> I am using the api_hangup_hook variable to let my internal system know when<br>

><br>
> Every now and then my calling party cancels the SIP Invite before my dial<br>
> plan is finished. IN this case FreeSWITCH properly responds with a "487<br>

><br>
> However, this does not fire the command assigned to the api_hangup_hook<br>

> My question is whether there is a place somewhere where I can hook into the<br>
> processing of the CANCEL SIP message.<br>
