Re: [Asterisk-java-users] originateCall in AsteriskManager

[Stefan R. <sr...@re...>]

Hi Tony,

these are two very good questions :)
What I thought of was to make to call to originate asynchronous so that
you could pass it some kind of callback (maybe just a property change
listener) that is called on changes to the originated channel.
What do you think?
