[cisco-voip] VoIP qualification and monitoring

[Eric Helm]

I've been looking at some products for 'pre-qualifying' customer 
networks for QOS/VoIP and for analyzing and monitoring our VoIP 
infrastructure.
Protocols used are SIP, MGCP and SCCP.
Codecs used are g.711 and g.729a.

Some of the vendors for VoIP monitoring and analysis that have come up 
include Acterna, Artiza, Clear Sight, Empirix, Finisar, Fluke, Network 
Associates, Radcom, Voila and Wildpackets.

Some of these vendors and Ixia have come up for QOS and VoIP qualification.

Anyone have any recommendations/experience with any of the above 
product(s) or other suggestions for my requirements?
