Certificate Signing Requests (CSRs)
You can use the basic built-in tool in EMS to generate a CSR that is compatible with Avaya SBC. However, is not mandatory to use this tool to generate a CSR.
Note:
Generate a CSR if the device does not have an ID certificate or if you change any of the device attributes, such as CN or Subject Alt Name.
Do not generate a CSR to renew a certificate that is about to expire. Use existing CSR from the Certificate management page.
