Is there a safe way to choose a VoIP service? Yes, but it does take some work and careful research to make sure that you don't get stuck with something you cannot use or worse yet, be forced into a scenario in which your telephone communications is impaired.

There are 3 general steps to choosing Broadband Phone service.
1. Qualify Yourself
2. Qualify a specific Provider
3. Research the provider.

1. Qualify Yourself
Ask yourself "why do I want voip?" Is it because you want to save money? are you attracted to voip by all of the features that it offers? Maybe you're sick of your local telephone company. Whatever the reason, make sure that the benefits are better than what you're already getting now.

2. Qualify a Specific Provider
Your voip provider means everything when it comes to reliability and sound quality. You should choose a provider that has the features that you need (call waiting, 3 way calling, extra lines, distinctive ring, etc.). One thing to definitely look into is the 911 service that's offered and don't be afraid to ask lots of questions to the customer service department of the prospective provider. Number portability (if you need to keep your old number) is something else to be looked into. The rates should be competitive and don't forget to look at international rates if you do any international calling.

3. Research the provider
Just because everything looks OK from a customer service angle, the service is cheap , and does what you need it to does not necessarily make it a good service. What does make a service good is if they have happy customers. The best way to do this would be to search the better business bureau for complaints against the company.
