How does it work ?
What is a telephone intercom ?
A telephone intercom is an intercom installed at building entrance, which can be used to call residents directly on their phones (landline, mobile).
Extremely simple to use
I receive a call
A visitor contacts me with the intercom. My mobile or landline telephone rings.
I see * and I answer
I pick up my mobile or landline telephone, whether I am at home or outside
I open the door
I open the door of the building by pressing a button (the "*" button, for example) on my mobile or landline phone.
