|
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.
