Hi Michael,

This is probably a good venue for your question. I think Stefan and I 
may have even discussed the choice, at some point, of exposing the 
channel manager directly. However, I think that, at least in my context, 
I ended up not needing to expose the channel manager to solve my problem 
-- resyncing channels.

I believe, in my case, I simply fed the state events to the 
asteriskServer by directly calling onNew... with my own event objects.

My resync looked something like this:

Collection<AsteriskChannel> channels = asteriskServer.getChannels();

for(AsteriskChannel channel : channels) {
   onNewAsteriskChannel(channel);

   if(channel.getLinkedChannel() != null) {
     AsteriskChannel linkedChannel = channel.getLinkedChannel();
     PropertyChangeEvent propertyChangeEvent = new 
PropertyChangeEvent(channel, AsteriskChannel.PROPERTY_LINKED_CHANNEL, 
null, linkedChannel);
     propertyChange(propertyChangeEvent);
   }

}


Does that work for you? I want to say there's some code floating around 
in the implementation of the DefaultAsteriskServer that does something 
similar...

Cheers,

Martin
