Hey Benny, >> I'm seeing 100% CPU usage right after PJSUA writes 'Jitter buffer reset' to >> the log. This only happens once in a while, that's why I couldn't reproduce >> it properly. When the JB is not reset, 480s are handled just fine, just like >> everything else. >> >> What can I do to find out why this is happening? Is this a known issue? >> Please help me out here :) >> > Yeah this was a known issue, sorry for that. The fix is in the trunk: > http://trac.pjsip.org/repos/ticket/762 No problem, I should have searched the mailing list and bug tracker better in the first place.
