I use a traditional answering service and an iPhone. Haven't used a pager in over 12 yrs. The added cost ($40/mon) for the answering service is a small price to pay for the convenience of screening out some of the dumb calls and the service insures that if a call is missed (rare) another request gets sent out.
As an aside, I once joined a group (before cellphones) that just gave patients their home phone numbers... Don't-EVER-Do-That!
