[Serusers] SIp auto dialer

[Iqbal]

Hi

Does anyone have any recommendations, linux one is better, and would 
sipsak do this.
All I want is a number to be dialled, and then handup once answered, no 
voice required.

This is not for spam, just to allow me to dial up random numbers 
worldwide, from which I want to plot a time to completion graph, from 
where I can then hopfully automatically change my GW in lcr, for best route.
