I am on the BT Unlimited Anytime Plan, and after one hour I have to redial 
to avoid call charges. Are there any DECT cordless phones which have the 
option of producing an audible warning (like Call Waiting beeps) in the 
earpiece after 55 minutes? I like the BT Diverse range of phones but I'm 
guessing these ones are unlikely to have this facility! Thanks for any help.
