AW: [cisco-voip] Retrieving device information from CISCO

I'm using AXL Serviceability API to query IP Addresses of phones.
It offers various criterias to query (like devicename, only registered phones etc.)
See http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guide09186a00802e3df8.html <http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guide09186a00802e3df8.html>
The only disadvantage is, that you have to poll the device states (the poll rate is a service parameter) With (J)TAPI you get events on device changes, so truly asynchronous behavior can only be achieved using
Regards,
Alex

Cisco will be removing devicelistx.asp in the near future. SNMP and AXL will be the only method of retrieving device information.

"devicelistx.asp has a finite future" - Would you care to elaborate on that point? We have many inhouse applications that rely on devicelistx.asp, so if it were to go away these would have to be reprogrammed.

As this is such a frequently asked question and devicelistx.asp has a
finite future, I will test as soon as I get a few minutes. My
initial sources say:
SNMP MIB
ccmPhoneInetAddress - .1.3.6.1.4.1.9.9.156.1.2.1.1.15
ccmPhoneInetAddressType - .1.3.6.1.4.1.9.9.156.1.2.1.1.14
AXL
request string - listPhoneByName
parameter - searchstring %

For real-time reg info, dlx is the only way.
You could also use JTAPI to monitor the device, but that's obviously
pretty heavy, depending on how many phones we are talking about.

Thanks all for the useful hints.
This saved us a lot of time.
I just have a last question.
I've reviewed the sample application in the SDK,
and it uses DeviceListX.asp.
i.e. to retrieve the IP address of a phone, it gets the complete list,
loads it in a vector, then searches the phone name to extract the IP
address.
This looks to be the only way to do this.
Unfortunately this way can be quite heavvy if you need
to query the resident http server of hundreds, or even thousands of
IP Phones independently from each other.
However we can "optimize" getting the list once per a time interval,
but is still an overhead and prevent us from working asynchronously,
I mean we will need to build a synchronous application that will batch
al operations at fixed time intervals, then get the current list at that
time, perform all batched operations, and the sleeps for next time
interval.
Not very nice IMHO, but looks to be the only way out.
I would have expected a smarter API, something like
GetIPPhoneRegInfoByName,
using the SEP name to retrieve registration info of the phone from
the callmanager.
This would be a natural complement of the DeviceListX.asp report.
Is there any way, perhaps undocumented, to obtain regstration info
for a single IP phone at a time, or are we bound to retrieving the
complete list?
Thanks in advance for your comments.
