# This script searches the did log for a matching phone number and returns 
# the number of matches, it was designed to be used with the ViciDial Inbound 
# DID Filter Phone Group feature in the URL search type with the following URL:
#  VARhttp://server/vicidial/did_recent_call.php?phone=--A--phone_number--B--&did=--A--did_pattern--B--&hours=48
#
# OPTIONS:
# did - you can specify the DID, use the did_pattern or leave blank to search all DIDs
# hours - number of hours you want to search back to find matches or leave blank for no limit
#
# CHANGES
# 131108-0630 - First Build (based on vtiger_phone_match.php)
