[cisco-voip] IP Phone voip Network statistics

[Stephen Welsh]

Jeff,

As mentioned you can pull the stats from the phone's web server directly, this is real-time data, it's actually the raw data that is submitted back up to UCM to record in the CMR at the end of the call. You can poll this from the phone on a regular/timed basis and get mid-call stats, but keep in mind the phone's web server is not the most robust, too many requests and it can lock-up, possibly requiring a restart of the phone to get it back into life, so pacing the requests is important. You can pull the Call Statistics after a call has ended too, you will get the final stats for the last call on the phone.

I recommend you download PhoneView from Unified FX (http://www.unifiedfx.com), among many features it can pull call statistics from multiple phones at once, if you select one or more phones you can perform a "Call Statistics" query on all of them at once pulling the current/last call details (MOS and Codec). This information can be exported to a file for comparison later.

Note: The phones themselves are pretty basic, the most advanced interface they provide is the in-build web server, if what you are looking for is not there you will have to look elsewhere (i.e. UCM) but generally there is minimal individual phone details available from UCM, if you have a look at the serviceability API there are some phone details available via the RISPort API.

Note: There are no MOS statistics for the first 8 seconds of the call, the algorithm needs some data to work with before it can provide the relevant MOS score.

Thanks

Stephen

Looks like the stats are there on the phone's internal webpage, if you really absolutely needed to poll the phones you could write a program to scrape the stats out of the HTML and turn around and feed it into MRTG for graphing or something.. it would be kinda ugly though.

I'm not sure if those stats are updated real-time or not.

Hi,

Cisco Phones are able to display jitter, delay, MOS and stuff.
Is there a way for it to be polled by SNMP servers like
solarwinds/mrtg for display and alert status?

I believe most part of snmp are on CCM. How about for cisco phones?

Thanks,
Jeff
