I know the 6408 and 6416 digital phones aren't supported in R9
Will they work in a R9 IP office system ?
Custome want to upgrade from R3.2 to R9 but want to keep these digital sets.
They will work but not supported if there is a problem with it. I already found couple issues with it. Mainly if you add a button module to the phone, the lights will not work (PoE brick did not help) BUT the buttons still work.
We just pulled out and bought a customer 60 newer phones because we took this risk… I would not. There are two concerns:
1. Power
2. Timing
It does not take much to test phones and Avaya is known to try and keep legacy phones in play, so I think there is a reason they were removed from support. Keep in mind 7.0 is the latest supported release.
