another work around would be to hit the voice command button and tell it "dial" and then read the number in the appointment.

i've searched many of the windows moble team blogs and they are aware of this problem. this feature is only missing from windows mobile 6.1 professional devices(with touchscreen and stylus), smartphone devices(no touchscreen and stylus) can call numbers embedded un appointments. hopefully we'll see it fixed in the next update.
