The problem we ended up having with virtualised asterisk (on esx, xenserver and hyperv) was that the clock timings to the vm aren't always accurate when you're using dahdi_dummy.
We had a bunch of voice quaity issues which took ages to diagnose because of this. Obviously if you have a DAHDI card that your passing through to the vm or one of these http://wiki.sangoma.com/sangoma-wanpipe-voicetime you can avoid this. -Blake On 11/06/12 5:07 AM, "Chris Bagnall" <[email protected]> wrote: >On 8/6/12 9:17 pm, Hiers, Richard wrote: >> I don't expect to need to use any special hardware, just a sip trunk >>over our broadband connection.
