The problem is that they are on a PC board not a hand wired board

I just called BG Micro who used to carry these according to a few sources I 
checked.  They are fresh out and the chip is no longer made.

Doing some reading, I found that the Mitel 8870 might do the trick, but it's 
not pin compatible, so you'll have to modify the circuit to use the correct 
pins.  I believe the Mitel might cover all the functions of the SSI-202 though 
I'll have to look at the data sheets for both.

  We are looking for about 5 of the SSI-202 DTMF chips that are in use in our 
RC200 controller boards.  If you have some or know of a source for 5 to 10 or 
these little jewls please let me know ASAP as we will have to build several of 
these boards to accomplish our goals with the VOIP. 
Both Gary and I have looked on the WEB for them and they are available but you 
have to buy a large quantity which we do not need.  Should you know of someone 
selling these chips please let me know.
