Jeff Pulver: Open source software communications will begin to influence the VoIP market in a big way next year, according to Jeff Pulver, who heads the industry standard VON (Voice on the Net) conferences and publications. In his predictions for 2005, Pulver also said some VoIP start-ups will flame out while others will launch IPOs. In addition, governments will take harder looks at regulating VoIP and Congress will consider rewriting the Telecommunications Act of 1996 with an eye to VoIP.
