[Asterisk-Users] Callprogress and TDM400 in Brasil

[Ricardo Poppi]

Hi list! I´m trying to put to work the "callprogress=yes" for outgoing 
calls using the FXO port of my TDM400 digium board.

The main reason to try that is that I DON´T WANT the asterisk to start 
billing my calls before the PSTN called party answers the line. With the 
callprogress disabled, asterisk detects an answer imediately after the 
line starts ringing and before the other party have answered the line.

So, using the callprogress with the "progzone=br" I get the following 
problem (CLI point of view):

1) Asterisk executes the Dial comand and detects that the other party is 
ringing:

   -- Dial(Zap/g1/XXXXXXXXX|30|r)
   -- Zap/2-1 is ringing
   -- Zap/2-1 is ringing
   -- Zap/2-1 is ringing
   -- Zap/2-1 is ringing
   -- Zap/2-1 is ringing      

2) But, when the other part answers, it detects the "hello" as a ringing 
too!!. And everything said by the called party is detected as a ring!!!

3) Just if the other party gives a great shout: "AAAAAAAA" then finaly 
callprogress detects this as an answer:

-- Zap/2-1 answered 
SIP/XXXXXXXX-7df7                                                                                   




Do anybody has worked with callprogress before? Any clue about witch 
parameter inside zonedata.c I could change to correct this detection?

There is any other way to make asterisk bill outgoing zapata calls not 
from the time it starts calling but from the time the other party answers?

Rgs, Ricardo Poppi.
