Disruptive Telephony

Somewhat predictably, the blogosphere is going nuts about the Skype outage.   It's currently at the top of Techmeme.  As Tris Hussey notes in his post, Skype has indeed become a key communication tool for many individuals and businesses.  Other VoIP bloggers offering commentary:

• Om Malik: "Does Skype Outage Expose P2P's Limitations?"
• Tom Keating: "Skype Outage" - wonders if it had to do with the Microsoft updates (I would think not because the outage happened to me prior to me installing the updates)
• Andy Abramson: "Skype Suffers Major Outage" - helpfully points people to Gizmo and SightSpeed as alternatives

The Register, of course, chimed in with their normal attitude.  Ars Technica, meanwhile, commented that the outage was surprising mostly because of ""how often it doesn't happen".  Taking another view, Mashable is reporting that eBay's stock has dipped this morning.

Meanwhile, Skype users around the world consider what other IM programs to use and some of them will, maybe, just maybe, have to actually pick up a phone today!

As a Skype user, I was a bit surprised when, after restarting my computer today (due to a crash when I was trying SecondLife with voice, but that's another story), the Skype icon just kept on spinning and spinning saying "Connecting".  And then it would be online... and then it wasn't... and then it was... and then it wasn't....

My first sign that it was something larger than my (sometimes flaky) laptop was a Facebook status update by Jim Courtney saying that Skype might have an outage for 12-24 hours.  About the same time I saw a tweet from Chris Brogan.  The "social networking information sharing network" was hard at work...

A trip to Skype's "Heartbeat" page showed the problem:

Oops.

Nicely, though, Skype staff have posted a status update on their heartbeat page:

UPDATED 14:02 GMT: Some of you may be having problems logging into Skype. Our engineering team has determined that it’s a software issue. We expect this to be resolved within 12 to 24 hours. Meanwhile, you can simply leave your Skype client running and as soon as the issue is resolved, you will be logged in. We apologize for the inconvenience.

So sometime within the next while it will be back up.  It will be curious to see if anyone at Skype will provide technical explanations of what happened.  I note from another status update that they performed some planned maintenance last night.  Perhaps something did not work quite right?

In any event, I would think Skype will need to offer some post-resolution reassurance to all those businesses they are so eagerly courting...

 Since I have written here about the new Skype clients for the Blackberry, such as iSkoot and IM+, and questioned the security of those clients, I feel compelled to note that Jim Courtney over at Skype Journal, who also writes a good bit about Blackberries as well as Skype, has posted his response to the issue on Friday:  "Security, Skype and the Blackberry".

I still suffer a lingering uncertainty, but I'll admit that Jim's digging does seem rather persuasive.

Why does my voice change in audio quality about half-way through the new Telecom Junkies podcast?  Here's the story.

A few minutes ago I posted to both the Voice of VoIPSA weblog and also the Blue Box podcast site a note about the new Telecom Junkies podcast that features an interview with Robert Moore, one of the two people involved with the large VoIP fraud cast last year.  About mid-way through my connection dies and you hear Jason saying "Oh, we lost Dan!" and then I'm back, but with a much softer voice.

Since it says something about telephony - and since I'm also interested in relaying lessons for podcasting - here's what happened.

In the hotel I was staying at in Florida, I was getting pretty poor connections using my AT&T GSM phone (the replacement Blackberry had not yet arrived).  I'd noticed that when calling people from my room, even if I went out onto the balcony, calls would still drop out sometimes - even when I was sitting still.  Now I don't know if this was because I was on the 20th floor (room 2048, what a great geek number!) or because I was at just a particular angle for the GSM towers or what.  The phone seemed to indicate that I had great connection strength.  All I knew was that connections were dropping. 

Needless to say, I was a bit concerned going into the Telecom Junkies podcast recording.  Jason Huffman records his shows by having everyone call into a hosted conference service.  When the recording is done, he gets an email with a WAV file, slaps on the musical intro/outro, potentially does some minimal editing and posts the show to their website.  As Blue Box listeners know, I'm always looking to get the best audio quality possible so I was a bit concerned.

Given that cell phone coverage was problematic, I decided to try using a softphone over the hotel Internet.  Unfortunately, I am on a trial system for Mitel's softphone (using the latest development versions) and I had received the notice that I need to upgrade to a new trial load to keep using it - and hadn't yet downloaded the new version.  So I thought I'd use Skype instead.  However, I also had the dilemma (for either softphone) that because of space considerations I had left my nice new USB headset at home.  Given that I've had reasonable success with Skype's new 3.5 and no headset, I figured I would give it a try anyway.

So I actually first called into the conf bridge using Skype/SkypeOut and spoke with Jason briefly to ask about the sound quality.  He said I sounded a bit quiet and rough (keep in mind that I'm talking to the mic on my Dell laptop), so I called back in on my cell phone.  However, I didn't disconnect the Skype connection, but instead muted the microphone and plugged in a set of headphones so I didn't hear it.

Mid-way through the call, my cell-phone connection did die.  What I did next was put the PC headphones on and un-mute the Skype microphone... ta da... I was back in the conf call, albeit at a lower volume level.  So when you listen to the recording, the first part is via cell phone (and includes an audio cut-out or two) and the second part is via Skype without a headset microphone.

I thought there were a couple of interesting points here:

1. I have got to find a really small headset that I can carry with me when traveling.
2. VoIP can beat cell phones in availability (not that any of us in North America will even remotely dispute this!)
3. It's good to have backups when doing interviews remotely.
4. It never even occurred to me to use the hotel landline!

Let's think about that last point for a minute.  I had, sitting right there on my desk next to my computer, a perfectly functional phone tied into the hotel's PBX.  And yet, it never even remotely occurred to me to use it!  In fact, outside of calling within a hotel I can't think of the last time that I've actually ever used a hotel phone for an external call.  It's been probably... years!  I guess I've gotten too used to the typically-extortionist rates charged by hotels for phone usage that I just don't even consider it.  (Well, and every other time my cell phone has worked well!)

In any event... that's the story behind the story...  :-)

About a month ago, I wrote about the "IM+ for Skype" client that let you use Skype on your Blackberry. Well, a new version 2.5 is out now and Jim Courtney over at Skype Journal has a review.  Jim is quite enthusiastic about a new feature that lets you specify the number at which IM+ will call you back (rather than only calling you back on your mobile).  I also found this interesting:

As an added benefit, IM+ 2.5 will not only make calls to those in my Skype Contacts but also my Blackberry address book. In summary IM+ provides a very versatile way of combining access to both Skype and Blackberry resources.

Interesting to see the merger of Skype and Blackberry directories.  I've not yet played with it and don't see myself having the time to do so in the next bit, but Jim says he'll be writing more in the time ahead about it.

Last week I wrote some first impressions of iSkoot, a new Skype client for Blackberry, and while I still think it's a very cool idea, I don't see myself using it all that much.  Why not?  Very simply...

Battery life!

Or the lack thereof.  Yes, indeed, it all does seem to come down to batteries, and iSkoot seems to certainly consume its share of power.  Now granted, my Blackberry 7290 is an older model and for all I know could probably use a new battery, but in "normal" operation, I can charge it up and then have it run for a good 3 or 4 days before it needs a recharge.  However, start up iSkoot and I found I suddenly needed a recharge by the end of the day!

In fairness, iSkoot is not alone in this... the other Blackberry IM clients I've used, both the Windows Messenger client and also most recently the IM+ client for Skype also have this same problem.  I'm assuming it has something to do with the need to regularly use the data connection for updates to status and to update chat messages.

I can see this actually being most useful to me when I'm traveling and need to quickly reach someone from within an airport or something like that. Of course, that's also when I want the longest battery life, too!  I think I'll keep it installed on my BB, but I don't think I'll have it running except for those times when I'm somewhere and I want a quick way to do IM via Skype.

Too bad, really, because one of the fun aspects of it was that I had a very easy way to read Twitter updates and Facebook updates on my BB (since I have both Twitter and Facebook status streams piped into a Skype chat).

Ah, the joy of batteries...

NOTE: Please see the updates at the bottom of this post.

Back on Monday, Jim Courtney over at Skype Journal IM'd me (on Skype naturally) asking if he could do a test call to me on "another Skype client for the Blackberry". Naturally, I said yes and in a moment or so we were speaking.  It turned out that he was using a new beta application from iSkoot.  From the news release:

The new iSkoot v1.1 delivers a comprehensive mobile Skype experience on BlackBerry: With the click of a button, users can instantly chat with their Skype contacts, make and receive Skype calls, and use SkypeOut™ to inexpensively call regular phone numbers nearly anywhere in the world. iSkoot v1.1 also displays complete Skype contact status information, so BlackBerry users can see which friends, family members and business colleagues are available, as well as manage their own online presence. This latest release features a next generation, easy-to-use interface especially designed for BlackBerry users and will offer additional features soon. iSkoot works without any need for PCs, special hardware, custom phones or Wi-Fi hot spots, and utilizes the existing mobile network infrastructure to route Skype calls through the voice channel.

It sounded interesting and so, of course, I had to try it out as well and finally had a spare moment to do so today.  Now, both Jim and I had commented a month ago about the IM+ Skype client from ShapeServices (my posts first here and then here with a link to Jim's coverage) so that previous experience somewhat colors my own view of the iSkoot application.

The installation was fairly straightforward. I filled out a form on iSkoot's site and was then SMS'd instructions for the download.  I simply opened the link in my Blackberry's browser and proceeded with the install in the normal "over the air" process.  One minor detail was that my Blackberry 7290 was not in the list of supported handsets, but I took a guess that the 7100 binary might work and so I used that (and it seems to work).

Here are some initial positive impressions:

• Nice user interface - Very nice interface.  Tabs that you can use Alt+wheel to move between for your contacts, online contacts, SkypeOut contacts and chats.
  
• Presence worked - I could see the presence of the other Skype users on my contact list.  I didn't try to see what happens when a user changes to see what kind of time delay there may or may not be.
  
• Outbound calls worked, although with an annoying step in the process - Move to a Skype contact and push your thumbwheel twice to call.  (Or push it once to see your options.) The call then starts by initiating a regular mobile call from your Blackberry to a phone number in Massachusetts (for me).  It then seems to call the other person on Skype and connect you through the gateway at iSkoot.  The annoying step was that when I first initiate a call, my Blackberry throws up a menu saying that an application is requesting to make a call and do I want to allow it, with the default being No. I therefore have to scroll up and press my thumbwheel again.  It's a pain and I couldn't find a way to remove that request.  I don't remember having to do that step in the IM+ client (and my trial has expired).  In any event, once the calls were connected, the audio quality sounded fine on both ends.
  
• Chats worked, and alerted you to new chats - Easy to initiate chats. Nice list of current chats.  If a new chat is opened up with you, you get a notification and can open it up.  If there are new messages in existing chats, you get notified of those as well.
  
• No conference call appearance - Unlike the IM+ client, your call just appears as a regular Skype call.  In fact, there was really no way for me to know Jim was not calling me from his regular Skype client.  With the IM+ client, you wound up getting put into a conf call with the other recipient which just seemed a bit strange.

Realizing it is still in beta (like, it seems, most everything on the net these days), here are some negative impressions:

• No support for groupchats - Using the Skype 3.2/3.5beta clients, I'm accustomed to having several public groupchat windows open.  Unfortunately, groupchats are not supported per the FAQ, and my public groupchats did not appear.  This does work in the IM+ client, so score 1 for IM+.
  
• Very slow updates to chats - In our experiment today, Jim Courtney and I both had Skype running on our PCs and so we could see our chat messages in a chat window there as well.  There were times when it took 5-10 minutes for messages typed in the PC chat window to appear in the iSkoot window!  Given that this is supposedly instant messaging, such a delay was hard to fathom.  Now there is a "Refresh Now" choice in the menu which could force a refresh, but the normal process seemed to have some kind of refresh interval.  Not all the time.  Sometimes messages appeared right away... but other times there was as much as a 10-minute delay before seeing the other message.  Hopefully this is just a scaling issue as iSkoot deals with their release!
  
• Slow call initiation process - Forgetting about my annoying Blackberry question I had to answer, the whole process of initiating the call seemed to take longer than the IM+ client did.  I'd have to purchase IM+ to actually test the timing, but the iSkoot process just seemed slower.
  
• Status did not have DND/Busy - Curiously, you can change your status in the iSkoot client, but you only have the choices of: Online, Away, Not Available and Invisible.  One of the ones I use often is "Do Not Disturb", so that I'm not disturbed.  That choice isn't here.  Perhaps the assumption is that you'll just exit the application.
  
• You can't receive Skype calls if you have Skype Voicemail enabled - Per the FAQ.  Not entirely sure why but this seems to be a bit of a headache if you this is not your only Skype client.  I also have Skype on my PC and if I am not there, I'd prefer to have the call go to voicemail.  Since I'm mostly looking to use this for Skype chats and Skype outbound calls, I don't expect it to be a big deal for me (I'll leave voicemail on) but I could see it being a pain if I did want to receive calls.
  
• You still have to give over your Skype password - As with IM+, you have to provide iSkoot with your Skype username and password and then they log in as you from their server/gateway.  As a commenter pointed out, there is a basic problem here that with your Skype account being connected to your PayPal account which in turn is connected to your bank account, you are potentially letting someone you don't know have access ultimately to your bank account.  Do you trust iSkoot (or anyone else) enough?  On the other hand, I'm not sure how any of these services can really work if you do not provide that information.  (See update below.)

All in all, it's an interesting entry into the idea of taking Skype onto a mobile phone.  As I have time I'll keep experimenting with it over the next few weeks... I could see it be especially useful if you were travelling (which, for better or worse, I'm not doing).

As I'll write up in another post, the one interesting use for me was that I could see Twitter and Facebook updates appearing in a Skype chat window and could post Twitter updates (without using the SMS interface)... which was an interesting experience.

In the meantime, if you are a Blackberry and Skype user and want to experiment, you can head over to iSkoot.com and try it out.

UPDATE #1 - 11 Jul 07: Jim Courtney IM'd me with the following comment on the Skype<->PayPal linkage:

btw, I investigated re the PayPal access issue. To do anything meaningful you need to log into PayPal as well. Also PayPal would not allow a process that was open to abuse. All you can buy automatically are voice mail, SkypeIn, SkypeOut and even there you can put on a daily limit as low as $50. And my PayPal password is definitely not my Skype pwd.

UPDATE #2 - 3 Aug 07: Jacqueline Van Meter with iSkoot Product Management has responded in a comment to my later post about iSkoot, addressing a number of the concerns I raised here. 

As announced yesterday on the Share Skype blog and in more detail on the Skype Garage blog (and also in the Windows Release Notes), Skype has released an updated 3.5 beta for Windows.  Skype 3.5 beta came out earlier this month, but this new update includes several new features, most notably the ability to add video into a chat or mood message, and per the release notes it also fixes a range of bugs.  Jim Courtney has more info over at Skype Journal, but I found this piece of interest with regard to the new video snapshot capability (which now allows you to take a snapshot of the remote video, i.e. the person you are speaking with):

Providing your video also implies that your provide your remote participant with permission to make snapshots. Video snapshots inherits existing privacy mechanisms associated with turning on your video.

So basically if you use Skype video, you should be aware that the person with whom you are chatting could easily capture images of you. (Obviously this has always been possible with screen capture programs, but this is now built into Skype.)

On the "adding videos to chat or mood message" feature, my initial reaction was that this could be quite cool... but that enthusiasm was a bit tempered when I realized that you can only add video from specific Skype partners (and currently only one, Metacafe).  Alas, you can not just point to a YouTube video... you are restricted to those at Metacafe.  Of course, you can upload your own video there, but you have to go through the whole account creation process, etc.  It strikes me as a bit odd that given the eBay/Google agreement to work together there isn't yet a relationship with YouTube.  We'll see... in the meantime I can imagine Metacafe will see a spike in new accounts from people who want to experiment with Skype 3.5.

Although I could not earlier find many Facebook apps that I considered true "VoIP apps" that linked out to the PSTN or larger VoIP world, we are seeing more apps emerging.  Two notable new entrants:

1. VoIP User Presence by Dean Elwood

Dean's a friend who runs VoIPUser.org (and provides the SIP voicemail box for Blue Box comments) and he's been experimenting with the Facebook API.  This is the first of what he says will be a series of Facebook apps.  Dean says this one is "SIP meets Presence meets Google Maps" and provides this on the Facebook apps page for a description:

"This application shows within your profile if you have a SIP device currently logged into the VoIP User server and are available to take calls. The application page also shows a Google Maps mashup page showing your current location."

There is also a thread going on in the VoIPUser.org forums about the application with more info, screenshots, etc.  It will definitely be interesting to see what else Dean cooks up.

More feedback on this one once I have a chance to actually use it.

2. Skype Me by Nabil Naghdy

This one does the rather obvious and lets you see the Skype presence of your other Facebook friends (provided they have installed the application). With a tagline of "skype meet facebook.  facebook meet skype." the developer says on the FAQ:

"SkypeMe is a Facebook application that links with your Skype account and lets you make calls right from inside Facebook. You can see which friends are online, make calls, and even buy SkypeOut credit from Facebook."

It appears to work primarily by getting the web presence of each of your friends and making that available to you, which means, naturally, that you need to enable Skype web presence inside the options of your Skype client.

There's actually two parts to it.  On your public profile page visible to everyone else, there is a box like the image shown on the left that lets another Skype user initiate a call to you.  On the internal page inside of my Facebook account for the applications I have installed, there is a page with a screen like the graphic on the right that shows all the Facebook friends I have who have also installed the SkypeMe Facebook application.

This Facebook app was announced in the Skype Mashup public chat.  Actually, I think it was really the first I saw announced (but then again, I wasn't really watching the chat last week while I was off).

Speaking of the Skype mashup contest, it was officially announced last Friday.  It will be very interesting to see what developers come up with!

Over at Skype Journal, Jim Courtney continues his exploration of the IM+ client that allows you to use Skype on the Blackberry.  As I mentioned yesterday, one of my main questions is - where is the PC making the conference call?   As Jim noted, he called me today using the client and I snapped the screenshot he uses in his post.  You can see in the image on the right that we are in a conference call.  The call is hosted by Jim's Skype client and then brings in his mobile phone and then my Skype account.

But where is that version of Skype running as Jim?  It's not on his PC.  It's not on his Blackberry.

So where is it?

Now, the IM+ client has Jim's username and password... and so I am guessing there must be a server back at Shape Services, the maker of IM+, that is running instances of Skype for each person using it.  Is that how they do it?  I would wonder how easily it would scale if this is, in fact, the case.

This all is a concern to me because it does come down to a matter of trust.  Where is that PC that is hosting the system?  How much of my info are they seeing?  If they can login as me (since I've given them my username and password) they can see all my contacts and, on a normal Skype client, all my chats as well, plus my voicemail, call logs, etc.  As the person commenting on my article yesterday noted, someone with my username/password may also have access to my PayPal account... which could ultimately lead to my bank account.  So who and where is it?

Methinks perhaps I need to go and explore the IM+ Terms of Service in finer detail...
