Session Manager provides validation of the endpoint Transport Layer Security (TLS) certificate. This authentication is applicable to SIP and HTTP traffic.
From Release 7.0.1, Session Manager provides the ability for administrators, while authenticating SIP devices, to choose the following:
No Mutual Authentication
Optional Mutual Authentication
Mandatory Mutual Authentication
The TLS Endpoint Certificate Validation field has three options:
None: No mutual authentication occurs. There is no certificate validation and SIP endpoint cannot establish the connection.
Optional: Communication occurs if the endpoint presents a valid certificate or otherwise.
Required: Communication occurs only if the endpoint presents a valid certificate trusted by Session Manager.
a client does not provide a certificate or,
the client certificate is invalid or not trusted by Session Manager.

If you select the Required option for Pre 7.0.1 Session Manager, it results to the Optional option to support backward compatibility. |
Implementation of the new TLS validation policy supports network configuration of Session Manager 7.0 and later with the earlier versions of Session Manager or Branch Session Manager.
