[FAQ] Do Polycom phones support a CSR/Certificate Signing Request ?

Polycom phones always have supported a CSR / Certificate Signing Request and traditionally the signature algorithm SHA1 was being used and the requested certificate was 512-bits in length.


UC Software 5.5.0 and later changed this to SHA256 and a 2048 bit key is being used.


To start press Menu > Settings > Advanced > Administration Settings and scroll down and select Generate CSR




  • Fill the CSR info with a meaningful Common name example dot1xPhone
  • All other fields fill in as needed
  • Press the “Generate” softkey to upload the CSR and private key to your provisioning server

The Phone will upload:


  • <MAC>.csr

The CSR File can now be used to open as an example a Windows Certificate server.
