Re: [Xen-users] AsteriskNOW on Xen Choppiness
Ian Tobin said the following:
Hi,
Just curious, are you using this for IP related calls only, no analogue etc?
If you are using Zaptel hardware for an analogue line (ie a TDM400 or
similar card) you will not get the interrupt performance required for
reasonable call quality. I fought this long and hard a couple years
ago. There is a utility, I forget its name off-hand, that will test the
interrupt performance for the Zaptel hardware. voip-info.org should
have information on it.
If you are in a pure voip situation, where all call traffic is handled
over the network and not with hardware interfaces, you should be able to
use a DomU without much difficulty. The one gotcha is that you will
need to use the dummy Zaptel timing device for conference calling and
music on hold to work properly.
