SIP is an integral part of VoIP systems as it allows calls to be set up, managed and terminated. Although SIP is closely related to VoIP, they are not identical. VoIP refers to the transmission of voice over IP networks, while SIP is the protocol that enables the control of communication sessions.

Cloud telephony allows users to use their extension across different devices, including IP phones, smartphones, tablets, or computers with appropriate softphone software.
