Enterprise VoIP


Enterprise VoIP services are enterprise-grade versions of residential VoIP and business VoIP solutions that provide large organizations with advanced features and functionality such as private branch exchange (PBX) capabilities, conference calling, desk-to-desk calling, music on hold and automated attendants.

Enterprise VoIP offerings may also offer an additional level of security such as IPSec encryption, Voice over Secure IP (VoSIP), Secure Voice over IP (SVoIP) or Secure Voice over Secure IP (SVoSIP) to help protect confidential VoIP communications.

As with all VoIP (or Internet telephony) solutions, enterprise VoIP utilizes packet-switched telephony to transmit calls over the Internet as opposed to the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN).
