Before we get stuck in just a note about the functionality. If you are looking for a device that can integrate with your desktop Lync client then this is NOT the device!
This phone is for those “dial tone only” locations like in the lunch room.
When thePolycom IP331 arrives it usually has an older version of software on the device. Mine came with SIP Software version 3.3.3.x and Boot ROM Version 4.3.1.x
OK, so the phone needs the UC SIP Software Version 4.0.x to play nice with Lync. Shouldn’t be too much trouble, yeah right!
After spending hours chasing my tail on the net I finally managed to upgrade the phone. So here’s the quick facts.
Before the Upgrade the phone URL access was user Polycom, Password 456 and disploayed the image below once logged in.
So we begin, first you will need to have an FTP server up and running. I used Filezilla Server.
Once installed you will see the Connect to Server window, just click OK
Next we need to define the user and home directory. Click on Add user and define the user name
Next, define the FTP root directory.
Make sure you allow Write and Delete, and set as home
The FTP server is now configured, next you will need to download the Upgrade files for both the BootROM and the SIP Software. Its a bit overwhelmed when you get to Polycom’s website since there are so many different phones and software versions.You will need to go to the site to download the correct files.
I will document the IP331 files.You are presented with a Combination and a split download. Regardless of the BootROM version (and contrary to what the site states) download the combination.
When you click on the link you are presented with the page below
Had to change off DHCP so as not to get settings for internal IP PABX. After download and reboot remember to switch back to DHCP so Lync FE can be resolved.
