Summary:                    SIP registration with a high latency peer fails
Description: 
I have 2 snom phones same config (via config server) and same firmware. 
One is 20ms latency, the other is 650ms.  The 650ms seems to authenticate
and then be challenged again.  The 2nd attempt fails (as below).  No such
issue with the 20ms one.

The issue does not maninfest with asterisk-1.6.1.4 (compiled from source)
but does with the latest SVN.

The happens 100% of the time.

I've attempted to adjust timeouts in sip.conf and chan_sip.c, but
truthfully I'm hacking about beyond my understanding.  Nothing worked.

I did look at diff ./asterisk-1.6.1.4/channels/chan_sip.c
./asterisk/channels/chan_sip.c, but it's (again) a little beyond me.

I have this replicateable in a test environment so I can test scenarios if
necessary.
