welcome to the Polycom Community.
If this is a question on how to reset the Voice Mail password then we, the Polycom team, will not be able to help you as the voicemail system is provided by whoever you have your telephone service with.
If the question is how to reset the phone Admin Password please check below.
We do not disclose within this official Polycom community how to reset the Phones if the Admin Password is lost.
Many of our partners utilize these phones and offer services so we cannot publicly disclose the procedure to do so.
If your phone is still able to connect to the Provisioning server please reset the password via the Device Parameters documented in the Admin Guide or here
The above is also stated in the Read First: Welcome to the Polycom VoIP Forum
If this is not possible please contact your Polycom reseller or the person you purchased the phone from.
We will remove any post replying to this that will publicly explain how to remove the password.
