There is a SESSION_HEARTBEAT event that you can monitor to see if FS has stopped responding. It also has a lot of other useful information. Guillermo On Thu, Nov 11, 2021 at 8:56 PM Telium Technical Support <support@telium.io> wrote:
No crash, just learning how to use the ESL. I strongly prefer async design, so wondering if connect and disconnect have some sort of success/failure callback.
Or is the only way to check success to send a command over the socket?
Same with disconnect, do we need to wait for a send failure?

If you have a crash you should perform a back trace and submit an issue on github.

I’m trying to figure out asynchronous use of the ESL (from C). If I call esl_connect_timeout with a timeout of 0, what happens if the connection is not made immediately? Is there some callback function indicating success/failure?
If the esl connection is lost (FreeSwitch crashes), is there a callback function indicating the lost connection? Or do I need to issue a status/keepalive to ensure function succeeds?
Looking a bit at the esl.c code I’m wondering if the above are synchronous only…(polling for status)
