[Freeswitch-users] Unanswered pstn outbound call via gateway detection

[Ciprian Dosoftei]

Tanim --

Since you are using ESL, you should monitor the status of the outbound
channel you've originated -- you should do that by channel ID, either the
generated one or you could preset it via the origination_uuid variable.

During the channel's execution you will see a bunch of CHANNEL_* events
streamed via ESL; the relevant event for your question is CHANNEL_HANGUP.
You can extract the reason behind the hangup from the Hangup-Cause header
(could be CALL_REJECTED, USER_BUSY etc. here's a comprehensive list
https://freeswitch.org/confluence/display/FREESWITCH/Hangup+Cause+Code+Table
).

Conversely, if the call is picked up, you will see a CHANNEL_ANSWER event
coming through.
