The Avaya Equinox® Client uses two protocols to communicate with the Avaya IP Office: Transport Layer Security (TLS) and Transmission Control Protocol (TCP).
TLS: is a security protocol that provides communications privacy over the internet. It is used to secure the connection between the Equinox client and the IP Office.
TCP: is a transport protocol that is used to establish a reliable connection between the Equinox client and the IP Office. It provides a mechanism for error checking and data retransmission, which ensures that data is properly transmitted between the two systems.
