Instead of forwarding calls from your TTNC number to a traditional landline or mobile, with the VoIP User Bolt On you can answer the call over the internet.

The VoIP User can be registered onto a physical handset, or the TTNC Softphone App for Mobile to make and receive low-cost calls with high quality audio.

Outbound Calls displaying your TTNC Number as the Caller ID can easily be made from any registered device, creating a professional image.

Combine a VoIP User with a Call Management Package to have a complete cloud based phone system, all of which is managed via myTTNC - our online control platform.

This is a great service for sole-traders, start-ups, small and home offices as well as teams of remote workers.
