I want test the pbx as “Intercom” where more peoples at the same time can calll the sip number digiting the password talking toghether around the country using mobile phones and computer sip clients to coordinate video cameraman operator in live television events.
For this test experimental purpose I need to pump the volume always at the maximum possible with a compressor (to avoid low volumes in ambients with urban noise and compressing it to avoid distorsions. For compression I mean not bandwitdth but audio compression to have a low volume automatically high)
How I can manage audio compression and volume to regulate it always at the maximum volume?
Also how I can set better volume quality?
