If you have your PBX hosted at some distance from your office and phones, how much does that affect the call quality? Seems those providing hosting are based in Auckland whereas I'm in Wgton. And what about setting up a cloud based pbx on EC2?

gchiu: If you have your PBX hosted at some distance from your office and phones, how much does that affect the call quality? Seems those providing hosting are based in Auckland whereas I'm in Wgton. And what about setting up a cloud based pbx on EC2?
gchiu: I was thinking of using rentpbx.com for a home pbx system .. save me the power on running my own box. I would continue to use Open VFX as the SIP provider.
sbiddle: Unless you configure re-INVITE correctly a US provider would be terrible. 150ms for your call to the US and then another 150ms back to WxC
gchiu: Actually it wasn't so terrible. I signed up to rentpbx.com for a PIAF purple and configured an extension. Then called my home phone which is a POTS line. Voice quality was acceptable to me. I called another number and they said I sounded distant.
Maybe I have a 150 msec ping to them but I wonder if WXC have a much lower ping time to them?
The cost is $US14.99 a month, and I can cancel in 7 days for full refund which I will probably do. But I get a 1.2ghz processor, with 200Gb of traffic for this.

gchiu: I just realised I was using 2talk. But here are both.

hmm you have the same problem of routing through australia. as well as that, it appears to be giving high pings to san jose.. like from two different los angeles hosts there is around 8.4 msec ping to hop 4...

mercutio:
anyway, it's kind of moot.. routing to the US and back again for NZ phone calls is silly! even for initiation it's not a wonderful thing. what if there's a war? what if there's a cable cut? what if US decides to monitor all phone calls?

I guess they'll find out what I am having for dinner that night!
I might hook up a googlevoice account to this and see how it works for talking to US based relatives.
