>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/General
>    Affects Versions: 13.7.2, 14.3.0
>         Environment: Centos 7
>            Reporter: Jean Aunis - Prescom

> 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.
