I did away with my pager 3 yrs ago, and just use my phone (Razr at first, iPhone past 2 yrs). My answering service just calls me direct. Patients and hospital staff are quite surprised at how quickly their calls are answered. All the hospital units were given my phone number to call preferentially, my service secondary. This works well since I share call with a few physicians, so call is spread out. There was some busy work involved, but, there aren't that many different extension numbers on the hospital units that 95% of my patients are on. Just named them and put them in the address book. If you can't pick up the phone right away, visual voice mail then is more informative. One advantage to using an iPhone vs a pager.... there are radio dead spots in the depths of the hospital (radiology, elevators). Pagers miss the call, your phone picks up the missed call notification and voice mail notification as it reconnects to the wireless. As an aside, told all the consultants I use to call my cell preferentially after office hours... much speedier and personal service.
