Multicast Paging on Polycom Phones

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 can 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"

Individual devices must 'subscribe' to one or more page groups to receive pages. 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"
