The race is on to get a piece of the VoIP market

I have a guest blog post on Total Telecom about how mobile operator-provided VoIP services are hitting the headlines as players move to protect revenues from the likes of Skype. AT&T's Call International, T-Mobile US's Bobsled and Telefonica's TU-Me are all proof positive that operators are taking steps to address this competition. 

Do you think operators should offer their own VoIP services? Take a read of  The race is on to get a piece of the VoIP market over on Total Telecom and let me know what you think.
