[Freeswitch-users] hangup a call with a specific reason

Hello, In case of an incoming call from PSTN to FS that is bridged to a user, if user is not answering in 60 seconds FS will close the call with 480. I find in config how to configure this timeout to larger value but I didn't found anything on how to overwrite the reason in 486. Some carriers are rerouting the call over and over again in case they get 480 and behavior sucks for the users Silviu
