A listener-supported radio broadcast station has a telecom problem. Their local (212) pledge call-in number (for on-air fund drives) was just outsourced to an outfit in nearby (516), but they'd like to continue using their well-known (212) pledge call-in number if feasible.
What free or low-cost options exist for forwarding thousands of listener calls without incurring per-call charges, or for inexpensively porting the (212) number to the nearby (516) location?
Thanks for all your replies. Because this (212) number will be used for on-air fundraising, any solution will require up to ten (10) simultaneous calls to be forwarded to the (516) number's call center.
