Hello,

Currently on release ip office release 9.1 and need to add power user licenses. The only way we can do that is if we upgrade to R11. The current phones are 5621sw's, I know they aren't supported in the R11 release, but will they still work. The mission critical phones would be replaced. We're just trying to figure out if we need to replace all of the phones or if they will still work before we do the upgrade. Any info is appreciated.

Thanks in advance!
 
A 5610SW seems to work OK here and they aren't supported.
 
As stated by ipohead, 5610SW came up working fine on R11.0.4.1, no issues that I've seen.
 
It's been pretty random, got issues with some 56xx phones on a later release so ended up replacing those but others are still running their 5610s.

Problem is if you get an issue later will there be a budget for replacing them or will the customer think you should cover the cost since they didn't know about it.

The issues I have seen.
Button mapping on the 56xx series phones disappear or doesn't work.
Phone just have an a, b, c button to make/take calls.
Call log - time is wrong
Phone "locks up" or is frozen - needs a reboot
