The Contrex Mobile VoIP service uses the capability of the (O2) mobile network, rather than running on the data connection. This ensures a higher quality of service, seamless integration with the mobile device, as well as a better all-round user experience. Multiple DDI numbers can be made available on the same device, with 01, 03, 08 or 07 numbers available.
