[OFB Cafe] Distinctive Ring Fun

[Timothy Butler]

Hi everyone,
	I'm looking to do some fun tricks with a distinctive ring (e.g. it's  
another number that rings my main phone line, but with a weird  
sounding tone so that it can be distinguished from the primary phone  
line. I've read about switches that automatically route calls to  
different ports based on this. Does anyone have experience with these  
devices? Basically, what I want to do is this: if the call comes in  
with the normal ring, leave it be; if the call comes in with the  
distinctive ring, route it to a port where I can have an answering  
machine intercept it.

	On top of that, if possible, I'd like to have the device detect if  
there is a fax tone when the answering machine picks up, and if so,  
switch it to a third port, which has a fax machine attached to it.

	Potentially, in the future (or maybe now) I wouldn't mind doing all  
this with something like Asterisk, if that is possible (please let me  
know your thoughts on that), but primarily, I'd like to just use a  
little switch box of some sort.

	I think all of this is possible. Suggestions on how to do so?

	Thanks,
		Tim
