Note that when audio is received from the group, all your current calls will be interrupted in the standard way as if a
new foreground call is added. When joining two groups, the audio from the two groups are mixed by the phone when
received at the same time. The phone can mix up to two RTP streams in each page group.
Music On Hold (MOH)
The OBi1000 series have native support of MOH. You may configure a MOH server in the parameter

Calling Features
::
MOHServiceNumber
. The MOH Server number can be an external SIP or OBiTALK addressable
device, such as pp(ob600559558) or sp3(moh-server). The expected behavior of the MOH Server device is such that
when called, it automatically answers the call and starts streaming audio to the calling device.
The OBi1000 has a built-in MOH Server that can be invoked by specifying:
an(
{prompt}
)
(where an stands for the
internal announcement server), and prompt is a specification of the source to play. The devices includes a Jazz track
that can be used for music on hold. To enable the built-in track, specify the MOHServiceNumber as
an(jazz)
Premium Call Features
Busy Lamp Field (BLF)
(SIP/SP only.) BLF is a common collaborative feature for a user to monitor the extensions of other users from their
phone. BLF is a feature of the monitoring phone, The monitored extension usually does not do anything special to be
monitored. The detection and notification of events occurring at the monitored extensions are carried out by the soft-
switch.
When BLF is supported by a specific SP service on the OBi1000, the BLF function can be assigned to a feature key bound
to that service to monitor an extension in the context of that SP service (That is another extension on the same hosted
voice service or PABX system). We refer to a feature key that is assigned the BLF function as a BLF key. One BLF Key
monitors one extension only. The administrator can assign as many BLF Keys as there are feature keys available, to
monitor as many extensions. The following table lists the typical events that are monitored with a BLF Key. The table
also shows the operation that can be invoked when the respective event occurs, and the LED pattern indicating that
particular event.
