New Revision: 99076

URL: http://svn.digium.com/view/asterisk?view=rev&rev=99076
Log:
Another checkpoint; rebuild the find_callno routine to use the hash tables; still need to verify I have all the spots where the values are twiddled. Maybe I should store the callno's instead of the pvt pointers in the hashes, as I have to back-convert them.
