What is meant by "SIP Trunking"?

SIP Trunking refers to a technology that facilitates voice communication over the internet using the Session Initiation Protocol (SIP). This method allows businesses to connect their voice services directly to a Voice Over Internet Protocol (VoIP) provider, enabling the transmission of voice data via an internet connection rather than traditional phone lines. By utilizing SIP Trunking, organizations can significantly reduce their telephony costs compared to conventional methods, as it eliminates the need for physical phone lines and allows for greater flexibility in managing telephone resources. This capability is especially advantageous for businesses looking to streamline their communications infrastructure while taking advantage of the speed and scalability offered by internet-based voice solutions.

The other options focus on unrelated functionalities:

• Secure data transmission pertains to encrypting data to protect it from interception, which is a different aspect of network security.

• Storing voicemail online refers to on-premise or cloud-based voicemail solutions that do not specifically involve SIP Trunking.

• Connecting multiple telephone lines is more aligned with traditional telephony systems and does not encapsulate the internet-based, cost-reducing benefits of SIP Trunking.
