[Freeswitch-users] FS SIP audio quality?

[Paul D.]

Comparing FS 1.0.3 audio quality vs * 1.4.2, simple Sip-to-Sip call, or 
call to VM prompt, or call via  gateway to PSTN - FS audio volume level 
(should I say gain?) seems noticeably lower than on *, this may be a 
reason that FS audio seems to be subpar, more noise less clear. Test 
calls made using PCMU codec from X-Lite and Linksys 2002.
Is there anything can be tweaked in FS to correct that? Same issue was 
with 1.0.2.
