Multicast Page Groups
A paging group is a multicast group that every phone, on the same LAN, that has joined the group can send audio to
and receive audio from the group. A multicast group is defined with a multicast address. Each OBi1000 phone supports
two multicast groups that are configurable by the admin. The admin may also assign a feature key for users to join or
leave each group. The default settings on the OBi work in most LAN environments, so usually all that is required is for
the feature to be enabled and a feature key mapped to each phone for the service. Push to talk can also be enabled for
Page Groups
–
this can be configured under
Phone Settings
::
Page Group 1/2
. Consult your phone administrator if to
see if the group paging feature is enabled at your location.
Here is how to use a group paging feature key:
1.
If not joined (LED off), press the key once to join. Once you joined, LED is red and your phone will play audio
received from the multicast channel
2.
After joining (LED red), press and hold down the key to talk (PTT or push-to-talk) to the group. Audio received
from the multicast channel is paused while you are talking
3.
If clamp-on option is enabled by the admin, you can enable clamp-on so that you can continue to talk without
needing to keep pressing down the key. To enable clamp-on, after joining, press and release the key quickly
and the LED will change to blink slowing in red to indicate clamp-on enabled
4.
To leave the group after joining (and clamp-on, if available), press and release the key quickly
