Voice of the Customer (VoC)

Generalized term for the overall disposition a customer has towards your company, as a result of their various touchpoints with you.

Voice-Over-IP (VoIP)

VoiP is an industry term for the technologies that allow for voice calls to be made using IP-enabled devices and apps rather than relying purely on legacy PBX hardware and PSTN technology. Calls made to or from VoiP endpoints often interact with the PSTN in some way, especially if one party is using a VoiP endpoint and the other is using an analog one. However, VoiP calls can also remain entirely on IP devices and networks.
