So, I already have the integration working on production in the company's service I work on. It's generally working smoothly. I'm using the "/restapi/v1.0/account/~/telephony/sessions" webhook subscription.
Nonetheless, I've just spotted a curious case where none of the events' payloads of the same call (they are 5 in total) has the `extensionId` inside the "parties" fragment of the payload, so I can't properly tell what's the call direction (among other things) and that is messing up with our call event processing logic.
Any idea on what to do or how to handle this case?
