Feel more confident speaking on the phone than in person?

I dont mean txt I mean actually speaking on the phone, I feel like an extrovert whilst talking on the phone and an introvert in person.

How can help my in person confidence to match phone call confidence?

I use to be nervous to talk on the phone but I did cold calling over 10 years ago that helped overcome my fear.

Should I speak to a therapist or a life coach that could me practise.
