Making Cheap VoIP calls through Rebtel is just not such a difficult task, plus its all broken down in to steps and you would likely learn about them right on the website.
Last but certainly not least, VoIP providers do not charge hidden fee's. Hidden fee's can make up to 20% of your total monthly phone bill. The only extra fee with VoIP is a 3% federal excise tax based on usage.
Check what else you may be expected to pay for. Look, for example, for set-up fees, administration fees, cancellation fees/policy, refunds policy, equipment costs etc. Does the VoIP provider try to hide these? Or are they clearly spelled out, which suggests that the provider is committed to transparency?
Because of the underlying technology (the SIP protocol), you can easily hop from one vendor to another. Vendors charge hefty fees for additional phone sets, especially once the phone models get older. With VoIP, if you're not happy with one vendor, just switch to another and never be locked in anymore.
This is the 2nd major use of VoIP. You can "connect" to your office phone system from anywhere there is a high speed internet connection. Using a special VoIP telephone or a Laptop "soft phone" you can work from home or a hotel and it's just like being in your office. You have access to all your phone system features including the intercom, paging, all outside lines, voice mail, and even your extension can ring on your Business Phone Service. Best of all, you don't lose the use of your computer. 1 high speed internet connection can run your VOIP Phone and your PC at the same time.
Make sure that the provider you choose has competitive pricing. While this is true, you don't want voip phone service anything too cheap. If you go the low end route you are probably going to get a really poor phone service. You do not want that. You'll get dropped calls and have to call customer support all of the time.

So these are my Business Phone Service CONs, but one particular VOIP Phone Service Provider they give you solutions to these 2 problems.
