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

[Serge Mankovski]

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
