Hi Peter
1) how to config callprogress=yes ? in extensions.conf? could you give me an 
example?

Not in extensions.conf, but in zapata.
http://www.voip-info.org/wiki-Asterisk+config+zapata.conf

In my case, busydetect=yes and busycount=5 were the key to getting it right.


2) you means record the call (via zaptel) into a file and analyze it with 
audio tool?
In my case it was simpler. I had trouble with detecting the busy tone. So 
when I called the voicemail, it didn't detect the hangup, thus it kept 
recording the line (with the tone) until the tone stopped or the VM got 
tired of waiting. Then I received the WAV in my email... so in short I did 
not need to record it.

Now, if you are detecting the busy tone, right, then you can record either 
by zaptel (I really don't know how) or an easier way, through the sound card 
of the machine you are calling from with a iax/sip softphone. Usually it is 
as easy as selecting the sound card record mode, and selecting the mixer 
channel.


Now.. indications.conf, seems not only to define how to generate the tones, 
but also how to interpret them. At least, mine only worked once I changed 
those values.

REGARDS!
