Re: [Asterisk-java-users] manager events

[Paul F. <pa...@sm...>]

Hi Stefan,

Thanks for your reply. I think I explained my idea poorly. What I  
meant to say was that in a complex app where you initiate a call  
using the Manager API, and then communicate back and forth with  
Asterisk by sending AGI commands from the dialplan -- instead of  
using AGI, could it be possible to instead communicate back to the  
Asterisk-Java app (from the DIalPlan) using this new UserEvent  
mechanism? So my question was not really about changing the way calls  
are initiated -- they would still be initiated via the Manager API --  
but was whether a more event-based way of communicating back to the  
Java app could be accomplished by sending UserEvents instead of the  
calling back to the AGI server. In thinking about it more, it seems  
like it would probably not work too well, since AGI provides commands  
for doing things directly in Asterisk. Without those AGI commands it  
might be pointless, but I wasn't sure if the events triggered by the  
UserEvent could be used to call back with the Manager API and create  
a Java to Asterisk conversation that way.

Anyway, this questions is more out of curiosity. Currently, my  
Manager/AGI solution works very reliably, but I am continuing to  
think more about building a CCXML framework on top of Asterisk-Java  
to provide a a higher level of abstraction for doing call control,  
and was wondering if the UserEvent thing might provide a more  
seamless way of providing the Asterisk to Java conversation that will  
be necessary in getting a CCXML solution to work. Any other ideas on  
how to go about building this?

Thanks again for developing such a great framework!

Best Regards,

Paul

The UserEvent is used to send arbitrary events FROM Asterisk (i.e. from
the dialplan) to your Manager API based application.

No, you cant use it for that purpose. To originate a new call there are
only two possibilities: The Manager API and .call files. The prefered
way is the Manager API.
