Broken Certificate

[CAVoIPGirl]

We are having issues with the certificates that are installed - namely T21P-E2s and a few T21Ps. When trying to access a device outside the LAN remotely, the firewall is blocking our access to view the phone's GUI.

The error message states it's using a broken signature algorithm and the customer's firewall will not allow traffic to pass due to this.

I need suggestions on a fix (the certificate is not expired) because we have thousands of devices depending on resolution.

Current firmware is 52.84.0.140


Thank you.

Hi,

I like to suggest resetting the phone to factory default, re-provisioning and try again?

Hope this will help.
