Phone Not Making Outgoing Calls

I have an LG G6. Often times when I try to make an outgoing call, when I press the call button nothing happens. It happens when I call from the phone app, my texting app, etc. Then sometimes 30 seconds after I've given up and put the phone in my pocket, it will finally call who I was trying to call.
