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

• 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

• 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

• 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

• 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
• Presence status of your mobile extension (BLF - Busy Lamp Field)
• No further call charges occur at this point
