[Asterisk-Users] Problem calling out

[Warren Burstein]

I see these from time to time, I think it means that packets got lost, 
or received out of sequence.  It looks to me like asterisk manages to 
deal with this, so unless your calls have also stopped working, I 
wouldn't worry.  (If we should be worrying, I expect someone will let us 
know).
