Don Coyote,
"
From the instruction manual to my Panasonic KX-TG8423 phone:
2 handsets in the same radio cell can have a conference call with an outside party."
Thanks! The misery here started because the two handsets (Siemens, now rather ancient) in the same radio cell were NOT capable of a conference call. No mention in the manual, and a phone call to Siemens confirmed the feature didn't exist.
This seems to have been 'cured' now, as you confirm, and as my check with Philips support also confirms.
daved123,
Looks as if your setup is much like mine, one DECT on one socket, and cheap handsets and suchlike on the other sockets. I already know that works...
I'll now just have to make sure that whatever I get to replace the now totally clapped-out Siemens 'dual'
does have the 'conference call' feature - my problem simply was that I was not aware yet that it existed on a typical present-day 'dual'.
Many thanks to everybody for helping out to sort this!

PS The Siemens was a "Gigaset 3000 Classic".
Pretty cruddy... within a few years the memory feature (stored numbers and the 'redial') gave out completely, one of the battery sets (standard AA rechargeable, luckily) failed, and today the chicklet keys have to be wiggled or pounded to work at all...
Which explains why we're looking for an update...
