7.2. Client Certificate 
OpenScape Mobile Pro provides a mechanism for installing a TLS or MTLS Client certificate, which is issued by a trusted authority, in order to authenticate the client (OpenScape Mobile Pro) to the server.
INFO:
MTLS refers to Mutual Transport Layer Security – A form of TLS where the transmitting
party
requests the client’s credentials. If both parties can establish trust
in the other then the connection is called mutually authenticated – also
referred to as client authenticated. This adds another layer of security
by authenticating the client party too.
IMPORTANT:
In case of a SIP MTLS connection, only the last imported certificate is used.
The mechanism consists of two parts:
-
Client certificate DistributionSystem Administrator has to distribute the Client certificate via e-mail.
-
Client certificate InstallationOpenScape Mobile subscriber securely stores the Client certificate on the device.
By requesting the Client certificate, the server is allowed to authenticate and validate
the
client, so that the secure connection between client and server can be
established.
