The virtual channel definitions make it easy to work with the different signals
since each virtual channel has a specific name and refers to a particular input
or output. For instance to take the phone off hook, commands are sent to the
"770-350-4400" virtual channel in this example. If there were multiple
telephony interfaces, each telephony interface would have its own unique
virtual channel definition. It is possible to create a logical group of multiple
telephony virtual channels so all systems could be put onhook together at the
end of a call, etc.
In this example there are several logical groups defined including "Reinforced
Mics", "All Mics", "All Table Mics", "Program Audio", "Remote Receive
Audio", and "Remote Send Audio".
