'''
This application, in conjuction with it's rule file (rules.py) will
work like a "conference bridge". This is similar to what most hams think of as a
reflector. You define conference bridges and any system joined to that conference
bridge will both receive traffic from, and send traffic to any other system
joined to the same conference bridge. It does not provide end-to-end connectivity
as each end system must individually be joined to a conference bridge (a name
you create in the configuraiton file) to pass traffic.

This program currently only works with group voice calls.
