SIP User's Manual
Determines the device's behavior when acting as a server for
TLS connections.

[0] Disable = The device does not request the client
certificate (default).

[1] Enable = The device requires receipt and verification of
the client certificate to establish the TLS connection.
Notes:

For this parameter to take effect, a device reset is required.

The SIPS certificate files can be changed using the
parameters HTTPSCertFileName and
HTTPSRootFileName.
Determines whether the device verifies the Subject Name of a
remote certificate when establishing TLS connections.

[0] Disable = Disable (default).

[1] Server Only = Verify Subject Name only when acting as
a server for the TLS connection.

[2] Server & Client = Verify Subject Name when acting as a
server or client for the TLS connection.
When a remote certificate is received and this parameter is not
disabled, the SubjectAltName value is compared with the list of
available Proxies. If a match is found for any of the configured
Proxies, the TLS connection is established.
The comparison is performed if the SubjectAltName is either a
DNS name (DNSName) or an IP address. If no match is found
and the SubjectAltName is marked as 'critical', the TLS
connection is not established. If DNSName is used, the
certificate can also use wildcards ('*') to replace parts of the
domain name.
If the SubjectAltName is not marked as 'critical' and there is no
match, the CN value of the SubjectName field is compared with
the parameter TLSRemoteSubjectName. If a match is found,
the connection is established. Otherwise, the connection is
terminated.
Determines whether the device, when acting as client for TLS
connections, verifies the Server certificate. The certificate is
verified with the Root CA information.

[0] Disable (default).

[1] Enable.
Note: If Subject Name verification is necessary, the parameter
PeerHostNameVerificationMode must be used as well.
