Hello,
we are running a breeze cluster (cluster profile "General Purpose") containing two breeze servers (version 3.6.0.2.360203).
We build a callable snapin (sdk version: 3.6.0.1.360106) that receives a call and starts a media playback.
After that the call processing is finished, the calling participant is listening to the media playback.
public void handleInterceptedCall(Call call) {
try {
parkedCalls.put(call.getUCID(), call);
announcementService.playIntro(call, new IntroListener(call, announcementService));
restService.addCallToPool(call); // send ucid to external webapp
logger.info(format("UCID %s - Finished intercept call", call.getUCID()));
} catch (Exception exception) {
logger.error(format("UCID %s - Error occurred while intercepting call", call.getUCID()), exception);
call.drop();
}
}
The snapin provides a rest endpoint, that is used to forward the call to an endpoint.
Via the endpoint the ucid and the target number is provided. With the ucid we want to retrieve the call from Breeze.
public Call getCall(String ucid) {
return com.avaya.collaboration.call.CallFactory.getCall(ucid);
}
// after the call is requested, media playback should be stopped and the call is forwared to the targetNumber
pbulic void executeTransfer(com.avaya.collaboration.call.Call call, String targetNumber) {
logger.info(format("UCID %s - Forwarding call to target %s", call.getUCID(), targetNumber));
announcementService.stopPlayback(call);
parkedCalls.remove(call.getUCID());
com.avaya.collaboration.call.Participant participant = createParticipant(targetNumber, call);
call.addParticipant(participant);
}
If both server are available, the snapin works as planed.

But if one of the server is removed from the network (this way we want to test the cluster setup), the snapin fails to retrieve the call:

Any idea what could cause this behaviour?
Kind regards,
