Ensuring adequate voice quality is critical to maintaining subscriber/user satisfaction. Continuous monitoring, measuring, and troubleshooting are all required functions here.

Having good QOS and adequate network segmentation are the 2 biggest factors. QOS has to be conistent across your entire network.

As for measuring performance, I have seen some 3rd party apps out there such as NetQOS that supposedly do this. I am not sure how well they work, but they look promising in demos.

Generally if you are having issues with congestion, etc. having VOIP will bring them to light as VOIP is more sensitive than data traffic.

Hi,

Apart of QoS, that it would help you to predict any situation in the network, and as complementary. The use of polling SNMP servers can help you to see if there is any congestion. One nice application with easy implementation is cacti server (http://www.cacti.net/). It's a free software solution and fully customizable, doesn't require a lot of hardware (you can run in old computers) and you can store data in external database.
