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

Hi Greg,
There are a lot of installation instructions that I have to write before it 
can run somewhere else then my development system. It requires Apache Axis, 
Java Runtime and Eclipse platform. I will write that down at some point. 
Then it will be possible to share the code.

There is not much on the coding side really. Calls are initiated by .call 
files. All of them go on the same conference extension. That takes care of 
call creation. Then I open several manager connections and monitor them to 
check on the status of each of the lines connected to conference.

Currently I use Digium cards from DIgium developer’s kit to connect analog 
phones via FXS and Avaya PBX via FXO. I also use SIP phones (Pingtel Xpressa 
and Xlite) in conference call. There is not SS7 there unfortunately.

I know that * can identify incoming fax call. Can it do the same thing if 
call is originated from .call file?
May be the same thing can be done for voice mail terminated call?
