I'm looking for a switch that shuttles between one or more lines based
on distinctive ringing patterns. Ideally the switch would send a
normal ring pattern down the leg selected, thus saving me the expense
of shunts/modems/faxes/answering machines that also detect DR.

The point of all this is to have my otherwise idle home phone appear
as a business phone, and to hopefully allow me to wire up a
voicemail/fax system at home.

Personal 800 number is forwarded to special ring number.

   "Please dial the extension of the party
   blah blah blah blah"
 
  Ext 1 = My voice mail
  Ext 2 = Roland's voice mail
  ...
  Ext 11 = Take a # via tone detection
           and page me with the #
  Ext 12 = Take a # and page Roland with it
  ...
  Ext 42 = Ring Cordless phone on line 2
  (known to few but keeps home # totally private.) 
  Ext 911 = Take message, ring me on cellphone and playback.
                                            
Any improvements, brandnames, or suggestions, are welcome.  John
Higdon 15 lines at home on a 64x16 PBX in your basement smart alecs
need not apply :-) ... (but anything else you might have to say would
be great, Mr. Higdon.)

Also, if this system could be setup so that answer during the day with
a secretary and multiple lines could easily be added later, that would
be even better. In fact, it may be that a very small PBX would scale
better?
