Uploading a trusted certificate
An IP phone is authenticated as a client
Generally, the client verifies whether the server is reliable. In some cases, the server verifies
whether the client is reliable, which is determined by the server configurations. When an IP
phone is connected to an HTTPS server, the IP phone sends its client certificate to the server.
The client certificate is uploaded in the
Server Certificates
area on the
Security
tab page.
2.7 Upgrade and Restore
Do not power off an IP phone during the upgrade. Otherwise, writing to the flash memory
fails and the IP phone is down. If the IP phone is down, perform the emergent recovery or
deliver the IP phone to the factory for repairing.
2.7.1 Upgrading an IP Phone Manually
