I've noticed a small problem with the BeoCom 5 where it occasionally hangs up on the caller when I put the phone down on the speakerphone base (after answering and when I want to put the caller on speaker). It doesn't happen every time, but happens fairly frequently. Worse, put the phone on the base and I start talking and realise the other person isn't on the line. Not good for handling a business call.
I'm assuming that this should have been fixed in a software update.
How does one go about updating the software in a BeoCom 5? Is it possible to do it ourselves or do we need to get an engineer in to handle this?
