You have to remember that FreeSWITCH isn't a sip stack but Sofia-SIP  
is our stack of choice.  I suspect that the NUA layer isn't passing  
this up to our layer to deal with.  I'm sure we'll have to bring this  
to their attention for a fix ;)  But you can open a bug on this at  
jira.freeswitch.org.

Thanks,
Brian
