Some devices perform server authentication when using Session Initiation Protocol over Transport Layer Security (SIP-TLS). These devices require the CyberGate root Certificate Authority (CA) certificate to validate the CyberGate server during the TLS handshake.

Starting **July 2, 2025**, use the `Sectigo Public Server Authentication Root R46.crt` certificate.
