Summary
-------

Currently, all versions of Asterisk will accept any value for Session-Expires in an incoming 200 OK as long as it's parseable as a number.  This includes values less than the local Min-SE and even values less than the RFC-defined minimum of 90.  This patch ensures that calls setup in this scenario are immediately torn down.


This addresses bug ASTERISK-20653.

Thanks,
