Back in my home country, they have this what they call "pay phone" wherein people can just come to the store and make calls. Of the three-minute call they make, there is a fix rate for that of five pesos. That makes such a good business in the country for most homes there do not have phone services. I wonder if that small business phone system here would also work there or if there is a service in my home country similar to that of small business phone system here offer the same benefits that an owner could get? This is what you get if you have the service; saves you 50% and invest more in your business, simple easy to use and try with no contracts, sound- fortune 500 business phone experience for your customers, productivity- work from anywhere and save time.
