For multinational customers RingCentral offers software as a service, where customers provide their own local telecommunication carrier services (“Bring Your Own Carrier” or “BYOC”). BYOC allows customers to receive the cloud PBX functionality of RingEX, by connecting their existing local voice carrier to the cloud PBX functionality, which includes videoconferencing, team messaging and file sharing services. All calls to and from the Public Switched Telephone Network (“PSTN”) travel over the local voice carrier’s network via a gateway purchased and owned by the Customer (the “Gateway”).
