SIPS/SRTP Settings

If IP protocol IPv6 is selected, STUN cannot be used as a NAT method either
for SIP or RTP.
The page Overviews > Ports shows an overview of the PBX ports (incoming
and outgoing).
SIPS/SRTP Settings
Proceed as follows:
• Using the Configuration Manager (page Administration > Internal SIPS/SRTP (VoIP
page))
SIPS/SRTP
Requirements:
• internal VoIP channels that support SIPS and SRTP (optional, see Important Information >
Product Details > Basic Assembly and Extensions section)
• 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.
Notes:
The certificates/keys this process requires can either be generated in the
PBX or externally, and then imported from a (PC) data storage device.
SIPS/SRTP must also be enabled in the VoIP telephones. 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.
Execute
The required certificates/keys are generated in the PBX and their accompanying information is
displayed on the page.
