Media Path – Encodes, transmits, and decodes voice for both parties. 
The purpose of the virtual board SIPSP is to build signal channels for different connection types, IP extensions, 
SIP Tie Trunks, and SIP Trunking from ITSP. Each channel will have its channel ID similar to channels on a 
Triton extension or trunk board.  
When an IP phone registers to the system, a channel ID will be assigned to the IP extension. However, these...

3. Adjust the number of SIP Extension channels, Tie-Trunk, and SIP 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 you are using a high performance machine as the Softswitch server, the number of channels can be 
more than 1000.  
Make sure that the system has enough voice processing resources. Calls...
