I've bought a Wharfdale IN 120
It has call waiting as a feature which is essential as my OH is often on call.
There are no details on how to use is in the manual.
After going back & forth with Argos (who provide the "technical support") they reckon that the feature probably means that the phone will beep to notify me there is a call waiting - and thats the limit of the facility???
My last 2 phones had call waiting & I could go from one call to the other & back again.
Anyone any advice on if & how I can use it on this phone?
