2.0 TLS and sRTP
Transport Layer Security (TLS) and Secure RTP (sRTP) are additional Skype Cnnect
features that encrypt SIP signals and RTP media transported between your SIP-
enabled PBX and Skype, providing security from “man in the middle” attacks, such as
eavesdropping, wiretapping, or the theft of Skype business user credentials.
TLS and sRTP are automatically enabled for Skype Connect customers. For most SIP-
enabled PBXs, Skype Connect can auto-detect whether to use TLS only or TLS and sRTP
based on the type, make and model of the equipment that you are using to connect to
Skype, meaning that no conguration or provisioning is required.
However, in some circumstances, Skype Connect may not recognize the type, make and
model of the equipment that you are using to connect to Skype. If this is the case, you
will need to congure your SIP-enabled PBX to use TLS and sRTP. If you are unsure how
to this, please see your PBX's support documentation or contact the PBX manufacturer
for more information.
For more information on what you need to consider before conguring your SIP-enabled
PBX to work with Skype Connect, please read the Skype Connect Requirements Guide.
