[asterisk-users] Answering machine answers after pickup a phone.

Fri Aug 5 05:44:02 CDT 2011

You should change in dahdi conf the amount of time (rings) it should wait before answering

The dialplan doesn't handle that

Hi!

I'm sorry that I have misundertood your question, didn't read it
carefully enough.
So you have your asterisk and your phone conntected to the same incoming
line.

Maybe you can try with to detect an answered call with BackGroundDetect()

exten => s,1,Answer()
exten => s,n,BackGroundDetect(silence/10)
exten => s,n,Voicemail(1234)

exten => talk,1,HangUp()

I can't try it for your setup with a POTS line, but I think this might
work, especially when you tune the time values for BackGroundDetect().

Quote of the manual:

--- SNIP ---
 -= Info about application 'BackgroundDetect' =-

[Synopsis]
Background a file with talk detect

[Description]
  BackgroundDetect(filename[|sil[|min|[max]]]):  Plays  back  a  given
filename, waiting for interruption from a given digit (the digit must
start the beginning of a valid extension, or it will be ignored).
During the playback of the file, audio is monitored in the receive
direction, and if a period of non-silence which is greater than 'min' ms
yet less than 'max' ms is followed by silence for at least 'sil' ms then
the audio playback is aborted and processing jumps to the 'talk' extension
if available.  If unspecified, sil, min, and max default to 1000, 100, and
infinity respectively.

Hope this helps.

regards,
Ruben
