Enterprise voice solutions are a variety of technologies that enable employees to communicate with colleagues, partners, and customers via voice/speech, rather than through written or visual communication. Enterprise voice systems range from traditional PRI systems which connect to the Public Switched Telephone Network (PSTN), to SIP and Voice over Internet Protocol (VoIP) systems that provide telephone connections via the Internet.
