audio conference calls

I always heard some of my mom's friend were complaining about how expensive they're monthly phone bills because of the long distance the make to communicate their family back home. They were asking us what phone company we were using every time we communicate our family back in the Philippines. What they don't know is we are using audio conference calls. It is a No Monthly Charges - No Contracts.. It's really a great way to communicate our family and love ones back home with out rushing and worrying about getting a huge bill every month.Thank God for this audio conference calls if not because of it we were not be able to keep in update with our love ones.
