Disruptive Telephony

Skype Journal had this post today that was short enough to be captured in a graphic:

Indeed. How many other startups have ditched landlines, IP PBXs, etc.? Tools like Skype make that rather trivial to do, especially when voice no longer matters as much in everyday business communication.

Interesting times we live in...

One interesting development in the world of Skype last week which I've seen little mention of is the fact that the folks at Highspeedconferencing.com have rolled out a Skype Extra that lets Skype users have large-scale conference calls. Like most such large conference bridges, they have moderation/"hand-raising", call recording, email invites, etc. However, the key point to me is that their conferencing bridge uses the wideband audio supported by Skype! That is the key. You now have conference calling with audio quality that is far better than the PSTN! This is where we start to get into the space where VoIP can offer a truly different - and better - user experience than traditional telephony. The Skype blog touches on this:

HighSpeed Conferencing is the only audio conferencing service available to Skype users that offers high-definition (HD) voice quality. There’s no degradation of audio quality, no matter how many Skype users participate in a conference call. And with unlimited usage during a conference call, you can talk as much as you want. Some people stay on the conference bridge all day.

I've not yet used the service as right now I'm not involved with large conference calls, but at the point that I do I will very definitely check it out. (On a tangent, I wonder if Polycom has a trademark on "HD Voice"?) Have any of you tried it out?

Whenever I'm using Skype, I have the "Display technical call info" setting enabled so that I see technical stats about the calls I am on. Those windows tend to stay around after a call... and I noticed this one still around with an identity of "securesip". (click on the image for a larger version) I've tried to replicate this with calls that I've recently made to see if I could get the window again, but can't seem to do so. Anyone know why I might be seeing this?

I'm curious...

The big news out today in the world of Skype is that Skype and the mobile carrier called "3" have released the "3 Skypephone" that lets Skype users take Skype truly mobile. Skype-to-Skype calls and IMs are "free" provided that you are on "3"'s mobile network. I say "free" in quotes because of course you have to have a wireless plan through 3. There are actually two options in the UK, which is the only country in which it will initially be available:

• Monthly - With this plan, the 3 Skypephone hardware itself is free and the rates are 12-17 British pounds per month. Apparently you have unlimited data connectivity with this plan, so you can in fact make unlimited numbers of Skype calls or IMs.
• Pay-As-You-Go - With this plan, you pay 50 pounds for the 3Skypephone phone itself and then keep your account filled with credits. Apparently data usage decrements this account (but it's not clear by how much), so you have to wonder how often people will need to recharge the account. (UPDATE: Julian Bond, who is in the UK and has a 3 Skypephone to experiment with, informs me that there is apparently no charge for data usage on the Pay-As-You-Go, but it is only available for "30 days after your last top-up". So as long as you top up each month you would apparently get the data usage for free.)

These plans also factor into your non-Skype calls, i.e. calls to regular PSTN phone numbers. The phone does work just like a regular cell phone, but calls you make do not go out via SkypeOut but rather through 3's mobile network. So if you are: 1) calling other Skype users; and 2) on 3's wireless network; then all your calls are "free" (subject to your calling plan).

All in all an interesting play. We won't see it in North America for some time (and I probably won't see it in Vermont until the next millenia) but it will be available in the UK on Friday and by the end of the year in Australia, Italy, Hong Kong, Sweden, Denmark, Austria and the Republic of Ireland.

The phones themselves look quite nice. There are three colors (or two colors with one of the colors having two different color bands):

Luca Filigheddu also notes that the 3 Skypephone has a "Web 2.0" component to it in that you can easily access various social networking services:

I understand from folks who were at the launch event in the UK this morning that 3 Skypephones were made available to reporters and bloggers this morning, so we can expect to see more articles appearing in the hours ahead. In the meantime, here are some links to other sites that have been covering the launch:

• Skype Journal: "3 Skypephone for 50 pounds on 2 November"
• Skype Journal: "The 3 Skypephone is a test"
• Alan Williamson: "The 3SkypePhone Arrives ... first thoughts
• Blognation UK: "Skypephone unvieled - an interview - includes an audio podcast
• Engadget: "3 Skypephone is free in the UK"
• ZD Net: "Skype and 3 launch mobile phone"
• Tech Crunch UK: "Three to launch Skype phone today"
• CNN Money article

• Skype product page
• Buy 3 Skypephone page
• 3's page on the Skypephone
• 3's "Fast Guide" for the Skypephone
• 3's information about the 3skype.mobi website

Naturally, YouTube videos are starting to appear. Here's a 9-minute overview from an Italian Cellular Magazine (in English):

Stay tuned for more info in the days ahead.

Boy, did I choose the wrong week to go dark! Way too many amazing things going on out there this week... here is a quick view of some of the disruptions with relevant links:

• Microsoft formally announces release of Office Communication Server - tons of coverage out there but I recommend the analysis by the UC Strategies team.
• Skype will be providing voice to MySpace IM - again tons of coverage - Skype Journal has more info and a screenshot. See also the Skype blog.
• Per Business Week this morning, Skype will be rolling out its own mobile phone, starting in Europe.
• MySpace
• Apple, meanwhile, announces an upcoming developer kit for the iPhone via a note from Steve Jobs (some reactions here and here).
• And finally MySpace says it will open up to application developers in a similar manner to Facebook.

All in all a rather busy week! (And it's not over yet...)

Not necessarily a great day over at Skype today - per the eBay news release, Niklas Zennstrom stepped down as CEO, eBay paid $533 million to "settle obligations to certain Skype shareholders" and is also taking a $900 million charge to write down the value of Skype. From a Bloomberg article:

``It has not performed as well as we would have hoped in the short term,'' EBay spokesman Hani Durzy said in an interview. Skype was profitable the first half of the year, he said.

Many others out there have already offered their analysis and so I'll point you to them today:

To my immense surprise, my article yesterday about my challenges with Skype and my hotel Internet connection just hit TechMeme today, so welcome, anyone who is coming my way from there. But that also prompted me to want to offer up some additional thoughts on the subject.

First, I'm actually quite annoyed at the Best Western here in Ontario, CA, for essentially blocking Skype by virtue of their network security traffic policies. If travel shall bring me to Ontario, CA, again, you can be pretty sure that I will not be staying here. Skype has become an important communication tool for me and <cue violins>was the way I was intending to call home and stay in touch with my family</violins>. Skype has worked great at the hotel I was at earlier in the week in Phoenix and in fact at every other hotel I've been at lately. I do intend to contact Best Western to express my dissatisfaction at being unable to use the program.

Having said that, as a security professional I do understand WHY the security team at the Internet provider to this Best Western hotel has the policies in place that they do. As Phil Wolff commented, Skype's launch "can look like the beginning of port scanning or a bot-gone-wild". Given that this provider is dealing with hotel rooms where random strangers are connecting who-knows-what onto the network, they have to be extremely vigilant (especially because customers like me while complain quickly if Internet access is slow/unavailable). The more I think about it, hotel networks are really an absolute nightmare from a security point-of-view. You have no way to enforce virus protection, people can put all sorts of machines in all sorts of states onto the network, systems with spyware can easily be scanning/attacking your network -it's really pretty crazy and I'm glad that I'm not involved with running such a network! (Although the security geek in me would admit that the aggregate data they must get from network traffic would probably be fascinating.) However, there is probably a compromise out there where the ISP can tune its filtering rules so that if it sees such traffic and can identify it as Skype traffic, it can not trigger the MAC lock-out.

Which brings me to the final point that there's a lesson here for anyone developing P2P apps, or I suppose any other apps that have a similar traffic profile. If the apps generates traffic that looks like a bot or port scan, odds are that it will be blocked in some places like this one (and the hotel Phil was at). It would be great if developers could take that into account and either: a) naturally put in some kind of rate throttling; or b) perhaps provide a "hotel mode" where it throttles back the number of sessions to some (perhaps user-settable but with a default) value. This of course would make it longer for things like presence information to appear, but would at least let you continue to operate the program without triggering the network security alarms. Of course, you'd have to change to that mode, which many people would forget to do and wind up being locked out, but it might be an interesting "advanced" option for those who know what to do with it.

Any other "lessons learned" you see here?

UPDATE: I have now posted some additional thoughts about this issue.

---

It's been a frustrating time here at the hotel in Ontario, CA, where all I've been trying to do is use the Internet connection. I'm staying at the Best Western and did so largely because they advertised free high-speed Internet (they were also cheaper than others). First annoyance was discovering that I was too far away from their APs to use wireless, but since I had an ethernet cable I just plugged into the wall jack and expected to get access. The very first time I connected, I did get an IP address and could see an entry in my routing table for the default gateway. However, I couldn't ping it.

Being rather used to network troubleshooting, I did the usual things... bringing the interface up and down, disconnecting and re-connecting the cable. I even went to the hotel lobby and got a new cable in case the issue was with my portable/retractable cable.

Nothing. No net.

In desperation I did the thing that tech support always tells you to do but I avoid... reboot. Nothing.

So finally this morning I got on the phone to the Best Western tech support and after waiting, oh, 20 minutes or so I got through to a tech and ultimately we figured out the problem:

Skype!

More specifically, all the bizillion connections that Skype was making out into the P2P cloud. The tech reset the switch and asked me to connect again and his immediate response was "Whoa! Something on your computer is generating an incredible number of sessions out to the Internet! You are tripping our filters and it is blocking out your MAC address." With him on the phone, we tried some experimentation. I shut down Skype, at which point he said I was generating much more normal traffic. As soon as I launched it again, he noticed a very large jump in the number of session connections I was establishing. He said it was something like 396 sessions he was seeing coming from my computer. He also said that I'll keep being locked out of their system if I keep Skype running.

So I shut down Skype. Which, of course, is annoying. Part of why I wanted to use the high-speed Internet is to use Skype for IM and for voice/video calls.

I find it a bit odd that Skype was generating so much extra traffic, but then again I am pretty much always connected into several persistent group chats and had maybe 8 or 10 individual chat windows still open that I'd left open from when I'd last been chatting with the person. (The Mac Skype client makes this easy to do, but I'll write about that sometime.) The persistent group chats, especially, do generate a good number of connections as they link out into the P2P cloud. Perhaps if I closed all of those windows and killed off all my individual chat windows Skype might have behaved better. (Or perhaps not, I might have had to leave the persistent chats in order for Skype to stop making those connections.) I don't want to try it out, because I do want to keep my Internet connection up right now.

In any event, should you be at a hotel and find yourself unable to connect... it might be a P2P app like Skype tripping off the hotel's filters and blocking your access. Fun, fun, fun....

The first result of the Skype Mashup contest was announced yesterday at the Skype developer event in Prague, and the winner is....

PamFax!

Yes... a fax application!  As Jim Courtney writes over on Skype Journal (he was also one of the judges):

The PamConsult team created PamFax to solve the problem of providing a very simple process (especially relative to the somewhat cumbersome WinFax) of using the Internet to easily fax an MS Office document anywhere worldwide. The primary Skype feature here has nothing to do with voice; they used the Skype Extras publishing platform not only to install the application but also as a transaction processor for collecting revenues for the service using Skype credits. Skype Chat is used to send notifications re a fax's delivery. In addition they developed a web-based portal to manage and archive your use of the service. The application can be launched from the Skype Extras menu or from within MS Excel or MS Word. A link to Google Maps will also show roughly where the fax is being sent (to within an Area Code).

The interesting aspect to me is how it uses Skype's micro-payment infrastructure.  No need for credit cards or anything... it just debits your Skype Credit.  Your Skype Credit, in turn, can be linked to your PayPal account... which can then pull money from credit cards or bank accounts.  So you wind up with a very effective and simple way to bill people for services rendered.

Jim goes on to explain a bit more about what PamConsult did:

PamConsult married the Google Maps API's, Microsoft Office COM objects and a backend fax API with their long term experience using the Skype API's. They started a year ago this summer with development of specifications; coding commenced in January with an initial version available in May. After a beta testing program in July, PamFax was released as a Skype Extra in the second week of August.

As noted in the Skype Developer blog post, winners in the US and Japan will be announced at those specific events over the next couple of weeks.  

The list of submitted mashups can be found in the Skype Extras gallery.  Some look quite intriguing and I'll perhaps write more about them in the future.

For a couple of months now, a post has been swirling around in my brain that I was tentatively titling "The Dawn of the Mashup Culture" in which I wanted to talk about "mashups" and why they are so incredibly important.  Unfortunately I just haven't had the time to put all those thoughts into the written word.

Well, in the meantime, Jim Courtney went off and wrote something very close to what I was intending to do:  "The Dawn of the Mashup World - Part 1: Challenges, Why and Expectations"  followed by "Part 1a: What is a Mashup?"

Read them.  (And the follow-on posts that Jim indicates he's writing.)

Mashups are fundamentally changing the way we can use and control services.  It's the remix culture. 

You need to understand it... because if you don't, your products and services will be left behind.

Open APIs win.  Mashups win.
