Welcome to the RingCentral Community

Hi, I have a subscription to the telephony events of my client, who is the Five9 customer. On the events I received via the webhook, for inbound calls, in the "to" party object, some have and extensionId, which I gather identifies the agent, and is what I need. However, some do not have extensionId, and I wonder what that means. For those, I do still have the called phone number, but not the extensionId.

Thanks!
