[Asterisk-Users] Really Old Rotary Phone

[John Novack]

Red and Green are the Tip and Ring. Yellow may have to be strapped to 
one or the other depending on the phone you have.
Some phones may not ring at all, due to special frequency ringers 
installed in them for party lines.
Western Electric did not use these.
As to the ATA, MOST ATA's do not support pulse dial, though the IAXy does.
Asterisk does in the TDM400, though the decoding code  requires some 
modification for dial speed variance.

There are a group of telephone switch collectors that use Asterisk as a 
tandem switch to interconnect old ( very old to you ) switches through 
the Internet, so what you want to do really isn't that strange.
