A CANCEL request sent from my Asterisk UA (10.1.21.44) to FS (b-lab-1) while the call is still ringing does not work.
 
Why is this request resulting in a 481?
 
I appreciate the help - I'm still just starting to learn SIP & FS.  The CANCEL request and 481 response appear as follows on my FS console:

This means we could not match the cancel to a current call dialog. I would need to see the full sip trace of the call to know why, but typically this is because of not matching call Id or to or from tags

I note that its missing the to tag from the 180 sent 5 seconds earlier (I think thats okay) but the via branch tag is also different, which seems wrong. Can anyone else chime in, I can't recall the dialog matching rules of early dialog like this.

This appears to be a bug in FreeSWITCH. Can you please test this on current svn trunk and if it is still a problem, please report this as a bug to http://jira.freeswitch.org.

Mike,
 
Thanks for taking the time to look at this - I appreciate it.  I'll go ahead and test it out on the current svn trunk.
