This would be somewhat useful.  When there is stutter for whatever 
reason, outbound dialing must be delayed a couple seconds.  Some times 
my PSTN line would roll-over to the telco voicemail before * would 
answer, someone would leave a message, then outbound dialing would fail 
until the PSTN voicemail was cleared.  (Now my * answers on first ring 
so this isn't a problem anymore.)

Would this have to be done in the Zaptel hardware driver, the chan_zap 
code, or somewhere in the mainline code?  I've seen the tone detection 
routines in dsp.c, could these be brought to bear?  (Answer in -dev if 
this gets off -user subject too much.)
