Figure 74. H323 Configuration
You can change the following parameters:
• FastStart Enabled: The FastStart Enabled option reduces the number of H.323
messages to be sent between two H.323 devices when initiating a call, thus reducing
the time needed to establish a call. There may be a compatibility issue with firewall
or NAT devices, if you select this option.
• Max Tie-Trunk Channel: Sets the maximum number of trunk channels for this
board in increments of 4, from 4 to 96. You need to reboot the MAXCS system after
the maximum trunk channel number is changed.
