Hey,
I posted this earlier as a question, but I think this might be relevant.
ttp://pastebin.freeswitch.org/20508 <http://pastebin.freeswitch.org/20508>.
The workaround (hack) for my issue is to check the connection state
($con->connected()) every time you loop and reconnect and subscribe for
events again when that returns false.
