Internet Phones Replacing POTS In Japan
prostoalex writes: "CNN reports on growth of Internet phone services in Japan. The high cost of telephone calls, which many saw as an impediment to spread of the Internet is right now actually a menace to plain old phone companies, as more and more people are switching to VoIP services."
They provide a Cisco ATA186. The only downsides are:
The advantage over cell phone is that there are no minutes! It is $39.95 a month and you can choose which area code you want a phone number in. You can forward it to a cell phone when out, or any other phone that you may be at.
Fight Spammers!
Furthermore isn't Voip ultimately more expensive if you actually had to pay for it? I mean the reason internet service is so cheap right now is that I dont gobble bandwith 100% of the time. If everyone fully utilized their dsl connections theoretical I think we would all be paying more and getting crappier service.
I've recently signed up to vonage digital voice and the techincal service is fantastic.
With some wrangling i've since taken the ata-186 router back to scotland with me. I work for a company in the USA and this gives me a californian phone number and (once i upgrade to the $40 service) unlimited minutes across the usa.
Latency doesn't seem to be a problem although i'm definitely with one of the better uk broadband providers. I'll also soon experiment with setting up QoS on my network to ensure that my 1024/256 doesn't saturate to the point that my voip packets drop.
The main downsides to vonage are:
- They dont let you have the password to the Cisco router which YOU have bought from them - meaning you cant use the second line or easily connect it to a h232 gatekeeper to do intelligent things with.
- They wont bill any credit card which doesn't have a US billing address and wont ship outside of the US (and guyana for some reason)
hmm.... anyone want to join a class action law suit against pacbell / sbc with me?
Don't get me wrong, it still sucks, you just couldn't sue them for it.
There comes a time in every man's life when he must say, "No mother! I do not want any more Jell-O!"
I worked for a company that wrote software for a Japaense company's VoIP phones. Those things had some cool features - you could download pictures off the net and use them as icons on the phone's display, and you could download mp3s and use them as the ringer - a different one for various callers, as well as different "lines".
it was neat to see since really nobody uses them here in the states - but apparently it is really big over there.
There are some odd things afoot now, in the Villa Straylight.
The largest contibution to latency is the encoding and decoding codecs -- that is, the translation from an audible analog signal to a digital signal and back again. The more compression that is desired, the longer this takes. The actual transmission over a network -- using UDP or anything else -- is negligable and has little to do with the packets being UDP or old-world "TDM" voice.
Of course, those UDP packets (the VoIP traffic) can be prioritized over non-VoIP traffic, if the routers support such prioritization and there is a way to mark high-priority packets. DIFFSERV is one such mechanism to do this.
