I'm after a free RTP traffic generator to do some QOS testing in a home-lab setup.Would prefer a XP based software.Any suggestions?
For traffic generation Windows is pretty bad, especially UDP at any decent rates. If you are just after simulating one call then you could quite easily use MS Netmeeting between two PC's and make a G.711 call. Obviously you won't get any decent stats out of Netmeeting but I assume you are using this to test QoS policies on routers or switches?
I would recommend the IP SLA feature in IOS to simulate VoIP and the statistics it generates are very good.
Commercially as a company we use NetIQ Vivinet Assessor with Linux endpoints to test 'Network readiness for VoIP'.
