It is easy and convenient to use multicast function to send notice to each member of the multicast via
setting the multicast key on the device and sending multicast RTP stream to pre-configured multicast
address. By configuring monitoring multicast address on the device, monitor and play the RTP stream
which sent by the multicast address.
MCAST Settings
Equipment can be set up to monitor up to 10 different multicast addresses, used to receive the
multicast RTP stream sent by the multicast address.
Here are the ways to change equipment receiving multicast RTP stream processing mode in the Web
interface: set the ordinary priority and enable page priority.

Priority:
In the drop-down box to choose priority of ordinary calls the priority, if the priority of the incoming
flows of multicast RTP, lower precedence than the current common calls, device will automatically ignore
the group RTP stream. If the priority of the incoming flow of multicast RTP is higher than the current
common calls priority, device will automatically receive the group RTP stream, and keep the current
common calls in state. You can also choose to disable in the receiving threshold drop-down box, the device
will automatically ignore all local network multicast RTP stream.

The options are as follows:

1-10: To definite the priority of the common calls, 1 is the top level while 10 is the lowest

Disable: ignore all incoming multicast RTP stream

Enable the page priority:
Page priority determines the device how to deal with the new receiving multicast RTP stream
when it is in multicast session currently. When Page priority switch is enabled, the device will
automatically ignore the low priority multicast RTP stream but receive top-level priority multicast
RTP stream, and keep the current multicast session in state; If it is not enabled, the device will
automatically ignore all receiving multicast RTP stream.
