Vodafone is looking at some legal troubles for trying to stop VoIP. James Tagg, Chief Executive of Truphone claims that Vodafone is failing to meet interconnection obligations, blocking competitor websites and disabling internet telephony. He also claims that Vodafone blocks calls coming to their customers from people using Truphone services. Vodafone’s official stance is that VoIP services do not have quality guarantees and therefore their customers may be disappointed with the experience. For now the controversy is still brewing but as technology progresses these details will have to be ironed out.
