Looking at the code in chan_zap.c, I only see options for feature group B and 
feature group D MF. The 2 stage MF signalling you are asking for isn't 
implmented in the latest asterisk source code. 

I would suggest you post a feature request detailing your 2 stage dialing 
requirement to bugs.digium.com as 911 support is something which could be 
useful to others.
