Six Questions With Truphone’s Keith Wallington

Keith, as his title reflects, is responsible for international operations at Truphone. For those who are not familiar with Truphone, Truphone is a provider of mobile VoIP services to the masses. What follows is our summary of conversation.

In the context of Truphone, mobile VoIP is the transmission of voice telephony over a wireless bearer (typically Wi-Fi). Truphone has deployed a complete mobile telephony core network architecture based on IP: the IP equivalents of an HLR (Home Location Register) and MSC (Mobile Switching Centre).

The Truphone service treats the public wireless Internet (Wi-Fi) as the access bearer.
