Parameter Description

Use TLS Select Yes or No to enable or disable secure

transmission.

TLS Listening Port Enter the port number used by XT Series for receiving

secure inbound SIP calls. By default, the system uses

port 5061.

Disable TLS 1.0/1.1 Select to disable TLS 1.0/1.1.

Verify Certificate Select Yes to connect to other devices via TLS only when

the other device has certificates signed by a CA

recognized by XT Series.

Select No to connect to a device whose certificate has

not been validated.

Certificate Hostname Validation Select Accept Validated Only to ensure that only

certificates with validated hostnames are accepted by XT

Series. This is the default policy for certificate hostname

and key/extended key usage validation.

Select Accept Validated or same default certificate to

accept certificates which are validated or which are the

same as those currently used by the XT Series.

Select Accept All to accept certificates without

performing a hostname validation.

Verify Certificate Key Usage Select Yes to ensure that the XT Series only accepts

certificates if a ‘Key Usage’ or ‘Extended Key Usage’

value is validated.

Select No to accept certificates without performing a ‘Key

Usage’ or ‘Extended Key Usage’ check.

Verify Certificate Revocation Select Yes always to ensure that the XT Series checks if

the certificate has been revoked. It treats indeterminate

results as failures.

Select Yes if possible to check if the certificate has been

revoked and to reject certificates which have been known

to be revoked but to allow certificates if the result of the

check is indeterminate due to missing revocation

information in the certificate or a failure to check the

revocation status, such as in situations where there is no

response from the OCSP responder, or an inability to

download the CRL, and so on.

Select No to disable certificate checking.

4. From the web interface only, select Save.

5. (Optional) If you are securing SIP connections using TLS certificates, continue with Securing

Connections to the XT Series Using TLS on page 203.
