Hi, Try without virtualisation first, it may screw your timers. Regards, Alex On Fri, Sep 28, 2018 at 12:44 AM Antonio Modesto <modesto916@gmail.com> wrote:

Hi everyone,

I have had some problems lately with poor call quality when using FXO channels (mod_khomp) talking to sip phones. Using wireshark I noticed that the RTP stream sent from FS to my SIP device had some packets with wrong timestamps. After changing the rtp timer from soft to posix, the problem was solved. Do you guys know if there is any side effect in using the posix timer?

*I am running FS 1.6.20 on a XenServer VM with Debian (Kernel 3.16.0). I can't upgrade to FS 1.8 because Khomp still does not support it.
