Settings
IP multicast addresses are used by the Spectralink 8030 Handset when Push-to-talk
(PTT) is enabled. If PTT is in use, multicasting must be enabled on the subnet used
for the Spectralink 80-Series Handsets, SVP Server, and Telephony Gateways.
Routers are typically configured with filters to prevent multicast traffic from flowing
outside of specific domains. The wireless LAN can be placed on a separate virtual
LAN (VLAN) or subnet to reduce the effects of broadcast and multicast traffic from
devices in other network segments.
