Sure, Heres a basic overview:
- All IP (no local E1/T1 connections). - 2Mb Fiber internet pipe backed up by a DSL backup. - Single Asterisk server (with a backup clone on standby). Config currently backed up to SVN and copied off by tarball by webmin to a separate network. - Both IAX and SIP connectivity to 2 providers, with A*k Dial command driven failover for outbound calls (PSTN inbound limited to one provider). - All UPS backed. That's about the current config. This is an office/company config, not a reseller. Main points of failure: Fiber/DSL Box (easy to swap out). Same for the Fiber/DSL lines themselves. The main A*k box itself. I've covered all the redundancy I can (within budget) of the connectivity, and I'm wondering what I can do with A*k itself. I'm guessing that SIP proxies might be overkill (as I'd then need redundancy within those too), so maybe it's a case of looking at Linux-HA.

It's been my experience that this usually works fairly well for stateless protocols like HTTP, but doesn't do so well on stateful protocols like SIP and IAX, and in general is a much more difficult problem to solve. Most people tend to use some combination of SIP proxies (such as SER and OpenSER), DUNDi, shared storage, redundant databases with replication, T1/E1 failover boxes, and horizontal scaling to make Asterisk more highly-available. Of course, I haven't really gone into much detail here, but hopefully it helps answer your question. (It's also my personal experience that people who know how to build such solutions are making enough money off of selling their solution that they aren't real eager to give away all their secrets.) In reality though, you say the word "cluster" and it means five different things to five different people. To really be able to answer the original poster's question, we'd really have to know a lot more about his architecture and his potential points of failure. -- Jared Smith Community Relations Manager Digium, Inc. _______________________________________________ Sign up now for AstriCon 2007!
