Yes, it got resolved, the following firmware will fix it:

My method would be as follows.
Check your current Firmware/Software, if it begins with 072, do the update yourself.
If it begins with 071, I suggest having a tech wipe the device with what is called a "Forced altboot, no data backup no clone"
This would entirely wipe the device though, every setting would need to be redone on it manually, the reason being that the 071 (Connectkey 1.0) to 072(Connectkey 1.5) involves some serious upgrading and changes. the address books, the fax system, the accounting and print engines are all very different on the backend, and may not play nicely in an upgrade.
Think of it like WindowsXP and going to Windows 7, or Android4.2 and just updating to 4.4, while it can be done and may work fine, you are better safe than sorry.
