New Revision: 377626

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=377626
Log:
Handle Session-Expires less than local Min-SE in 200 OK

Ensure that a call is immediately torn down if a Session-Expires value
received in a 200 OK is less than the local Min-SE. This also prevents
Asterisk from allowing calls with Session-Expires below the
RFC4028-mandated minimum (90s).

(closes issue ASTERISK-20653)
