies the user when a new voice message is available. The OBi supports
both Visual and Tone based Message Waiting Indication. With Tone-based Message Waiting Indication, the user is
alerted to a waiting message by a “stutter” dial playing when the phone is taken off-hook. Typically, this stutter tone
will be removed once the user listens to the message(s). Visual-based Message Waiting Indication will turn on a light
and show a voicemail icon on the screen when there is a message waiting.
