Configuring Network and Session Initiation Protocol (SIP) Features
Certificate Validation
Certificate validation is enabled by default. Validation occurs by checking that the
certificates are well formed and signed by one of the certificates in the trusted
certificate set. It then checks the expiration date on the certificate, and finally,
compares the name in the certificate with the address for which it was connected.
If any of these validation steps fail, the connection is rejected. Certificate
validation is controlled by three parameters which you can configure via the
configuration files, the IP Phone UI, or the Aastra Web UI:
•
https validate certificates
- Enables/disables validation
•
https validate hostname
- Enables/disables the checking of the certificate
commonName against the server name.
•
https validate expires
- Enables/disables the checking of the expiration date
on the certificate.
User Interface
