which I installed however when I go into the Management Console for that phone, the firmware shows as unsupported and wants to install 2.12.16.20 which I tried however causes issues with the Fanvil EHS. Why is the console not accepting the firmware listed as being the proper version, what am I missing?
If you are using V18 please note that your server will not recognize any firmware newer that what it says.
Also note that on our firmware page mentioned above, we have a note posted:
At this stage since you are already running newer firmware, it's probably not a good idea to try and downgrade the phone as it could lead to issues, or the phone may reject the downgrade altogether.
When you upgrade your PBX to V20 the message should go away.
