Configuring Virtual Board HMCP
MAXCS is set by default to support 60 SIP extension channels. You can change the
number of SIP extension channels and tie-trunk channels. The maximum number
possible depends of the system CPU performance, call volume, and usage. If a high
performance machine is used as the Softswitch server, the number of channels can be
more than 1000. If you change the numbers in this dialog box, you must shut down and
restart the switching and gateway services for this change to take effect. When the
services restart, the new configuration appears in the Currently Configured Channels
fields.
The SIP Trunking Configuration button opens the SIP Trunking Configuration dialog
box. (See "SIP Trunk Properties" on page 122.)
Configuring the H323SP Board
Double-clicking an H323SP board in Boards view and then clicking the Board
Configuration button opens this dialog box:
Figure 86. 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.
