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

[Ash]

Hi afshin,

I changed to the linux-image-rt (real time preemption patch) and so far the calls have been good.  A bulk of the calls will happen tomorrow so I will have more of and idea if it worked.  Looking at it now its set to 1000HZ so I hope this solves the issue.

Ash.

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.
