[cisco-voip] Retrieving device information from CISCO

OK, I've implemented a simple system using SNMP to retrieve the full
phone table and direct connections to IP phones verify that stored data are
still current.
The snmp query on a cluster of 3 nodes takes about 60 seconds
(about 1000 phones).
It works but I really don't like it very much since I still have to get
the full table via snmp.
Retrieving a single phone is only possible if you know the snmp index
of the phone, but since I only have the MAC address, I still need
to search the full table of MAC addresses to retrieve this index (based
on the MAC) and get the IP address with a single query.
Thus, I need an snmpwalk plus an snmpget, at least.
Do I miss something?
A better solution would be via AXL Serviceability, as suggested by Alex Wolf,
but I'm being quite puzzled looking at the documentation and I did not manage
to build a valid query to date (invalid request).
A real sample code for a RisPort query for a single phone will be
very appreciated.
Thansk all for your help.
Andrea.
