[Asterisk-Users] FAX difference IAXModem / Hylafax and spandsp app_rxfax

[James Armstrong]

Found out why there is no original DID set. It looks like while waiting 
for the incoming digits timeout (DID), we are getting the fax tone 
detect and it is sending a digit 'f' which immediately starts the fax 
extension before the incoming DID has been saved.

Is there a way to set in the zap config how many digits we are receiving 
so there is not timeout waiting for the last digit? We only get 7 digits 
coming in.
