Summary:                    [patch] When unregistering a UA, 200 OK response
from Asterisk is not SIP compliant
Description: 
When Asterisk is used as a registrar, and a registered UA is sending a
REGISTER with Expires header set to 0, then usually Asterisk will send back
a 200 OK response, containing a Contact header with the contact to be
removed, and an expires parameter that is set to the previous expiration
value!!!
This is not compliant with RFC 3261!

When a SIP peer unregisters set the expiry time back to 0 so that the 200
OK contains an expires of 0.
