Re: [Asterisk-java-users] Transfer call to another extension

[Wayne M. <way...@th...>]

Hi,

I use the Live Manager API to do the following.  I have an active 
channels HashMap which holds Channel objects.  When I get a new channel 
I want to deal with, I add it to the active channels list.  Then I have 
the following helper method:

/**
  * Redirects the given channel to the given extension
  * @param channelID Channel to redirect
  * @param to extension to send channel to
  */
public void redirectCall(String channelID, String to){

   AsteriskChannel channel = activeChannels.get(channelID);
   channel.redirect(autoAnswerContext, to, DEFAULT_PRIORITY); 
//autoAnswerContext is part of my dial plan that sets the auto answer 
flags
   //If you want to redirect to a queue use this instead
   //channel.redirect(defaultContext, queueNumber, DEFAULT_PRIORITY);

}

Which all seems straight forward enough, however you mentioned outgoing 
calls which gave me a problem too.  I found the following weirdness to 
be true:

If I create an outgoing call, I will get a couple of channels including 
an initial one for the party I'm calling.

For some reason peculiar to queues, if I then transfer this party to a 
queue the initial channel ID I was holding gets dropped and a new 
channel is generated once the party is in the queue.

At this stage the channel always remains the same no matter what you do 
to the party but this initial channel change confused the heck out of 
me.

Hope this helps, for way more code than is here have a look through:
