Welcome to the RingCentral Community

How to filter out or identify only the incoming calls to a particular extension from Telephony Session webhook. I need to identify it before it ring to the dialled extension(reception extension). Then I will route the call to other extension depending on on my custom logic, with out ringing that reception extension phone.

I have used active call list, but it ring the extension before gets routed to other extension. Can you guide me how can I achieve the expected outcome?

Thank you.
