Description:	When using RFC 4028 with chan_sip, an INVITE from Asterisk may be replied with 422, in order to negotiate session timers. When the 422 is received, if Asterisk hangs up the channel before a final response (200 OK or other) is received, no CANCEL request is sent. Detailed steps to reproduce : - Given SIP Session timers are enabled - Given Asterisk does a Dial() to an RFC 4028-compliant endpoint - Given Asterisk receives a 422 response and Asterisk replies to it - Given Asterisk receives a 100/180 response - When Asterisk hangs up the channel (before it has been answered with a 200 OK) - Then Asterisk does not send a CANCEL request Expected : Asterisk sends a CANCEL request I am going to submit a fix on Gerrit.
