The dirty secret of IP calling, and how it will change the phone industry

IP calling for me is a major disappointment at the moment - I've been on far too many conference calls where people are on all manner of different VOIP ways to connect to a call - Skype, Cisco etc etc - it's low quality, tonnes of echo, missed words.<p>What's even worse is when you have people from another company with a different VOIP provider / technology - then it becomes a joke.

I'm currently using T-Mobile with an unlocked Galaxy Nexus (GSM version). The only feature that I currently use from T-Mobile is their data connection. For voice calls I'm using Google voice and Skype:<p>(1) With most of my friends I just use Skype for calls, as I have it running on my phone all the time.<p>(2) As fallback, my Google voice number has Jingle (Google Talk) forwarding enabled and on my phone there's a client that is able to accept Jingle calls. So I'm also reachable on a traditional phone number.<p>Disadvantage: Unfortunately both applications considerably decrease battery life.<p>Advantage: Skype voice quality is much better than regular phone calls. I don't need to use one specific endpoint device (my mobile phone), but can also use my laptop to receive calls. I can travel without having to give my new phone number to all my friends.

UMA seems to overcomplicate matters greatly. How about just giving me a SIP endpoint that corresponds to my mobile number, and, when there's an incoming call, query my SIP presence, if I'm present, ring the SIP, if not, ring mobile. SIP also supports SMS if I'm not mistaken.<p>Baking this into a carrier-branded Android/iPhone/Symbian/WP app should be fairly simple, as the SIP implementation already exists for all of these.

I used to be a happy t-mobile customer thanks to UMA...cell coverage couldn't make it to my house, since it was only 1 bar in my front yard and I live in a block house with a metal roof, but thanks to UMA it didn't matter. Eventually I got tired of having a crappy blackberry phone, which was all they had that supported UMA at the time, so I switched to Verizon which actually does get reception in my house, just barely.

I'm in the Republic Wireless beta, and it's working great so far. There were some echo problems at the beginning, but they seem to have mostly fixed that.<p>$19 a month for unlimited everything, and it actually works everywhere in my house, unlike AT&#38;T and T-mobile.

I think the bigger trend here is "internet protocols will win." We see it happening in telephony, television, music, and lots of other places.<p>Brilliant engineering has gone into the IP stack, with modular support for every aspect of getting information from point A to point B. Packetizing information, routing around network problems, dealing with congestion, choosing whether to prioritize getting every packet correctly vs getting packets in real time, discovering other network nodes, authenticating and authorizing, etc. The internet has all these problems solved pretty nicely, and the stack is flexible enough to do everything from voice calls to email to video streaming.<p>Yes, we still need infrastructure. Companies who provide cables and towers and satellites and fiber optic links are absolutely necessary. But flowing over those links, everything is moving towards IP.<p>It's silly that we still ship CDs and DVDs of audio and video data in boxes. It's silly to have a thousand TV channels streaming one-way to your house with no ability for the viewer to choose what they watch and when. It's silly, as this article points out, not to always choose the best pipe for my purpose.<p>The big trend is that infrastructure and services are being decoupled. "Dumb pipes" is an insulting way to say this: running a data network is still hard. But yes, the pipes should be neutral. We should pay for the best connection and, separately, use the best services we can reach over those connections.<p>As we keep finding ways to use the pipes for our purposes, we will keep converting all communication to the IP stack. Because it's better. It just is.<p>Dumb pipes + smart protocols will win. It's just a matter of time.

I have a T-Mobile phone (HTC Sensation) and I love wifi calling. It works beautifully where my cell coverage is bad and there's a good internet connection (home, work, a ski lodge I was at recently).<p>I'm on T-Mobile more or less accidentally, and before I got my smartphone, had absolutely no loyalty to them. I didn't even realize the phone had the feature until I got home and started playing with it -- they didn't play it up at all in the store. It would be hard to pull me away from T-Mobile. A competitor would have to offer a huge price break, or wifi calling.<p>Really puzzling that they don't make a bigger deal of this feature.

And now how about a "dirty secret" for Kineto Wireless mentioned in the article several times. When their code is running on an Android device, even when wifi calling is disabled, it spews an endless stream of messages to Android's log (aka logcat). Often several messages every two seconds. Almost all at Error level even though it just appears to be signal strength information. This is ridiculously amateurish. It is highly annoying as a developer to have to keep filtering this crap out. It also implies they don't bother to check what is happening with their own code.<p>I have emailed their support who didn't respond. I even wrote a Google Plus post about it:<p><pre><code> https://plus.google.com/110166527124367568225/posts/h4jK38n4XYR </code></pre> I often find their code gets wedged too. It gets into a state where it isn't working, but you can't enable or disable it. The only recourse is to reboot your phone.

I love the seamless WiFi calling on my Galaxy S2 (running MIUI ROM). When I'm at home or work and have free WiFi, I can make calls for landline prices (and cheaper if the call goes abroad) without launching an additional app etc. When I'm out of WiFi reach, the phone automatically chooses the mobile provider.

Encryption. That's what I'm looking forward to with native SIP support on all mobile devices.

Am I the only person who just wants a ip telephone capability for my already Skype capable smart phone? I mean the telcos are dumb pipes so why do we still separately pay for sms separately from the data?

I find it sickening and pathetic that things like "tethering" and "making skype/voip calls" are somehow special features that most providers are trying to keep you away from in every way they can... I have this awesome little device that could do almost all the things I typically do with my PC and I can't do half of them just because a few big-enough corporations decided those features are TOO frakking awesome and they would endanger their holy cash cows.<p>There is something about lobotomized technology for nothing but greed and political reasons that REALLY rubs me the wrong way...
