The battle between Truphone, a mobile VoIP service provider and T-Mobile UK has turned ugly and is heading to the court. T-Mobile UK is refusing to interconnect with mobile VoIP provider Truphone. Truphone has asked the UK courts for an interim injunction against T-Mobile UK. The case was heard by a judge at the Royal Courts of Justice, London. Some of our commenters let us know that the problems of Truphone might be company specific, for other services seem to connect with T-Mobile UK.
