We need to do load tests for a IPCC deployment. Does anyone know a simulator tool to use to generate VoIP calls and test load of the IPCC and IVR (200 concurrent calls on the IVR, thousand calls in an hour).

I am having a minor problem with the scripting of the IVR. I am using GET DIGIT STRING to get the DTMF data entered. The clients claims that the Australian STD requires 10 secs for Initial Time out, but the script editor only allows me up to 8. Anyon...
