Committed in revision 431187
Bugs: ASTERISK-24715
https://issues.asterisk.org/jira/browse/ASTERISK-24715
Repository: Asterisk
Description
-------
When refreshing (with a small expiration) a registration that was sent to
chan_sip the nonce would be considered stale and reject the registration. What
was happening was that the initial registration's "dialog" still existed in the
dialogs container and upon refresh the dialog match algorithm would choose that
as the "dialog" instead of the newly created one. This occurred because the
algorithm did not check to see if the from tag matched if authentication info
was available after the 401. So, it ended up assuming the original "dialog" was
a match and stopped the search. The old "dialog" of course had an old nonce,
thus the stale nonce message.
This fix attempts to leave the original functionality alone except in the case
of a REGISTER. If a REGISTER is received then the from tag is always checked
thus allowing the correct "dialog" to be selected.

Testing
-------
Setup two asterisk systems, one to register and one to accept registers.
Specified a small expiration in the configuration file and then watched as the
primary system registered successfully to the secondary system. Then upon
refresh saw the notice message and received a registration rejection message.
Applied the fix and the problem no longer occurred.
Thanks,
Kevin Harwell
