Cellular Gateway Tell a Friend

Cellular Gateway Products

Cut your business phone bills

Our Cellular Gateways (sometimes called a CTU ) connect to your PBX, letting you call from any extension telephone directly to a mobile phone, taking advantage of special cellular business rates by using your own cellular network provider. This unbeatable connectivity solution can so drastically reduce your calling costs that you make a complete ROI (Return On Investment) in only a few months.

  • By dialing directly to a mobile number, or using Least Cost Routing (LCR), you bypass the landline carrier and eliminate unnecessary interconnection costs.
  • By using your own cellular network provider, you take advantage of VPN and discounted cellular call packages such as zero cost calls using Vodafone's talkZoneZero.
