Summary:                    [patch] Asterisk fails to recognize SUBSCRIBE
retransmissions and tries to re-authenticate them, which breaks presence on
polyco
Description: 
Here's what happens from asterisk point of view:
-> SUBSCRIBE
<- 401 Unauthorized
-> SUBSCRIBE with auth
<- 200 OK (lost)
<- NOTIFY
-> 200 OK for NOTIFY
-> SUBSCRIBE with auth retransmission
<- 401 Unauthorized
At this point polycom phone received 2 "401 Unauthorized" in a row and it
completely gives up on resubscribing to this hint until reboot. While
polycom behavior is questionable, I believe asterisk should recognize
retransmission and resubmit 200OK in this case

  Don't authenticate SUBSCRIBE re-transmissions
  
  This only skips authentication on retransmissions that are already
  authenticated. A similar method is already used for INVITES. This
  is the kind of thing we end up having to do when we don't have a
  transaction layer...
