vvx300 error

Hi everyone,

I tried searching the forums for an answer on this but could not find one.

I am posting about my office phone. It is a VVX 300 and there's a little phone icon with an "x" over it.

I'm not sure what happened here, it was working fine one day and then this happened.

It doesn't receive or place calls, and is pretty much unusable.

For whatever reason, i can't get any work tech support to look at this and it's been a few days and i thought i'd try to troubleshoot but i can't find any info on what to do.

Any and all help is greatly appreciated.

Hello @WHGSB,

welcome to the Polycom Community.

Please also include if you are using a SIP server or a LYNC / Skype for Business server.

If LYNC or Skype please provide Version details and if these are on premise of off premise

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


Most likely your actual issue:

Your work IT Team needs to check this for you.

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