VoIP is Voice over Internet Protocol. It’s a general term used to describe voice communications over a packet-switched network (such as the internet). In this article I’m going to touch on the several different ways you can use PC-to-PC VoIP.

Important note: Yes, VoIP obviously includes the ability to communicate via PC-to-phone and vice versa. But that costs money to do that in most instances. PC-to-PC calling is completely free and that’s what I’ll be talking about.

Also note: There are more than 5 ways to VoIP. This is just a quick list.

Skype

Web site: www.skype.com

This is by far the most used PC-to-PC VoIP software that people use. In fact it’s used so much that the name is used as a verb that means "to call" (ex: "We need to talk, I’ll Skype you") much the same way Google means "to search the internet".

Skype also makes for a darn fine text instant messenger as well.

The only bad part about Skype is that it uses a proprietary protocol, meaning you must use Skype software in order to use the service. This is a turn-off for some.

Is there a way to call a Skype user without Skype software on a PC? Yes. There’s Gizmo5’s OpenSky. I haven’t tested this so I don’t even know if it works, so if anybody wants to give that a go, please feel free to do so and comment below if it worked or not (and if it did work, how well did it work?)

Windows Live Messenger

Web site: download.live.com/?sku=messenger

WL Messenger has had the ability to do VoIP for some time now, although most people aren’t aware of it. This is mainly because for whatever weird reason it’s hidden.

I’ve found the easiest way to access the feature is to open the messenger, press ALT on your keyboard to bring up the top menu, then click Actions, Call, Call a contact’s computer, like this:

From there you can place a call to another WL messenger contact on your list.

Yahoo! Messenger

Web site: messenger.yahoo.com

Calling another contact on your list is easy in Y! Messenger. Just right-click an online contact and choose to "call" the user’s computer. No fuss, no muss.

Google Talk

Web site: www.google.com/talk

Out of all the software on this list, Google Talk’s is the easiest concerning PC-to-PC calling. It’s as easy as Yahoo’s way of doing it but has the advantage of being very light on system resources. As a VoIP client, it’s tough to beat how straightforward and simple Google Talk is.

Ekiga

Web site: ekiga.org

Linux users are familiar with this one, but bear in mind there is a Windows version also.

Be sure to read Ekiga Interoperability as it explains what will and won’t work with Ekiga on phones, Mac and Windows.

What’s the best of the lot?

Skype, no question.

Why is it the best?

1. It will work easily on Windows, Mac or Linux.
2. It has the most recognition as a solid PC-to-PC software voice client.
3. It’s the easiest to do small voice conferencing with (meaning 6 participants or lower before the connection chokes).
4. The software runs well even on lower-end PCs and Macs.
5. For what it offers for free, it’s extensive and moreover useful.

Do you use VoIP at all? If so, what’s your favorite VoIP software client?

Putting instant messaging on your web site has never been easy. The only way people could get any messaging on their web sites was to use IRC. The popular way to do it was to embed a channel such as with PJIRC. And later on there was the ability to create an IRC chat "widget" with Mibbit.

Both methods are so-so at best because they rely on IRC servers that periodically have netsplits, kicking you off your own channel. IRC for messaging is an imperfect solution at best.

These days however there are two super-easy ways to get IM direct on your site that is true IM and not IRC.

Yahoo! Messenger Pingbox

This creates a small widget-style box that you embed direct on your web site. It does not reveal your Yahoo ID (big plus). In your Yahoo! Messenger you will see a new "friend" category for the Pingbox you create.

Pingbox allows for any color customization you can think of, three different text sizes and emoticon support.

You use Pingbox just as you would with any other Yahoo! Messenger contact that’s on your contact list.

IMPORANT NOTE:

Pingbox will not work unless you specifically have Allow Yahoo! web sites to show when I am online checked in the messenger client.

To see if you have this enabled or not, launch Yahoo! Messenger, then click Messenger then Privacy.

You should have the "allow" box checked, like this:

If you don’t, check the box, then close and restart Yahoo! Messenger. Pingbox will start to work after you do that.

Meebo Me Widget

Meebo is known as one of the best in-browser instant messengers there is. Something else that it offers is the ability to create custom IM chat widgets for your web site.

To create a widget, login to your Meebo account (if you don’t have one it’s free to register), click preferences then meebo me widgets, like this:

From there you create your widget.

Like Yahoo! Messenger Pingbox, you can configure it to say any name you want and not reveal your Meebo username.

Meebo Me widgets are not as fanciful as Pingbox, but definitely get the job done.

In addition, if you want a way to chat without having a Meebo session open in the browser, just use Meebo Notifier. This will put a small icon (in Windows) in your taskbar. Whenever you receive a message you’ll get a toaster pop-up where you can click and reply.

Why would this be useful?

Here’s a few examples:

• For a gamer that runs a guild that wants an easy way for people to contact you without revealing your IM screen name.
• For a small biz owner that wants a free solution for direct-IM contact with customers that looks nice and works.
• For anyone that wants a universal solution for IM that doesn’t require anyone to use any specific IM service.

I’m sure you can think of a few more, but you get the idea. Having easy ways for people to IM you without the need for specific clients/services is good to have.

AIM is the primary instant messenger I use. Out of all the IM services I’ve used over the years, it is the most reliable. In addition, it runs flawlessly on any operating system. Whether you’re on Windows, Mac or Linux, you can run AIM.

The latest client offering on the Windows platform is AIM 7 Beta 2.

Short review:

It’s awesome. If you use AIM, get it.

Long review:

This is best given in points.

• If you run multiple computers at home, you can run it on each computer at the same time. Previously I was only able to do this with AIM Lite.
• Following in the footsteps of AIM Express, messages from those not on your contact list will prompt a window asking if you want to chat with them or not. Previously this wasn’t there.
• Linked accounts work great. In addition, you can have them all set to invisible on login instead of having to set each individually.
• The interface is a whole lot cleaner and a lot less "cartoony" (something Yahoo and Windows Live suffer from in abundance).
• "Me" tab makes it super-easy to manage blocked users in just two clicks (you had to really dig for this previously).
• Integrates with Facebook and Twitter easily with new "Lifestream" tab.
• Integrates with Delicious and YouTube.
• Runs light and doesn’t eat up memory.
• I tested on my XP laptop and Win 7 PC. Runs great on both.

AIM 7 is full of awesome stuff. If you use AIM, you will really like this client.

Lots of us have more than just one computer in the home. And with instant messenger apps, that unfortunately means only one computer can use a single IM account at a time.

For example, if you use Yahoo Messenger and login to one PC in the home, then use the same account to login with on another, it will "kick off" the first one.

You can have multiple logins per single account on just about any messenger service, but it’s all dependent on what software you use.

AIM

The AIM service does allow multiple logins per single account. The best software to use to take advantage of this feature is AIM Lite or Pidgin.

AIM Lite by default has this enabled, but with Pidgin you have to check a box:

…and then you’re good to go.

Windows Live Messenger

The current version of WL Messenger does allow simultaneous logins. There should be no special setup necessary to make this work, however the only drawback is that you must use the same software on all computers that connect.

For example, if one PC uses Windows Live Messenger and the other Pidgin, WL Messenger will boot off Pidgin and vice versa.

Everything else

The absolute easiest way I have found to have same-account logins on multiple computers is by using the Meebo Notifier. This is Windows-only software but it works fantastic. The app acts as a gateway of sorts to the web interface, but has a nice n’ tidy icon in the taskbar to notify you of new messages on as many computers as you want.

Meebo will configure any IM account you can possibly think of.

The only drawback I found is that if you put one of the computers in hibernation (typical for a laptop), it will log out Meebo on the other PCs in your home network. But other than that it works flawlessly.

And yes, this is a bit of a hybrid between web-based IM and client-based, but it does work and that’s the whole point.

What about Jabber?

While it’s true Jabber will allow a "login as many times as you want anywhere" type of IM, setup is annoying for non-XMPP messaging services.

In Windows (or Mac OS X or Linux), you’d most likely use the Psi messenger which easily allows for XMPP connectivity. But after than you have to find a Jabber server that allows for non-XMPP IM service "transport", and that’s the annoying part.

So you go to the Jabber server list, connect up to a server, perform a service discovery and see if the protocol you want is available for transport. If it’s not available, you have to move on to the next server. Hunt, peck, hunt, peck.. it’s annoying. And there’s no guarantee the server will be there tomorrow or even prove to be reliable when working.

Jabber is truly awesome. I’m not kidding. This is why Google Talk uses that protocol. And it would be great if all other IM services adopted the protocol as well. But that isn’t the case currently, so we’ll have to stick with what’s useful for us.

Web-based instant messaging is something some people swear by while others (like me) still prefer the client.

Meebo, one of the better multi-service web-based IMs, now has a Windows app called Meebo Notifier that can run the service without having the browser running, sort of.

I say "sort of" because while it is a legitimate app that takes care of authentication, gives toaster pop-ups for new instant messages and so on, it still has to launch the browser when you want to actually chat. Even though that’s true, some of you out there may like this.

Meebo Notifier is small and installs itself as a small taskbar icon. It’s distinctive because it’s orange (but still looks decent, not to worry). When you have messages waiting/incoming or other events, the icon changes to an orange ring and flashes politely for a few seconds (i.e. slowly), then stays as the O until you clear notifications or double-click the icon to see the messages.

One of the best part is that you don’t have to use a Meebo account.

Here’s the login screen for the app:

I can choose just one IM service if I want instead of the Meebo account (which launches all IM accounts you have configured). In fact you don’t even need a Meebo account to try it – and that’s cool.

When logged in successfully you get a toaster pop-up:

Note the orange Meebo icon.

Above, when you get a message, the icon turns into an orange ring and a pop-up appears for a few seconds (or until you close it).

Above, right-clicking the icon gives you the option to clear notifications, set preferences, exit and so on.

Above, when you close the browser, you get this notice. Meebo is still logged in even with the browser closed.

Said honestly this is really good.

My biggest complaint? No sound options. It would be really nice if there were a small WAV you could choose when notifications come in. Other than that it’s tough to complain about.

Try it out, you may like it.

The long (and I mean long) awaited Trillian Astra from Cerulean Studios was made available to those who were willing to sign up for testing purposes. I downloaded it today and installed it. Currently it’s just Windows-only for testing purposes.

Trillian was the first multi-protocol instant messenger I ever used years ago when they were at version 0.74, and for a long time Trillian was the only multi-protocol IM game in town. The currently available public version is version 3.1.12. The Astra version I have is version 4.0 Build 101.

With version 4, the look is different and a notable improvement. And it also supports more protocols. In addition to what it had before, it now supports social network stuff like Facebook, MySpaceIM, Skype and Twitter.

Two opponents Astra would have to overcome are Digsby and Pidgin. Both of these do just about everything Astra does.

Pidgin, while nice, is a bit clunky it its operation. It’s not that it doesn’t work, but it does need some work in the user interface department. In Linux, Pidgin seems to look and work better. In Windows, not so much.

Digsby looks good and performs good as well. But it is a memory muncher.

Astra’s advantage is that it looks better than its competitors, eats up the least amount of memory and does not require any huge learning curve to use it. In fact, Astra could even give Adium some competition if a Mac version is released.

But is Astra too late to the game to make a real splash as a new multi-protocol IM client? It might be because there really isn’t anything new here that the other guys don’t already have. And when it comes to multi-protocol IM clients, people don’t like to switch. The only time anyone changes clients is for features they don’t have with one they already use. And even though Astra looks good, it may not be enough to switch people over.

However.. there is also going to be a web-based version of Astra as well, something neither Digsby or Pidgin has. This means what’s in the client is also accessible on the web no matter where you are. No need to bounce between a client and Meebo sounds quite nice.

Astra is a solid well-thought-out program. It has the look and feel of a modern application, runs great on XP and Vista, it’s easy and has all the makings of a winner.

The largest drawback? This will most likely be a paid application. And that lets Pidgin and Digsby stomp Astra to oblivion. That is unless there’s a free version of Astra like there is for Trillian 3.1.12 at present.

In most enterprise environments the mail server used most often is Microsoft Exchange. This has been the de facto standard for many years. Corporations like it a lot because not only does it do mail but a ton of collaborative features as well. When connected via the Microsoft Outlook client, it is truly a powerhouse setup.

Wondering if there was any Linux messaging platform that would fit the bill as well as Exchange (or at least put up a good fight), I searched around and did in fact find something on the Linux side that’s not too shabby:

Scalix.

There are a few things I like about Scalix up front.

The enterprise version is not free (although the Community Edition is). I appreciate the fact that Scalix has a paid enterprise version because the fact of the matter is that enterprise cannot run solely on community supported stuff. Enterprise is a business after all, and where there’s money to be made, money has to be spent. Paying for an enterprise-class messaging platform is worth the money.

This is truly enterprise-class messaging we’re talking about. This is not some haphazard badly-designed mish-mosh of code. Rather it’s something that took a lot of time and effort to put together.

The fact Scalix works with Evolution, iCal, Thunderbird, MS Outlook and more is a huge plus.

I seriously dig the fact Scalix explains (even if in basic terms) that the TCO is worth checking out – particularly the last paragraph titled "Transition Seamlessly." The biggest gripe about switching over to anything in enterprise is the migration process. It is never easy, but at least Scalix went thru the effort to ensure the migration will be as headache-free as possible.

It’s the migration notes that really caught my eye here. Most Linux advocates are usually of the opinion "You’re just used to Microsoft, just switch and figure it out", which as anyone with a brain realizes is a stupid maneuver. Migrations have to be planned carefully and timed just right. Scalix even went so far as to say (more or less) "Hey, if you’re using Exchange right now, don’t worry – we’ve got tools to migrate you over."

I wish (oh do I ever) that Linux distribution OSes were more like this, as in the kind that give you a sense of confidence if you want to make the jump.

Remember the Community Edition listed above. If you’re interested in running your own enterprise-class mail server, it’s free for download if you want to check it out. Granted, you don’t get the perks of the enterprise edition, but hey, enterprise-class only a download away? Not bad if you asked me.

AOL Instant Messenger, better known as simply AIM, is my preferred way of instant messaging simply due to the fact it’s the most reliable chat network. Out of all the things AOL does wrong, AIM is the only thing they do right.

Windows Live (formerly MSN) and Yahoo both have routine small outages on their networks that can get really irritating really quickly – but this doesn’t happen on AIM. Ever.

And for those that say "What about Google Talk?", yes, GTalk’s Jabber way of doing things is extremely reliable but unfortunately doesn’t have as much of an established presence like AIM does.

AIM Lite is an AIM chat client released the AIM team themselves. It is available for both Windows and Mac. AIM Lite one of the absolute fastest and lightest graphical clients I’ve ever used. The fastest I’ve ever used was Miranda, but AIM Lite comes darn close.

For those who are all about speed (or if you just have a slower computer) and use AIM, I strongly recommend getting AIM Lite.

If you like the software, see the plugins available. These plugins add in features like sound notification, toaster pop-ups (the good kind of pop-up) and a few other options.

I’ll answer that question even before I start this article: Yes, you are. And you always have been since the first time you used text messaging on a mobile wireless network.

The reason you’re getting screwed is because those who are computer savvy even to the most basic degree understand that when you charge 20 cents for 140 bytes of data or less transferred, that’s nothing short of the rip-off of the century. More on that in a moment.

According to washingtonpost.com, all the major phone carriers deem that outside of the flat-rate monthly data plans, a text message costs 20 cents each time one is transferred.

Let’s examine that for a moment.

If you take a 140-character phrase and save it as a text file on your computer, you will see that text file is 140 bytes exactly. One byte per character.

Let’s say you live on your cell phone and send 500 text messages daily (yes that’s extreme but there are some crazy fools who actually send that much), with each being a full 140 bytes each. That’s 70,000 bytes daily or 68.4 kilobytes.

If you sent that much text messaging data every day for a whole month, that’s 2 megabytes of data. That’s it. Just 2. For the month.

You’re probably thinking "I can download more than that in a web browser in less than 5 minutes." That’s right.

Now realize that most people don’t get anywhere near 2 megabytes of plain old text data transferred per month. We’re not even talking binary transfers here, just text and text alone.

You’ve probably figured out by now that 140 bytes isn’t worth 20 cents no matter how you look at it. No way, no how. It’s an outright ridiculous price.

Consider the following (this is from the linked article above):

…600 text messages contain less data than a 1 minute phone call. It said that at 20 cents a text message, wireless carriers would collect $120 for 600 messages.

"Does $120 for the equivalent of one minute of voice seem reasonable?"

I personally don’t think that’s reasonable.

Do you?
