I've just had a look, and can confirm that it is working here... even quite
a while after the fring client has been closed :/

Fring seems to send CR and LF twice in one packet every 10 seconds, not
relevant here, but, a bit odd...

One thing that might be relevant, it does use NAT, at least some of the
time, so asterisk needs to be aware of that... Address combinations I've
seen in the past hour...
