they never leave a message.

I got the exact same thing you did. First call there was no one there when I answered, the second time they said they are from VCR.  It says "Out of Area" on my caller ID but I am in the 719 area code?

First time calling, but no one responded after my greeting, but stayed on the line for about 40 seconds.

Interestingly, it said "out of area" on my caller ID, but had the local 719 area code phone no.  Don't think I've ever seen that before.
