Summary:                    SIP OPTIONS qualify message forever
Description: 
Hello, I have a trouble with different Asterisk versions (1.4.26, 1.4.27,
1.4.27.1). When I use the steps below, Asterisk starts to send SIP OPTIONS
to the previous IP/port used by a SIP realtime peer (that has been pruned)
and will keep trying to send SIP OPTIONS pings forever, event if the peer
is connected with a new IP/port address.

I have just checked with my old Asterisk 1.2.27 with the same sip.conf and
I do not have the problem, the SIP OPTIONS stops once register timer has
expired.

During my experience to reproduce the bug, I have been able to have 10
IP/port currently pinged by the Asterisk server for one single peer.
And the only way to stop it is to restart Asterisk...

Thank you for your attention!

jpeeler - sorry for lateness (been working 'away').

Anyway, unfortunately I can not give access to this particular site as it
is not 'net' facing.

Also, I need to qualify (no pun intended) my use of 'every time'.  By
'every time' I mean 'every time on this customers site'.  Not on every one
of my * switches (sorry).

This happened again this morning - and generated 3.5Mb/s this time.  It's
as though the qualify's are getting queued up and then being sent out in
'burst' mode (ie. all at the same time).  Is this how the qualify works in
1.4.3x?

And to add - still in 1.4.35 :(

I think I need to read up on exactly how/often * sends out qualify OPTIONS
packets so I can explain myself more clearly.
