[Freeswitch-users] Hangup causes

[Muhammad Naseer Bhatti]

I think 480 is because as mentioned in the wiki "Unspecified causes 
codes (no value in the "SIP Equiv." column in the table) are translated 
to SIP "480 Temporarily Unavailable" by FreeSwitch." But why in this 
case both Q.850 and SIP Equiv cause not matching?
