Linux Editing phone number with multiple delimiters

Hello all
I have a data base of information that is formatted like so:
JSD4863 XXX-XX-XXXX DOE, JOHN C JR-II BISS CPSC BS INFO TECH 412/779-9445

I need the last four digits of the phone number. However, many lines contain
'garbage data' that I'm not interested in. So i used a 'for loop' to specify
which lines i wanted. The code looks like this:
Code:
#!/bin/bash
for linePosition in {11..22}
        do
                holder=`sed -n "${linePosition}p" $1|awk '{print $12}'` 
                echo "$holder"
        done

This gives me the 11 lines that I want. However, it gives me the full phone
number. I want to ALSO pipe this command to only give me the last 4 digits.
I am not sure how to do this since the fields are delimited by two different
characters. I tried a couple variations of cut, but nothing work.
Please help

NAME
phones - remote host phone number database SYNOPSIS
/etc/phones DESCRIPTION
The file /etc/phones contains the system-wide private phone numbers for the tip(1) program. /etc/phones is normally unreadable, and so may contain privileged information. The format of /etc/phones is a series of lines of the form: <system-name>[ ]*<phone-number>. The system name is one of those defined in the remote(4) file and the phone number is constructed from [0123456789-=*%]. The `=' and `*' characters are indicators to the auto call units to pause and wait for a second dial tone (when going through an exchange). The `=' is required by the DF02-AC and the `*' is required by the BIZCOMP 1030. Comment lines are lines containing a `#' sign in the first column of the line. Only one phone number per line is permitted. However, if more than one line in the file contains the same system name tip(1) will attempt to dial each one in turn, until it establishes a connection.
