The recipient can drop the incoming page if required. The recipient can also press Do Not

Disturb (DND) or other “ignore” options on the device to ignore/reject any incoming pages.

3.2 Caveats of Multicast Paging

Multicast paging is supported on ZIP5/ZIP3 phones only. There is no guaranteed interoperability

with any other Zultys-supported phones. CyberData Paging Equipment is an exception, as it has

been tested and certified to work properly with the ZIP5/ZIP3 phones. The ZIP2xN phones and

MXIE Softphone does not support multicast paging. The 57iCT cordless handset cannot initiate a

multicast page.

This service is typically non-routable, and cannot be used to page across the MXnetwork or to

remote devices.

Note: The Group Paging Settings are dependent on the setting for the “Allow Barge In”

parameter.

Note: Multicast page is one-way only - from sender to the receiver.

Note: For outgoing pages, all other existing calls on the phone are put on hold.

For incoming pages, the ringing display is dependent on the “Allow Barge In” parameter. If this

parameter is disabled, and there is no other call on the phone, then the paging is automatically

played via the preferred audio device.

If there is an existing call on the phone, the call initially displays in the ringing state. The user has

the option to accept/ignore the call. If the “Allow Barge In” parameter is enabled, the page call

barges in, and any existing calls are put on hold.

If a page session already exists on the phone, and the phone receives another incoming page, the

priority is given to the first multicast session and the second multicast session is ignored. The

behavior for the incoming calls in this case is also based on the setting for the “Allow Barge In”

parameter. The incoming call is handled as if there were an existing call already on the phone.

3.3 Advantages of Multicast Paging

Multicast paging allows for virtually unlimited paging capability in a local network, does not

require a session license to operate, and is almost instantaneous, as it does not require the

phones to acknowledge the page request.

Multicast paging is a certified option to increase the number of devices in a page zone from 32

phones on an MX 250 or 16 phones on a MX30 to a virtually unlimited number.
