1024 bit certificate for provisioning

We are using an FTPS server to provision VVX phones. The FTPS server is using a 2048 bit cert. Everything works.


We have a need to provision IP 330 phones with FW 3.5, we will have a separate FTPS server for this. The IP 330 only support 1024 bit certs. You cannot get 1024 bit certs anymore unless you self sign.

Is there a generic 1024 bit certificate that Polycom provides that we could install on our FTPS server which IP 330 with FW 3.5 would trust? This way our communications would at least be encrypted...

Re: 1024 bit certificate for provisioning

Hello @SomeoneElse ,

welcome back to the Poly community.

Some or a couple of your old post(s) or reply(s) to them => here <= are still open/pending as you have not marked these as "Accept as a solution" or at least provide some form of feedback or answer.

If they are in this state nobody finding them via a community search will know if an answer or advice provided was useful and has maybe helped you.

Could you therefore kindly go over them and mark or answer as appropriate?

If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilise the community more efficiently. Please do not simply mark them without any type of feedback.


One of them was escalated with our support team but they never received an update from your end.


For your new issue, the firmware version quoted is not a version I recognize. We do trust the attached list of certificates.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
