Is this another VoIP services block?

Advanced IP Pipeline reports today that wireless broadband provider Clearwire Corp. is apparently blocking outside VoIP providers from its network.

A Clearwire spokespersontold advanced IP Pipeline's Paul Kapustkathat some VoIP technologies "are problematic for wireless networks versus a wired network." The spokesperson also implied that granting open access to VoIP services such as Vonage's could tax network capacity.

Clearwire offers services in four U.S. metro areas, and expects to be in as many as 20 by the end of this year.
