This short video gives you a brief and not too techy overview of what you need to know.

Please note that all prices are excluding VAT unless otherwise stated. Basic assumptions were made to measure savings realistically: average call length 10 minutes to calculate call setup fees / customers are on a "without a call plan all contracts" / call calculations consider peak traffic between 7am-7pm Mon-Fri.
The calculator factors in typical landline setup charges.
