8028 SIP Doorphone (G2) FW 3.2
Basic Settings Tab – Multicast
Multicast IP Addresses
Each 8028 SIP Doorphone has its own IP address, and shares a common multicast IP
and port number (multicast zone) for multicast packets. The 8028 is able to act as a
multicast Slave, allowing it to receive multicast messages (i.e. one-way audio) from a
Master device and play it over the intercom speaker.
Note: The 8028 is not meant for voice paging in large areas. Instead we
recommend using the 8186 SIP Horn Speaker for outdoor or wide-area
applications, and the 8180 SIP Audio Alerter or 8188 SIP Ceiling Speaker for
any other indoor paging requirements.
The network switches and router see the packet and deliver it to all the members of the
group. The multicast IP and port number must be the same on all the master and slave
units of one group. The user may define multiple zones by picking different multicast IP
addresses and/or port numbers.
1. Multicast IP addresses range: 224.0.0.0/4 (from 224.0.0.0 to 239.255.255.255)
2. Port numbers range: 1 to 65535
3. By default, the 8028 SIP Doorphone is set to use the multicast IP address
224.0.2.60 and the port numbers 50000-50008
Make sure that the multicast IP address and port number do not conflict with other
services and devices on the same network.
Multicast Page Zones
The 8028 SIP Doorphone supports nine “basic” multicast zones. These zones are defined
by the multicast IP addresses.
Somewhat arbitrarily, these zones are defined below but may be used in other ways. The
important consideration is that there is a priority hierarchy – streaming activity on a zone
higher on the list, will be treated as a higher priority than a zone lower on the list – with
music being the lowest priority.
Priority

Zone 1
Zone 2
Zone 3
Zone 4
