I think I have been shocked like that from phones before.  If you have
a carpetted environment, where the persons electrical potential can
float relative to the phone's ground, you are going to have a build up
of potentially high voltage.  When you put the phone up to your ear,
the distance to the skin of metal is going to be smallest, and that's
where the breakdown occurs, to a nice sensitive area like the ear.
Would probably be solved with anti-static spray on the carpet, or more
grounded conductive surfaces in their environment to discharge
themselves on.  Maybe a conductive grip to the handset with a spark
dissipating resistor.
