Dealers are still able to update firmware on these nice phones and beoline 2 bases that fixes many issues on older firmware versions. does anyone have the release note telling the difference between firmware 2.4 and 2.43 on the base and phones? B&O are telling me These are the latest firmware software for your:Beocom 5 is Software 2.43. Beocom 2 is Software 1.2. Beoline 2 is Software 2.43. We do support the dealers to update the Software version of your Beocom 5, Beocom 2 and Beoline 2 if they still have a cable.
