I recently had my Electronics vendor install a Front Door intercom which is integrated with our hardline phone. The Intercom causes a distinctive ring so that I can answer the door with my phone. My question is whether there is some audible sound/tone if I happen to be talking on the phone when the intercom button is pushed?

If you are already on the phone when the doorbell button is pressed you will hear a call waiting tone. Simply press “**” to put your call on hold while you are connected to the door speaker. Press “ **” to return to your call.
