Don't know. I doubt they do though.

These days you can build a nice server well under $500. Colocating them is also cheap if they're in 1U form, and bandwidth is really not that expensive if you shop rates. >From a user to server perspective, you can easily fit 1000 users on a server, and probably more than that. The cost per user is less than 10 cents assuming a colo price less than $100/month. Even higher than that you're still talking a few cents more per user. The only problem I found scaling is the need for some type of load balancing - and I'm taking your advice on that one (thanks!) and looking to put Kamailio in front of an array of media servers. Once that's done and working properly, I really see no reason why we couldn't scale to tens of thousands of users by just adding more media servers as we need them. :) One of the things I am sturggling with is how to get Kamailio to account for geographic location and divert a west coast user to a west media server rather than east, but I guess that shouldn't be too hard to implement eventually. (maybe look at the IP address - or if possible with kam, just store an indicator in the database that will tell it what array of servers to divert to) Anyway.. point being - servers are cheap, colo is cheap, and bandwidth is cheap and always getting cheaper. The cost of proxying media are negligble in the type of business model we run. Again- a wholesale operation may very well find it makes more sense not to proxy the media since they don't have to deal with NAT and other such headaches anyway. -- Nitzan http://www.comparevoipproviderrates.com/ _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
