Disable Mute Button on SoundPoint IP 331 and 335

Re: Disable Mute Button on SoundPoint IP 331 and 335

Hello hbrambila,

The Admin Guide states:


  • Note that IP_330 parameters affect SoundPoint IP 32x/33x phones

The above includes SPIP331.


Therefore the parameter should be:


key.IP_330.24.function.prim="Null" key.IP_330.23.function.prim="Null"

If the above does not work and your customer refuses to upgrade to a currently supported version I can only ask you to either try and get help here or open a PPI / Pay per incident ticket with your Polycom reseller if the phone is out of warranty.

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

Best Regards

Steffen Baier

I didn't understand that the parameters "IP_330" would works for all models 32x/33x. I didn't pay attention!


Thank you very much for your support and attention. Congratulations by your commitment and dedication.
