Regardless, time to ask the community what kind of a VoIP users are you? Cable kind, or someone who uses soft clients or do have still doing the Vonage styled ATA-based VoIP calling?This cuestions finally made me get a general idea about all the services I use. And, god, it's a lot of them!
Actually I am using 20 VoIP accounts, out of couriosity and because of the different services they offer. But maybe I am subscribed to even more, but just forgot it. My goal is to make free calls and use arbitrage possibilities between the different VoIP services. I use the different VoIP providers on my desk phone that's connected to the Fritz!Box fon ATA and on my mobile phone, Nokia E61, that can hold several SIP accounts. Also I use Fring on the E61, because it can hold my accounts on Skype, MSN messenger, Google Talk and also one SIP account.
Here is why I use so many different services:Voipstunt: For free or super cheap calls worldwide. This services I use most. It's installed on my desk phone and on my mobile phone, Nokia E61. So I can make free calls from Wifi hotspots.
Sipgate: Is use Sipgate as an answering machine. Incoming calls to my ATA are forwarded for free to the Sipgate mailbox if not answered in 30 seconds. For that purpose we have two Sipgate accounts at home.
Tpad: Because of their BreakIn numbers worldwide. My friends from Peru can call me so in Berlin for the cost of a local call without having a computer.
Truphone: To check it out on my mobile phone and because of their new offer that gives me landlines nearly worldwide for free in the next two months.
Several services for testing purposes and out of couriosity: GMX, Voipbuster, FWD, dus.net, Sip2sip.info, Ekiga.net, Openwengo, iptel.org, Rebtel, 4S newcom ...
Voxalot: Every time my Fritz!Box fon ATA gets too full, because it can only hold 10 VoIP accounts, I move the one I don't use to call out anymore to Voxalot. This service works like an ATA in the net: It's logged in to the VoIP services I don't use so much anymore. So I can keep them and receive calls on their SIP addresses or phone numbers. For instance if somebody calls my unused Gizmo account (I have several of them) my Voxalot account in my Fritz!Box fon ATA rings.
Gizmocall: I have set up a special web link to my address at Gizmo Project. So people can call me unlimitedly from a web page.
Ageet: That's probably the world's smallest PBX. It works as a Activex plugin in Internet Explorer and has a link from my website. If people open this page the PBX loads and they can call me from their browser. This was really cool until I discovered Gizmocall one week later.
The large quantity of the services I use is not so much a sign that I might be tech crazy. It's just an indication of how much the VoIP sector is still evolving. The industry consist of thousands of different companies that offer basically the same: Cheap phone calls over the internet. But if you look closer you see that they differ in the added services: cheap break in numbers, calls from a website, use the old PSTN number as VoIP number, administrate your other VoIP accounts,...
So probably I will have soon 30 VoIP providers. For instance I am interested in a Peruvian VoIP number that my friends in Lima can call for price of a local call. Tpad is already doing a good job with their callin number and the extension. But sometimes this does not work and a real Peruvian phone number would be much more elegant. But still the Peruvian VoIP market is underdeveloped and these numbers are too expensive to me.
