Jaxtr - Voip with a twist

After my previous post on Rebtel and Jajah Megan commented telling me to check Jaxtr out. So I did that today.
Jaxtr is pretty cool and they do most of the things that Rebtel and Jajah does.
Jaxtr functionality as far as I've understood:
* People can call you for free or at local call rates from all over the world (or at least from 51 countries)
* Your friends get a local number to call you that they can dial on any ordinary phone.
* Some free minutes each month to be called by anyone (in my case, with a swedish cellphone, 6 minutes)
* Friends on some social networks as Facebook and MySpace can call you from the site directly, and still use their regular phone.
* Visitors on your blog can call you using a similar widget, and you never need to show your phone number to the world.

So far it all sounds great, but the service has some downsides as well:
* You "pay" with Jaxtr credits when you receive calls to a regular phone or mobile phone.
* You get Jaxtr credits from recruiting friends to the service, or by simply buying them. Right now the buying process isn't fullt functional and I couldn't find any rates specified anywhere.

The people over at Jaxtr has done a really good job to make widget integration on your social networks easy, and it is also very easy to invite friends from different sources (as gmail and hotmail). I'm a bit impressed of that functionality, if I ever started a voip company, I would definitely try to make inviting and social network integration as easy.

I also like the thought of being able to be reached by readers or visitors without having to give away my own phonenumber. Right now I couldn't find a timefilter for that service, which might be a problem if you have readers in another country, I don't think I'd be fun to talk to in the middle of the night. On their infopage they wrote about the timefilter, so I guess they'll implement that function soon.

What I don't like about Jaxtr is the payment plan. I don't want to be charged for receiving calls, since I can't really control how much I am called (ok, I can filter people and point my Jaxtr account to a voicemail, but I can't control how high demand it will be for calling me).
I also don't like it that the service only works for a limited amount of time each month, if I don't recruit new members or pay cash. If I put a widget up on my facebook or on my blog, I want to be certain that anyone can call through the whole month.

It's a cool service worth checking out, obviously I have. Rebtel and Jajah fit my needs better than Jaxtr, but Jaxtr's focus on their widgets makes it an interesting service to follow.

Or what about a merger between Rebtel and Jaxtr? That would be really interesting as well.
