Wholsale VoIP
VoIP technology is a modern substitute for traditional telephony systems, converting analog voice signals into digital data packets. These packets can be transmitted over broadband IP networks, thus enabling phone calls over the internet instead of conventional PSTN networks.
-
As a wholesale VoIP provider, businesses acquire essential resources like SIP trunks, phone numbers, and platform capabilities in bulk from carriers such as Bandwidth or VoIP.ms at wholesale rates. These resources are then resold to resellers or business customers under the provider's brand and packages, often at a markup.
