Polycom phone cannot make calls

Dear Experts,


Thank you for reading this thread. My polycom phone cannot make phone calls for unknown reason. The polycom phones used by my co-workers all work fine except mine.


When I make a call, an auto voice is heard, "We are sorry, but you need restart your phone. Unplug the phone and plug back in, wait for 30 seconds before you make a call.", however, I did it several times but still cannot make a call.


In the screenshot attachment "polycom front", it seems I only have DND as an option while other functioning phones have more options, such as New Call, Intercom and Page.


Is there a way to completely reset the phone? What is the problem here?

Hello @Kalimoor ,


welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.

As a reminder the basic information asked for:


  • Provide the exact Software Version of your Phone
  • Provide the Phone Model
  • Provide the Call Platform (aka openSIP,Skype for Business Online, Skype for Business on Premise, Lync)
  • Additional Polycom Infrastructure (RPRM,PDMS or BToE)
  • If applicable provide a backup of the phone in question

UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.
Since UC Software 5.9.0 simply provide this via the Web Interface Diagnostics > Download Support Information Package

  • If possible provide a Log and either attach them or use the Code Tag.Consult the Troubleshooting Section found within the FAQ if applicable
  • If possible provide the MAC Address or Serial of the device
  • Provide details for example if the issue is a day 1 issue or only happened after an upgrade or any other relevant details
  • For questions around Support please check here


Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used. In addition providing all details at the same time allow us to check logs or look up a potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.


Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up post’s.


Looking up the records for the Phones MAC 0004F27915CE shows this phone to be a Ring Central account.


Not sure if this is still the case as it was sold in 28/05/2015 via ScanSource Communications (USA).


I suggest you check with your Admin Team or give Ring Central a call.

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