What are VoIP Service Providers (VSPs)?
VoIP Service Providers (VSPs) are the next generation telcos that provide interconnection between VoIP and PSTN networks. They allow call origination and termination between these two networks. Some of the more popular service providers include Vonage and Broadvoice. However some service providers require you to use the VoIP hardware that comes with the purchase of their service (Vonage uses “locked” Linksys PaP2). We reccomend you use a service provider that is more flexible and allows the user to bring their own device. For this reason we like Broadvoice because they are compatible with VanAccess IP Phones, VoIP gateways, and Small Business IP PBX Systems.
