One of the most important factors in choosing a VoIP provider is ensuring that they offer the 911 service. Sure most VoIP carriers offer E911 service, but not all of them. So check first if the VoIP provider offers E911. Now if the VoIP provider does not have E911, then make sure that you have either a cell phone or a customary landline available in case of an emergency. Also keep in mind that when you take your VoIP phone when traveling, then E911 will not be able to track your location since you are away from your registered address.

International calling should also be considered. If you do a lot of international calls, then you should do a bit of research on International Rates since they differ depending on the provider. Remember that there are some carriers who offer unlimited calling to some countries.

Lastly, you should also see if the provider offers a Money Back Guarantee. Keep in mind that VoIP is a new product and most VoIP providers will surely offer a free money back guarantee. So make sure that you check with each provider. The money back guarantees might vary from a 14-day to a 30-day money back guarantee. You should also keep the original packaging that came with your equipment just in case you need to send it back.

Now this is just a brief list and there are still a lot of things you need to consider when you’re choosing a VoIP provider. Remember that an educated consumer usually gets better results.
