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 virtual
channel 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 virtual channel groups defined including "Reinforced Mics", "All Mics", "All
Table Mics", "Program Audio", "Remote Receive Audio", and "Remote Send Audio".
