Some routers and gateways are configured for what is commonly called „Broadcast storm protection‟ which has a
limit for bandwidth of a broadcast from any source. The primary benefit of such a feature is to prevent a Denial of
Service attack on the network. Once the limit is exceeded, the router will stop the broadcast. This might occur
during an All Call or Group Call event. If you suspect a limit is shutting down the All Call or Group Call, set the
bandwidth for the IPW-1A and the CommuniCenter software to the Low setting and verify that each IPW-1A has its
own unique ID # and try All Call or Group Call again. If the broadcast is still getting blocked, find out what is
blocking it using a packet analyzer tool.
