I haven't gotten my hands on a UC500 system yet, so I can't answer this question by trying it.
Is there a way to assign multple features to the same soft key? You would "page" over to change feature assignments. This way you can get around a physical soft key limitation.
I'm trying to spec out a phone for a system and my concern is being able to monitor extension status (BLF) but monitor more extensions than the number of physical soft keys.
Thanks.
