Unable to hear incoming calls since my headphone is connected and not on my ear

Hi,

Wondering if anyone could help me. I only put on my headphones when on a call. Once the call is done i take of the headphones and place them on my tablewhile they remain connected to the laptop. Due to that when I get an incoming call I don't hear it from the laptop speaker since the headphone is connected. Hence a lot of times the calls gets missed even though I was connected and available. 

Is there a way I could also get to hear the incoming call from the laptop speaker as well even though the headphones are connected? I know I could just plug out the headphone wire after every call but wanted to see if there was another way? 

Any help would be appreciated.
