when i change '.' to '!' then the overlap digits get lost. this means 
the longest number dialled on my telco line is as long as there are 
abigous matches in the dialplan.
isn't there a way to start dialling after one received enough digits to 
decide which path to dial and then still transmit the remaining 
(overlapping) digits?
