Problemas con el firmware 3.3.1 a 3.3.4 Polycom 330

I have a client with 30 teams Polycom (330) with firmware 3.3.1, we perform a acualizacion to version 3.3.4 to 18 of these teams and were causing me problems, stayed frozen or blocked after a few minutes of having set the connect to the electric current. He had to make a downgrade to not generate this problem. And teams are working perfectly with version 3.3.1
Anyone have a similar problem that can help me. Thanks.

Re: Polycom 330 is getting frozen when we upgrade to the 3.3.4 firmware

Hi Community, let me explain the problem again:


We have an IP Phone 330 when we perform an upgrade from version 3.3.1 to 3.3.4 the phone is getting frozen and don't responds. After that is necessary to do a reset in order to get it working again.


As a solution we perform a downgrade to 3.3.1 version to reestablish the service.


Thanks in advance

Re: Polycom 330 is getting frozen when we upgrade to the 3.3.4 firmware

Hello DSantos,

welcome to the Polycom Community.

This is most likely caused by a configuration issue and you should mainly check your log files for errors first.


Have you always used UCS 3.3.1 or did you previously use anything like SIP 3.2.x ?

If yes to the above, how did you configure the phones? Did you use the cfcUtility to convert old configuration files?


I would suggest you work with your Polycom reseller to troubleshoot your customers issue or let them bring it to the attention of Polycom support.

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

Best Regards
