Phone Machine Greeting

Does anyone use a machine that gives a greeting when you call?
I have been looking at one, since not everyone is consistent with upsells.
The one I have been looking at is $100/month. Seems like a lot but if it does work, it should pay for itself.
I am looking for any pros or cons from actual users, who have used or is currently using this product.
Thanks,
Bubba

My pos system comes with that stuff. A customer calls, rings twice, the machine picks up, tells the special of the day, and keeps them on hold until you pick up. its a great way to boost ticket averages. My sales rose roughly $800 a week once i got the pos system.

I used to have a call sequencer before this which kinda did the same thing. it was made by viking… heres something i found.
