[Asterisk-Users] delay on pri dialling when asterisk is spliced between E1-Pri and legacy pbx

[Adam Dobrin]

You aren't dealing with analog phones, and you aren't transmitting DTMF 
signals.. the functional difference between analog and digital systems 
kindof precludes what you are looking to do.. meanwhile, once the entire 
number has been dialed, the outgoing call should be started almost 
instantaneously..

maybe set the initial context so that the longest dial string is the 
length of the extension..?
