SIPS/SRTP
Proceed as follows:
• Using the Configuration Manager (page Administration > Internal SIPS/SRTP (VoIP))
SIPS/SRTP
Requirements:
• internal VoIP channels that support SIPS and SRTP (optional, see Technical Data in the Instructions)
• suitable keys and certificates stored on the PBX (valid PBX certificate, private key of the PBX certificate, valid root certificate)
Internal VoIP call connections are encrypted to prevent listening in. The connection setup and termination, and also call signalling, are encrypted with SIPS. The call data is encrypted with SRTP.
Note: The certificates/keys this process requires can either be generated in the PBX or externally, and then imported from a (PC) data storage device. Note: SIPS/SRTP must also be enabled in the VoIP phones. In addition, the certificate must be verified. For this, you may need the Fingerprint.
Important: SIPS/SRTP must be switched off before you can change a certificate. When switching it on again, it may happen that calls are interrupted.
