[cisco-voip] Retrieving device information from CISCO

[Andrea Cerioli]

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.
