VOIP - Voice quality measurement

Hi all,

Is there any tools/commands available for Cisco 2621XM (2600 series), with which we can measure the voice quality of VOIP and TDM calls. Is it possible to get some statistical information about the voice call.

What are the metrics used by Cisco for measuring Voice Quality?

Any links, answers and suggestions would be helpful.

Thanks

Re: VOIP - Voice quality measurement

IP SLA is a feature built in to IOS and collects voice quality statistics. See the links below. There are also many 3rd party applications which will allow you to compile and analyze these statistics. Several of these are listed at the bottom of the first link below. The main metrics used to measure voice quality are latency, jitter, and packet loss in the network. IP SLA can also measure the MOS (Mean Opinion Score) which is a standard used across TDM and IP voice networks.
