I got a call from this number today as well and there was no message left. My particular number has been getting a lot of telemarketing calls and from these comments it looks like it is yet another one. If you call the number back it gives you a option to add your number to their do not call list which is exactly what I am doing.
Call stated that at "no cost" they would install a security system if I allowed them to put a sign in my yard. It did offer a do not call option. Upon pressing 9 to be placed on their "do not call" list, there was a tone, then it hung up.
