Yeah. ViciDial (the call center software my company writes and maintains) using Asterisk as the telephony engine. We use the Web 2.0 Model for clustering which means you have multiple servers with relatively small "footprints" and fail-over set-up on the endpoints. If a server dies the endpoints can fail-over in about 3-5 minutes.

We've also looked into virtualized Asterisk (SIP-only) but ran into issues with getting a stable hardware timing source through the abstraction layers. We started writing our own Zen timer called ZenDummy but determined that is was unmaintainable.

It's always nice to meet new people. Specially when one of them happens to delve into the same stuff I do.

What you went through illustrates why it took us over two years to get it right. But that is only part of the hosted dilemma. Our ability to leverage the physical infrastructure and relationships with the Major Tier1 and 2 providers that we slowly built up over a decade for our virtual systems has put us in a unique position to deliver service with virtually no latency or jitter. And our failover interval is measured in milliseconds, not minutes.
