IP Comms

Unlock freedom, flexibility and cost-efficiency with our IP Comms offering.

What is IP Comms?

IP (Internet Protocol) voice communication uses the same networks as other digital communications, such as email and instant messaging, to transmit voice data over the internet between devices and systems.

In recent years, IP voice communication has become increasingly popular, as it offers many advantages over traditional telephone systems, including:

  • Lower costs
  • Greater flexibility
  • Integration with other tools, such as video conferencing, email and instant messaging
