When an IP phone registers to the system, a channel ID will be assigned to the IP extension. However, these
channels are only responsible for processing protocol and call control signals. They require a media path from
a VoIP board or from the IP phone to establish a voice steam so that both sides can hear.
Notes
• Make sure you have enough VoIP resource boards.
• The more signal channels in the system, the more system memory and CPU power is required.
• Changing the number of signal channels requires that you restart the switching and gateway services.
• SIP Trunking Channel requires a license to activate.
To configure the SIPSP board,
1. In MAXCS Administrator, open the Boards panel and double-click SIPSP.
2. Click Board Configuration. The SIP Signaling Channel Configuration panel opens. This panel shows
the number of configured channels and licensed channels.
3. Adjust the number of SIP extension channels and Tie-Trunk channels as needed.
By default, MAXCS is set to support 60 SIP extension 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.
4. After you adjust these values, you must restart the switching and gateway services for this change to
take effect. After the services restart, the new configuration will appear in the Currently Configured
Channels fields.
