Broadvox, which has one of the most robust platforms in VoIP has announced a comprehensive reseller program.
Reseller programs are what built MCI and SPRINT years ago, and are used by the likes of CISCO and many hardware companies as a way to extend their sales force. Broadvox, which is not really a newcomer to the VoIP game, may be one of the companies that actually makes it to the point of being a major part of the VoIP game. They are very active on the net with participation in leading online bulletin boards and seem to have a very well thought out plan.
This is certainly one company to watch, amongst the many cluttering the field behind Vonage and ATT's CallVantage.
