INITIAL BRANCH COMMIT 0) CONFIGURATION FILES WILL NEED UPDATED TO CHANGE NAMING CONFIGURATIONS! 1) Updated use of socket address instead of discrete IP/port. This will be needed for socket address based validation and is faster… duh… should have done this in the beginning. 2) Changed all references to “clients” as HBP systems to “peers”. This sets the stage for having a peer_id and an originator_id for DMRD packets. 3) Found and squashed a number of other random bugs, including the registration ACL not working in confbridge or bridge_all. 4) router is now retired. confbridge is the future.

'''
This application, in conjuction with it's rule file (hb_confbridge_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.

INITIAL BRANCH COMMIT 0) CONFIGURATION FILES WILL NEED UPDATED TO CHANGE NAMING CONFIGURATIONS! 1) Updated use of socket address instead of discrete IP/port. This will be needed for socket address based validation and is faster… duh… should have done this in the beginning. 2) Changed all references to “clients” as HBP systems to “peers”. This sets the stage for having a peer_id and an originator_id for DMRD packets. 3) Found and squashed a number of other random bugs, including the registration ACL not working in confbridge or bridge_all. 4) router is now retired. confbridge is the future.

INITIAL BRANCH COMMIT 0) CONFIGURATION FILES WILL NEED UPDATED TO CHANGE NAMING CONFIGURATIONS! 1) Updated use of socket address instead of discrete IP/port. This will be needed for socket address based validation and is faster… duh… should have done this in the beginning. 2) Changed all references to “clients” as HBP systems to “peers”. This sets the stage for having a peer_id and an originator_id for DMRD packets. 3) Found and squashed a number of other random bugs, including the registration ACL not working in confbridge or bridge_all. 4) router is now retired. confbridge is the future.
