I can only seem to find features that trigger an action when a call is received by the app, and not when a call is answered. This means if you have RingCentral set up to do round-robin, if a call gets passed between a few agents, you get lots of duplicate triggers/actions.
With RingCentral's existing webhook features, I suspect it's possible to build a RingCentral app that triggers a webhook on a call being answered, and I've been poking around in the developer portal trying to do it myself but I've only gotten as far as making a few successful API calls (I'm a novice, so I could probably do it but it'll take me a long time).
Has anyone else built this? I wouldn't be surprised if it's out there, or if there's something very similar that I could modify to fit my needs. Searched around, but I haven't found anything yet.
