[Freeswitch-users] Static and Scratchy Audio

[James Mortensen]

Hey Anthony,

We are trying using PCMU only and will run more tests.  But one thing we're
confused on about opus is that we haven't changed anything since we
initially set this up weeks ago.  So assuming we didn't change anything,
and this is all **locally running** code, how would OPUS be causing a
problem here?

Thanks for your help!


James
