    Does maximizing your business telephony powers while reducing costs sound interesting to you? If so, shifting to VoIP is a one-way option. Enjoy competitive domestic/international call rates accompanied by the lowest fixed charges in the market.


What is VoIP?

“Voice over Internet Protocol” term speaks for itself. In short, VoIP deploys a calling process over the internet in approximately the same way as well-known apps such as Viber. Upgrade your business telephony capacities (mobility, scalability) without the restraints and costs of traditional landlines just by adopting a VoIP solution.



Why switch to VoIP telephony?

  • Low fixed costs, only €15/year.
  • The lowest calling rates for domestic outbound calls (*mobile and fixed*).
  • Affordable international calling rates (*with no roaming fees*).
  • No need for upfront hardware investments.
  • Greek numbers from any geographical location.
  • International phone numbers from any country.
  • Your fixed number can move along with you since your connection is virtual.
  • Communicate via any device with a speaker, microphone, and access to the internet.
  • Enhance remote abilities: redirect office calls to your mobile.
  • Add extra channels (trunks) to make or receive multiple calls easily.
  • Upgrade your business communications by combining modulus VoIP with modulus vPBX.
  • Get a number in 1 day.
  • Smooth transition from conventional telephony to VoIP. Internet access and a modulus VoIP subscription are the only things you need.
  • Number Porting: Of course, you can maintain your phone numbers and transfer them to the modulus network.
