Summary:                    IAX2 immediately retries after a failed
registration, causing a flood of failed registrations
Description: 
When one asterisk box (host1) has a line such as:

register => 12345:abc at host2

and no such user exists in host2's iax.conf file, host1 will flood host2
with failed registration attempts using as much bandwidth as it can
consume.

IAX2 REGAUTH loop

IAX was not sending REGREJ to terminate invalid registrations. Instead it
sent another REGAUTH if the authentication challenge failed. This caused a
loop of REGREQ and REGAUTH frames.
