[Freeswitch-users] Hangup causes

[Steven Ayre]

Missed you'd included the logs ;)

As suspected, the 480 contains 16 so that's where normal clearing comes from

480 temporary failure is the SIP cause
16 Normal Clearing is the ISDN Q850 one

Internally FS will use ISDN causes and map protocol specific ones between
them (which isn't 1:1), Reason lets the endpoint override that mapping
because its already providing the exact one
