Here is what I would do.  Install a TDM04 card with a couple fxos.  
Connect the analog phones that your wife will be using to the tdm card.  
In zapata.conf, set those phones to immediate=yes, and when you get an 
event on the fxo port, connect it to the fxs port with the stutter 
tone.  This way, when she picks up the phone, it will immediately 
connect her to the sbc provided dial tone, and she can hear the stutter 
or lack thereof.  When a call comes inbout however, you can still route 
it as you want.

Not a perfect solution, since the phones she will be using are forced to 
use SBC, but the best solution I can think of.
