The boss at T-Mobile says he doesn't think wireless VoIP is going to be as big a hit as computer-based VoIP. Hamid Akhavan, CEO of T-Mobile International, told a reporter at the 3GSM World Congress that mobile VoIP has a bunch of issues to overcome, among them the resolution of IP addresses, emergency service and pricing. The good news (for him): he doesn't think that mobile VoIP is going to hit his bottom line very hard. Between what he anticipates will be a low pick-up rate and the money he'll make from selling data plans, he might be right. Remember, Skype promised a year ago that they'd have a mobile client, but confessed recently that development was proving much more difficult than expected [1].
