There are some video producers that advertise a "Tickle Line" that you can call. One that comes to mind is ANA. You can find them here in the Links section. But that may not be what you are looking for, as the call is most likely taped and the duration a couple minutes at best. The idea is intriguing and I'm sure if a company did offer that service and promoted it here on the TMF, they would probally do well.
Solefully Yours, a company sadly no longer with us, used to offer a line you could call to listen to audio of their video tapes. You might find something advertised in your local alternative newspapers in your area.
