A study conducted by Sandvine Incorporated in November and December 2005 shows that broadband service provider-branded VoIP rollouts were extremely successful in 2005 and have taken the lead in terms of share of VoIP minutes.

The new study indicates that North American service provider-branded VoIP represents 53% of all VoIP minutes on broadband networks. Vonage, with 21.7% share of North American minutes and Skype, with a 14.4% share were the two leading third-party providers. All other third-party VoIP providers captured the remaining 10.9% share of minutes.
