VoIP makes it possible to transmit voice over any private or public IP network via a wired connection (ADSL, fiber optic) or a wireless one (Wi-Fi, mobile networks, etc.).
Although it’s based on VoIP, ToIP (Telephony over IP), only transmits voice over local IP networks (LAN).
What is hosted VoIP?
Hosted VoIP, or cloud VoIP, is an IP telephony solution available online and accessible via servers. It’s different from on-premise VoIP, which requires the installation of telephony infrastructure in the company’s local network.
