Example:
Max Channels may be used for PRIs that are provisioned for a lower number of channels.
High Channel, Low Channel and Search may be used for PRIs provisioned with specific
requirements for B-channel usage.
In the example above, the system will start searching for available B-channels at channel 20,
since Search is set to High and High Channel is set to 20. The system will not search for
channels below 10, since Low Channel is set to 10. Furthermore if the user tries to make an 8
channel call, the call will be established with 6 channels, since Max Channels is set to 6.
