It's the correct behavior because you're using analog FXO. Call progress 
is only available with digital lines of if you turn on the analog call 
progress detection. Analog CP is very experimental, and for the 1.2 
branch only usable with US tones.

Use ISDN BRI or PRI if you want proper call progress.
