At least, not in the analog TDM world. Personally, I'll advise everyone 
to use ISDN if you need to detect call progress for TDM circuits. Or if 
you're in North America, try the callprogress=yes option in zapata.conf.

Analog lines are perfectly fine is you're happy with call progress 
detection in Wetware(TM) :). For automated call progress detection, you 
would be happier with a digital line or VOIP.
