[Freeswitch-users] Hangup causes

Got a little confusion here.
FreeSWITCH log: http://pastebin.freeswitch.org/21226
SIP trace: http://pastebin.freeswitch.org/21227

Both were taken once after each other but other than the timing, 
everything else remains the same.

This is a vanilla install for FreeSWITCH Version 
1.5.5b+git~20130724T035836Z~3ae87091e1 (git 3ae8709 2013-07-24 
03:58:36Z). Just dialing a non existent number (98871002) from a 
registered user 1001. The hangup cause returned by the switch shows
mod_sofia.c:463 Channel sofia/internal/1001 at hanging 

However the SIP capture shows SIP/2.0 480 Temporarily Unavailable. This 
480 is also showing by the switch mod_sofia.c:597 Responding to INVITE 
with: 480. I know the mapping is done by FreeSWITCH. In this case why 
480, returned Normal Temporary Failure while the switch shows 
NORMAL_CLEARING? Is this because Q.850 returned is 16 and FreeSWITCH 
mapping for 16 is NORMAL_CLEARING?

Or is there something I am missing.
