I'm having a massive problem with the buttons on a 4425 handset.
The programmed buttons for Call Pickup and Message Waiting do not appear to be working.
How do they communicate with the ESU (TSE ver 3.2 sp2)? Which ports do they use?
I am struggling here and have an increasingly disappointed customer.
Any help greatly appreciated.
