Configuring VoIP Support
• H.323 Signaling/Media inactivity time out (seconds) - This field has a default value of
300 seconds (5 minutes). This is a similar setting to the “TCP connection inactivity timeout.”
• Default WAN/DMZ Gatekeeper IP Address - This field has a default value of 0.0.0.0. Enter the
default H.323 Gatekeeper IP address in this field to allow LAN-based H.323 devices ti “discover”
the gatekeeper using the multicast address 224.0.1.41. If you do not enter an IP address, multicast
discovery messages from LAN-based H.323 devices will go through the configured multicast
handling.
