Polycoms use "Groups" and "subscriptions" as you will see below when setting up paging below
The following override will create two page groups; page group 1 is "All Page" and page group 2 is "Sales." Devices that include these override settings will be able to send pages to these two groups.
ptt.pageMode.enable="1"
ptt.pageMode.group.1.label="All Page"
ptt.pageMode.group.2.label="Sales"
feature.nonVolatileRingerVolume.enabled="1"
np.normal.ringing.toneVolume.chassis="1000"
np.normal.alert.messageWaiting.tonePattern="silent"
In order to receive pages, individual devices must 'subscribe' to one or more page groups. The following override will allow devices to subscribe to the Sales group (group 2).
ptt.pageMode.group.2.subscribed="1"
The following override will allow devices to subscribe to both the Page All group (group 1) and the Sales group (group 2).
ptt.pageMode.group.1.subscribed="1"
ptt.pageMode.group.2.subscribed="1"
The default multicast IP address used by Polycom phones is 224.0.1.116/117. The default multicast port is 5001. Default values may be changed with the following override example:
ptt.address="224.0.1.117"
ptt.port="5003"
This can only affect the outbound address and not the listening addresses on the user, to help below are the standard ports that each group uses on the polycom system:
65322 = G1
65324 = G2
65326 = G3
65328 = G4
65330 = G5
65332 = G6
65334 = G7
and it continues to group 23 and in some devices goes higher in group count.
A user may produce up to 23 paging groups on a single network and as such the groups can only go up to 23. there is not a limit to the amount of users per group.
When a page is started the receiver will show the user who mage the announcement and the intended group receiver by the group name.
This by default is not picked up while the phone is "busy" however this can be changed in the GUI of the phone and overrides will not allow headsets or handsets to be used, it is only over speakerphone.
