Conference not available while pressing "Confrn" soft key
We've a cluster with several users but one site complaints they get error message "Conference not available" while trying to make a Conference call. There're 4 software conference bridges and 1 hardware conference bridge. SoftwareBridge should take preference per MRG. Below is the trace for failure.

I will seperate sw conf bridge from hw conference bridge.
In a MRG there are no preferences, devices are selected on a round robin fashion. You will never know which conference bridge the call is going to use.
It is good practice to have software conference bridge in a seperate MRG from hardware conference bridge MRG. Then assign software cnf bridge only to devices that do G711 and you can then assign Hardware conferenc bridge to devices that do a mix of G729 and g711.
Software conf bridge does not support G729. If any of the devices are using G729 and software coonference bridge is selected, then the conf will fail
