I have a pub and subscriber running 7.1.3 and configued two conference bridges. They started out working but now do not. When I am the first call I press the conf button on the phone, dial the second number. I get the other party on the phone and then go and press the conf button again to bridge them together and everyone gets a busy signal.
This is with internal calls and external calls.
Do I need to have a conference bridge for each device pool?
