I have been a Cari.net client for over a year now, but I am needing a more powerful server and I don't want to pay $200+ a month for it. Hetzner has a connection to the Level 3 network that recently installed a transoceanic fiber optic link with a lag of less than 40 ms. You're not going to get much better than 40ms each way from NY to Europe because as Scotty would say: Ye canny break the laws o' physics! (Actually light in fibre takes 26.1ms according to Wolfram alpha but London to NY has been ~40ms each way since as long as I've been involved with that stuff (mid 90's) And most big ISPs in europe now connect to Level3 - e.g. the co-lo I use in deepest darkest england (nowhere near London, although we do have Gb to London) has a ping time like: gordon @ unicorn: ping -q -c10 www.nyiix.net PING ns3.nyiix.net (209.137.140.21) 56(84) bytes of data. --- ns3.nyiix.net ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 9009ms rtt min/avg/max/mdev = 78.865/79.947/86.082/2.079 ms It goes via L3 and that's probably not the best end-point, but it's close enough, and ~40ms each way. The total lag from Germany to USA (2 way) is around ~110ms (Just tested it today). Who this cause any issues with my VoIP applications? Right now I have two VoIP boxes installed in Switzerland which are connected to my server in California (avg response time = 190ms) and I have no problems at all. What would you guys advice? So are you passing data, or just signalling? If data, then why? (Although I guess you're actually terminating to the PSTN in those countries?) But as you already have servers in Switzerland, why can't you use those to run some extended tests, and work it out for yourself? Personally, I'd not even think about servers in another country unless I had good reason to - and good remote hands/support, etc. and a requirement to plumb in to the local PSTN - either directly or via a local VoIP carrier - and even then, if it's via a local VoIP carrier - why not just connect directly to them from 'home' rather than put a box over there. But I if you already have servers in .ch which you indicate you're happy with, then I guess you do have good reason to have them there, so since .de is just up the road from .ch, then if you're happy with the ISP/co-lo then go for it... Do make sure the facility has multiple carrier ISPs though - if L3 does go down (and no-ones perfect), you still need a way to get to it - L3 isn't the only backhaul ISP with trans-atlantic links - get the co-lo's AS number and see who they're peering with using the various 'whois' tools, etc. Good luck!

Re: [asterisk-users] Server response time
Gordon, Thank you very much for the detailed insights! I really appreciate it. I'm gonna test drive a server in Germany today. The main reason for choosing a server in Germany is COST ($65 vs $200).

That must be one hellofa server and bandwidth package! I'd still be wary of sending media over the atlantic and back again though - it's a lot on Internet to rely on, even if the ping times are low enough.

Gordon I was very surprised with the price as well. The best package I could find in the US was with a company called Server Beach (a Peer1 company). And in Germany I found Hetzner.
