I looked at the ESL C code and I *THINK* that I have to poll using the esl_recv_event_timed function (to look for the SESSION_HEARTBEAT event). Is there already a callback function that I can hook into to be notified of events? If not, at which frequency should I poll for events (sleep inbetween) based on anyones experience? I don’t like blocking code so I’m hoping there is already a callback function setup. Or is there some other way to handle this?

It also has a lot of other useful information.

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 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) _________________________________________________________________________ The FreeSWITCH project is sponsored by SignalWire https://signalwire.com Enhance your FreeSWITCH install with disruptive priced SMS and PSTN services.
