Slow Dialer on Trio 8500/8800 ?

Hello all, we recently started testing the trio 8500 and 8800 for use as zoom room controllers. - the zoom portion works very well - what users complained about - and we were able to easily reproduce - was that just doing a regular call via the keypad was very frustrating - if you dial digits as one is used to on a regular keypad, numbers would sometimes not register - it’s very bad on zoom, so,what better but still pretty bad when reverting back to the stock (latest) polycom firmware.


same results on multiple hardware


i have searched around and have not really found anybody who seems to have this problem (or they put up with it?) I even got desperate to the point of looking at booking up a numeric keypad to the USB port! Just wanted to see if this is something anyone has experienced or had advice about.

Hello @BorisT ,


welcome to the Polycom Community.


Can we establish a couple of fatcs before we proceed further ?


Is your Polycom Trio running in:


  • Zoom Mode aka the UI is Zoom i.e. as shown => here <=

    If yes please contact Zoom support directly

  • Is your Trio running a Hybrid configuration aka showing multiple lines as explained in the 2nd part of the above linked post?

    If yes please follow the below.

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.

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

Best Regards

Steffen Baier
