Hello Guys,

We're running kvm with installed freepbx (asterisk).
For Initialzing a call we get SIP(UDP) Invite Packages to Port 5060 but our system needs often more than 3 seconds to react.
Our Sip-Trunking-Provider will then give a busy line back to the caller..

most of the time the kvm with freepbx idles.

what we found out...:
if we make a permanent ping from our kvm (freepbx) to a public ip-adress the described issue is gone away.
But this can not be the solution ;)

kvm is a freepbx based on cent os
kvm guest has a intel networkcard, briged

any hint would be very nice.
thanks a lot
