Title: Mitel 5610 "incompatible handset version"
Post by: Jcary on December 04, 2017, 04:49:15 PM

I got a few Mitel 5610 phones and got some of them programmed to the dect stand no problem, but a few of them give me the "incompatible handset version" error and won't register. Does anyone know of a fix for this?
