I have a freepbx with 5 trunks and 40 extension, everything in my network is very fast and I can ping the voip provider around 15ms. I receive random delay when calling or receiving even through the internal network. I read that asterisk virtualized is not a good idea and this is true cause on a test phisical host the problem doesn't happens. I'm using g729 and g722 as codecs. Is there some tweeks to improve the voip performance? I read about Multiqueue in the virtio interface but I don't know how to implement this.
many thanks
