[Freeswitch-users] No audio for 3 seconds on some calls

[Ash]

I think I may have solved my own problem... I am running on Ubuntu (I know its not recommended) and my kernel timer was set to 100hz.  Running time_test 1000 1000 it would avg from 997 to 1300 when I kept running it.  I have now set the kernel to be 1000hz and it now avg around 1008-1014 on multiple tests.

Unfortunately its not one of those always happens issues so I will have to see how it goes.
