SIPS / SRTP
SIPS / SRTP
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.
The following matching keys and certificates are required for SIPS/SRTP internal:
•valid root certificate
•valid PBX certificate
•private key of the PBX certificate
Note: In the end devices used (SIP phones, SIP soft clients, DECT base stations), the encryption setting must match the setting in the PBX. If this is not possible in individual cases, an exception can be set here for the end device:Telephones > Assignment > > RTP encryption
Important: To change a certificate, SIPS/SRTP must be switched off. When switching it on again, it may happen that calls are interrupted.
