It's clear that many VoIP companies aren't meant to be standalone telecom businesses – they function far better as providers of features and capabilities to other telecom businesses. The latest example of this is SabSe Technology's acquisition of Mobivox. Although Montreal-based Mobivox offered cheap VoIP calling services of various types, what set it apart was its so-called voice-activated user interface, or VUI. The interface let users dial by speaking rather than pressing keys – a significant benefit for mobile talkers. The addition of this capability will boost the attractiveness of the array of services SabSe is offering worldwide.
