# Innovative telephony with AI Agents and appointment bookings

Whether it is plain old *0 cost international calling* or a fancy *AI Agent* that brings you to the VoIP telephony - it's all covered on VoIP Number. From super useful regular VoIP telephony features like a *Ring Group* that calls few extensions in a sequence or simultaneously - to innovative things like *real time speech translation*.
