If you have faxgetty properly configured to understand the callid, you
should see something like:

        Mar 14 12:35:37 espresso FaxGetty[8744]: STATE CHANGE: RUNNING -> LISTENING
        Mar 14 12:35:37 espresso FaxGetty[8744]: --> [4:RING]
        Mar 14 12:35:37 espresso FaxGetty[8744]: --> [5:CID: ]
        Mar 14 12:35:37 espresso FaxGetty[8744]: --> [9:DAD: 8236]
        Mar 14 12:35:37 espresso FaxGetty[8744]: --> [4:RING]
        Mar 14 12:35:37 espresso FaxGetty[8744]: ANSWER: Call ID 1 "8236"
        Mar 14 12:35:37 espresso FaxGetty[8744]: ANSWER: Call ID 2 ""
        Mar 14 12:35:37 espresso FaxGetty[8744]: STATE CHANGE: LISTENING -> ANSWERING

If you don't see the 'ANSWER: Call ID ....' lines, then you have to
configure faxgetty to use them.  On my device, it's:
        CallIDPattern:         "DAD: "
        CallIDPattern:         "CID: "
so the DAD: match is assigned the 1st CallID and CID: match is assigned to
the 2nd CallID.  But it will be different for different devices.  The
man page will help you figure out what they need to be for *your*
modem.

In this case, my faxgetty is configured.  So in  my FaxDispatch, I just
use $CALLID1 and $CALLID2 to refer to them.

case "$CALLID1" in
        123) SENDTO="joe@example.com";;
        234) SENDTO="jack@example.com";;
        *)   SENDTO="catchall@example.com";;
