Bandwidth.com is a provider of Internet and telephone services that offers a cloud-based phone system known as Phonebooth OnDemand. This VoIP solution combines hosted PBX applications, such as auto attendants, with SIP trunking, a network service that allows businesses with VoIP systems to connect calls to the traditional phone network.
Whereas pricing for SIP trunking is generally based on the usual volume of simultaneous calls that a business makes, SIP trunking from Bandwidth.com is priced according to a per-user model. In other words, businesses pay a flat monthly fee for each user, which includes unlimited local and long distance calling as well as access to PBX applications.
Bandwidth.com also offers managed broadband Internet access protected by service-level agreements (SLAs) via partnerships with major Internet service providers for businesses that need managed connections to SIP trunking services and PBX applications.
PBX features include voicemail to email, find me/follow me (which routes calls to mobile devices when employees are out of the office), conferencing and Web-based management via self-service portals.
