In case anyone else is wondering, the answer is that the BeoCom 5 is software updatable. Took both handsets to my dealer today who noticed they were at 2.1 (Nov 2010) and updated them to the most recent 2.3 software. No idea what this does or offers nor whether it fixes the above problem (yet).
Actually, the update does not do anything for you from 2.2 to 2.3 because its just a software change to ensure that the units are backward compatible after a new hardware component was introduced into production.
Only one problem was fixed from veraion 2.1 to 2.2 and that is if you are in a call and you place the phone on the speaker it ends the phone call.
From version 2.0 to 2.1 the following issues were resolved:-
- tHE Handset loses contact with THE base -- "Base not found"
- No dial tone on line 2 after incoming call. US VERSION ONLY
- No caller-ID, no missed call, no caller-ID in list
- With Swedish base language, the duration of the call no longer fits in the screen area
