[Freeswitch-users] continue_on_fail triggered by NORMAL_CLEARING

Tue Jul 17 19:28:20 UTC 2018

I think I finally identified the problem.

I wasn't setting hangup_after_bridge=true

If that's the case....

Is there any scenario where setting continue_on_fail=true and
hangup_after_bridge=false makes sense? If not, would the FreeSWITCH be open
to a patch that at least emits a WARNING when this scenario occurs

Can the following page be modified to mention that you probably want to set
hangup_after_bridge=true for this setting to take effect?
