Could a cordless phone that has an extra handset that uses one phone jack interfere with the other phone?

The Cialis Without Prescription main phone uses a phone jack while the extra handset just plugs into the wall outlet. Not sure if the main phone could work without the extra handset that came with it.

it will work without it…and mine dont interfere with each other if one is on the other will not work and will say unavalible
yes they can interfere
If it is built for it, no, but cordless phones can interfere with TV, Wi-fi, radio, ect…
the main phone that is plugged into the phone jack will work without the extra handset plugged in – the extra handset will only work if the main phone is connected as it needs the antenna connection.
If they have the option of using different channels then try changing the channels on both the handsets – sometimes your channels may get interference from a neighbours handset channels.
