Summary:                    Asterisk gives up on registration after receiving
408 Timeout response once
Description: 
I have noticed the following behavior:
- Asterisk registers fine to SIP provider for days
- SIP provider sends one 408 response due to some temporary issue on their
network
- Asterisk never attempts to register again, until it is restarted,
resulting in loss of inbound service

Ideally, a 408 should never happen.  However, there are hundreds of
possible reasons a provider may send a 408 for a few seconds (systems are
failing over to backups, database is unavailable due to backup, whatever). 
Asterisk should just reschedule registration as it does with all other 4xx
errors.

Any chance of this bug fix making it in?  To clarify, this is not due to a
client-side Asterisk configuration error that might cause other 4xx errors
(like a wrong username/password).  This is due to a momentary glitch on the
remote side, which causes them to properly send a 408 Timeout, so the
client doesn't wait forever.  However, that doesn't mean the client
shouldn't try again shortly.  

I suspect this is not a more visible issue because most ITSPs are letting
Asterisk users connect to Asterisk servers, which, to my knowledge, never
send a 408 regardless of how long the database lookup takes.  However, to
interop with other SIP gateways, Asterisk should be able to gracefully
process a timeout and just try again.
