SIPS/SRTP internal (VoIP)
Proceed as follows:
Using the Configuration Manager (Administration > Certificates)
Requirements:
internal VoIP channels that support SIPS and SRTP
suitable keys and certificates stored on the PBX (valid PBX certificate, private key of the PBX certificate, valid root certificate)
*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.
