CallControl = Hosted PBX + Fully Managed Telephony Service

Discover how it works & what you get

What is VoIP & PBX? How does it work?

Voice-over-Internet-Protocol (VoIP) is a technology for making calls over the internet rather than the analog phone system. VoIP converts sound into digital voice data and then transfers it over the internet. VoIP’s digital nature offers powerful potential for call  optimization. Internet calling rates to landlines & mobile phones, domestic or international, are much cheaper than conventional calling rates.

VoIP technology has advanced by leaps and bounds in recent years. All you need is a high-speed internet connection to enjoy our crisp, crystal-clear call quality, at all times & with minimal bandwidth requirements.

PBX stands for Private Exchange Branch and basically means 'phone system'. Today's PBX's are often based on software, not hardware. A modern PBX is a central system with many features to control call routing, and it connects user devices to telephone networks (in the case of true VoIP, via the internet).
