BTW... here are my initial thoughts on a GV "route" change for my OBIHAI usage.
http://www.circlenet.us, web site is simple, managment UI, simple, but you know what, if you're making phone calls, how important is the web UI?
Given the implosion of XMPP shuttering the door over at Google Voice, I sought out a hopefully reliable, great audio quality, pay for what-you-really-need provider. GV still has hands-down best spam/telemarketing control.
To that end, I'm using CircleNET for the only service they provide: outbound calls. And GV -> FreelyCall ->ObiHai will be for inbound. latency not a problem with the top-tier routes between broadvoice and FreelyCall even with FreelyCall's Frankfurt, Germany (at least from what I can tell on routes) SIP server.
**I truly believe that by CN focusing on outbound, they do it better than most for less than all that I've seen so far.**
That said, this is "early-on" for the "unbundled" VOIP for me, so I've got a lot to learn and will hopefully learn more, but CN reflects great values, even as simple as finding ways to get low to no cost calls for public servants that are separated from their families by distance and months-years at a time.
Service is non-contract, pre-paid via PayPal, they offer a $2 credit to "try on their 20 dimes". So far the 75 minutes have all been more clear than the Google Voice calls and would have only cost $0.30.
Why pay more for phone service, with a little work, find the best incoming provider(s) GV +FC and so far best outgoing CircleNet.us (FC is
freelycall.com, they offer free WA, USA DIDs w/ free incoming minutes, manual implementation, but friendly/efficient service all things equal)
