How True Mobile VoIP For Business Works

NTA is simplifying and enhancing voice technology on mobile platforms by using the voice over internet protocol

(1) Send & Receive Calls
  • Your mobile phone will use UMTS for the voice traffic to the 3 (Three) UK mobile network operator
  • Making outgoing calls costs 2.5ppm plus costs that might occur on point 3
(2) Interconnect between the UK Mobile Operator and the NTA Network
  • This is a direct uplink to our own network
  • You will have access to all key features such as call transfer, call recording, hunt group working and internal calls
  • No further call charges occur at this point
(3) Calls to the Outside World
  • Make calls to anyone
  • You still have access to all features (e.g. call recording)
  • An add-on call charge occurs which will be the normal tariff (e.g. UK national 1.2ppm)
  • A call from a mobile to a UK national or a USA landline will cost you in total of only 3.7ppm
(4) Calls within the NTA Network
  • A call from a mobile to an extension will cost you only 2.5ppm
  • A call from an VoIP extension to a mobile extension will cost you only 2.5ppm
  • No further call charges occur at this point
