Hi, Sergej,
I'm a begginer in jabber app's development, so I'm learning trying anf 
When I send some xml to the server, I wait for a response in a bucle, 
something like this:
for($i=0; $i<NUM_RETRIES; $i++) {
	$line = $this->receive();
         if (!empty($line)) {
         	return true;
Obviously, it's not the better way, but I'm learning by the moment.
