[Freeswitch-users] Audio quality

[Alex Balashov]

I don’t think anyone can be sure of what is causing the issue. But you can make some effort to isolate it; does this happen with all callers? Does all your origination come from the same place (e.g. carrier)? Can you test a different origination provider and see if you get the same issue?

That’s a good way to figure out if it seems to be related to the system itself or to the network path to the caller.
