It can fail for one of three reasons on an X100P card:
    1. The caller blocked their caller ID
    2. Your gains are not set correctly in zapata.conf (I believe the
one for caller id is rxgain).
    3. You're using an X100P card...the caller ID hardware on it has
always had problems, and some X100P/X101P cards are worse than others.

Try adjusting your gains, or replacing the card.
