Sales Toolkit?

Hi All

Is there anything you use when you want to demonstrate the cost savings of asterisk?

Is there any particular system you show them a comparison against? i.e. this system is TCO £20k, this equivalent asterisk system TCO is £2k… sort of thing?

Any tips on how I can demonstrate cost savings in support, licenses? Is there a sales toolkit or something I can download?

Thanks All!
