Hello ferrel,
welcome to the Polycom Community.
It is always useful to include the currently used SIP or UC Software version as issues experienced or a question asked may already be addressed in a newer release.
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 "Read First"
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
Also the rest of your questions are already answered in the FAQ:
Mar 07, 2013 Question: What does the message "Config file error. Error is <Hex #>" / 0x4020 mean?
Resolution: Please check => here <=
and
Oct 7, 2011 Question: How can I setup my Phone / Provisioning / Download / Upgrade / Update / Downgrade Software?
