Audio Problems / How does "PBX delivers Audio" behave if set on Trunk vs User

[Marco4729]

Hi Everyone

We are having some irregular audio issues and are wondering what we can do to further analyze the problem.
At the moment we have everywhere the Option "PBX delivers Audio" set and a rule on the Firewall for QoS.

Does someone know how the Option "PBX delivers Audio" behaves if it's set on the SIP Trunk, but then would be disabled on the User itself? Does it completely override the rule? In your experience what are the best settings for good audio quality?

Thank you so much for the help, we are new to 3cx.

Marco

Trunk is generally left enabled, as a default, extension is enabled, if/as needed.
