[Asterisk-Users] Web service to start a conference and voice mail

[fabian at gigacodes.de]

Hi,
As far as is know, there is no perfect solution for this problem.
Some people worked out an math algorithm that tries to detect an
answering machine.
But this just bases on the fact, that an answering machine takes more
time to answer (speak the first tone),
than a real person. And therefore it's not very accurate. 
I'm not aware of any other technique to discover an answering machine /
voicemail...

Hi
I have written a web service that starts a conference call and then
monitors 
call progress on the manager interface. It works nicely until conference
in 
a voice mail system. It would be better if I could intercept the fact
that 
the answering side is a voice mail and not to conference it in. The same

thing might happen with fax or modem, but I have not seen that happening

yet.

Is there a way to identify when if there is a voice mail machine of the 
line, fax or a modem?

Thank you
Serge
