This might not be the same issue, but as an additional data point, I can
reliably generate audio drop-outs under revision 10725 as follows - it sounds
somewhat like a jittery network connection, with occasional glitches. Network
problems are not involved, though, as the phone and the machine running
FreeSWITCH are both on my desk, connected via my ADSL router.

On a Snom 320 SIP phone, select G.722 as the first codec.

Call extension 3001 in the default context of the supplied FreeSWITCH
configuration, with nobody else calling into the conference, and listen to the
resulting audio.

Changing the packet size from 20ms to 30ms in the phone's configuration and
repeating the test gave me the same result.

When I recompile FreeSWITCH and re-install, I'll test this again and post a
follow-up if the problem persists.
