[asterisk-users] LAN IAX2 trunk bad audio quality vs. LAN SIP trunk good audio quality

[Zoa]

I think that the clock resets would cause no audio or garbled audio 
every 20 minutes, not constant interference.
Could you tell us how many simultaneous calls were in the trunk and what 
the size is of 1 voice packet ?
Can you try putting maximum 30 calls per trunk (use multiple trunks if 
needed) and see if the problem goes away.

Greetings,

I don't know how hardware timers work and if Digium hardware rely on the motherboard (my system clock is going too fast and my ntpd is constantly adjusting the clock by -2.6 seconds every 20 minutes). In any case, since I'm on a dedicated LAN I guess I can safely set trunk=no.
