I don't think you can do that, since asterisk has no way to know when 
the shared PSTN line is answered by your analog phones...

I don't think asterisk "counts" the rings, as much as it waits for 
"answered" status, which it is never going to see in your current 
configuration.

I am a relative newb though,  so maybe someone else here has a 
brilliant idea for you?
