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!

Hello again, I have the same problem on a running 1.4.26 server. It is
flooding a sip peers that is not connected anymore on the platform. I have
previously tested the 1.4.29 but the bug described above was still
present.

The problem is not present on asterisk 1.2.x and 1.6.x but the upgrade
will be very complicated for me since I will have to change the database
entries with the new syntax...

reload chan_sip.c doesn't stop the flooding, only a restart solve the
problem.

As suggested by "zerohalo" and "dtyoo", is there something I can do to
help developpers understanding what's wrong?
Best Regards
