I am investigating options for doing recorded telephone message calls to batches of users (about 400 max) for a client.
Ideally a vendor or technology with little or no startup cost, and a reasonable per-use fee - the calls would be used by a emergency management department only to announce updates to town residents in case of emergency, so we could go years without using it, and would rather pay a bit more for each call when we use it then pay monthly for a system that will likely not get that much use.
Suggestions?
