Most providers allow you to call any phone number in the world, whether that number be a local, long-distance, mobile phone, or international number. However, some computer-based providers may limit you to other subscribers to that service (Commonly known as “User to User”). For your convenience, we list only those providers who allow their customers to call the regular phone network. Additionally, you may be able to speak with more than one person at a time using a feature typically titled either “Conference Calling” or “Three-way Calling.”

No, you do not need a computer for phone-based VOIP services. An adapter (often provided free of charge by the VoIP provider) connects the phone to a high-speed internet connection. A computer can be helpful to utilize and manage different features offered by the provider; however, it is not needed.
