CentOS usually comes with the kernel timer set to 1000Hz, but if it has been set to 100Hz (eg because it is on a virtualised platform) then this can cause choppy sound with mismatched ptimes.  If it's not that, then I have no better ideas.

What operating system/platform are you using? Some people have problems with some Ubuntu kernels.

Hello,

 

I have a problem with one of my sip trunks. The provider uses g729 with a ptime of 40ms and all incoming calls that are being recorded or go to the conference have a big delay and choppy sound, like a mismatch of ptime.

 

I have already tried to put rtp-autofix-timing=false into the profiles and even changed the inbound-codec…. to g729@40i, but nothing helps.

We have done a test with the provider switching for a test call to 20ms and the sound was perfect.

 

The issue now is that the provider can’t keep this setting only for us, he wants to send with 40ms.

 

Is there a way to configure it on Freeswitch?

 

Thank you

Anestis
