Summary:                    1.2.31.1 changes create storm of IAX2 register
authentication retries
Description: 
The changes on chan_iax2.c from 1.2.30.4 to 1.2.31.1 created this bug:

If "A" tries to register on "B" and the RSA key from "A" does not match
the key on "inkeys" on "B", "B" do not send a "REGREJ", instead it sends a
"REGAUTH" with a new "CHALLENGE", then "A" send a new "REGREQ" for this
"CHALLENGE" with the same wrong RSA key and it loops forever on this (with
a storm of REGREQ <--> REGAUTH packets).

The console from the server ("B") will be flooded with this:
