asterisk users - Nov 2004 - AU PSTN Tone / Progress Detection

Hi,

Just wondering whether or not anyone in Australia has been able to get 
/ create an accurate (or semi-accurate) tone detection system. I need 
to know when calls don't connect because the line is busy or they ring 
out, and as stated in the documentation the callprogress=yes in 
zapata.conf is pretty experimental.

My main problem is that when using the built in call progress 
indicator, it doesn't correctly detect the answered call unless the 
person on the other end has a pretty loud voice and answers several 
seconds before the channel is due to hang up because there has been no 
answer.

I would appreciate any help that we can get on this one as the only 
other choice we have is to go to PRI / E1 which is a more expensive way 
of dealing with the problem.

Kind Regards
Stuart

Stuart,

Just use ISDN BRI. Only a few dollars more per month for 2 lines of ISDN 
than one phone line. There is certified equipment for Australia such as 
the fritz! and others.

POTS can be very unreliable in terms of quality and , of course, tone 
detection. Call progress is spot on perfect with ISDN. You can play 
music or a ringing tone to the caller until the exact moment the other 
end picks up.

Regards,
