What are all the pieces I need for Digital Voice (hardware, software, services, etc.)?
Businesses can implement Digital Voice between computers using nothing more than downloadable software like Pearl PC but for additional features (voicemail and audio conferences of more than 10 people, for example) you’ll want to add dedicated, for-pay business services such as Pearl Virtual PBX services or have Pearl provide an enterprise-grade IP PBX. Hardware requirements also vary but typically include headsets, IP-enabled phones, and a physical IP PBX box, if desired.
