Do Accounts Receivable Require Lots of Phones?

I've done AR/AP and Bookkeeping for the past decade. I just accepted the job from a hospital called "Accounts Receivable Follow Up Specialist." Ive done AR and never had to be on the phone at all. I absolutely hate customer service roles (phones, live chat, etc.) I just work on invoices, excel, and quickbooks. Im doing training and all I see the person im shadowing just do calls after calls to insurance companies to collecg payments and dispute denials. Im pissed becaused i told the recruiter I wanted a non phone role. Its why ived done nothing but accounting. Is is common to be on the phone a lot in medical billing?
