I’d like to make a web application or an windows application which gets notified for the events related call incomming, hangup, dialing from FreePBX(or asterisk).
When a call is incomming, I’d like my application gets notified with caller ID, caller phone number.
To do this I think REST API wouldn’t be enough. Is there any APIs for doing this?
If I try this with REST API, endless polling would be needed. I guess there should exist some other API for receivng async event notification messge.
Thank you very much in advance!
