Not an IAX expert, but the last time I looked it always wanted to  
decode dtmf and carry in signalling messages. Perhaps someone more  
knowledgable can clarify. Plus if using other than G711 dtmf will be  
problematic if inband.

This sounds like the phone is using a timer not a digitmap to know  
when you have completed dialing. try hitting the # key when done  
dialing and see if that spees things up. The # is frquently used to  
indicate dialing completion. At least then you will know where to  
look to adjust.
