Chapter 11: Board Configuration
126 MaxCS 7.5 Administration Manual
Notes :
• Make sure you have enough VoIP resource boards.
• The more signal channels, the more system memory and CPU power required. Proper planning is
essential.
• Changing the number of signal channels requires that you stop and restart the switching and gateway
services.
• SIP Trunking Channel requires a license to activate.
Configuring the SIPSP Board
Double-clicking a SIPSP board in Boards view and then clicking the Board Configuration button opens the
SIP Signaling Channel Configuration dialog box, which shows the number of configured channels and licensed
channels.
Figure 73. The SIP Signalling Channel Configuration panel
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 chan-
nels 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.
Note: If you change the number of SIP extension or tie trunk channels, you must stop and restart the
switching and gateway services.
The SIP Trunking Configuration button opens the SIP Trunking Configuration dialog box. (See “SIP Trunk
Properties” on page 142.)
