    Mobile VoIP apps importance can't be denied at all. They have many benefits and provides a lot of functionalities. Optima Dialer is one of the best of these apps. As explained above it can even work with the lowest bandwidth. It proves to be the best VoIP App out there.

    I will personally not prefer VoIP apps for professional usage. These apps can't be trusted for business communications. We can't trust these applications at all, no matter if these are Paid or Free. I only use these apps for personal use at home.
