What is the API we can use to block a contact in RingCentral from calling me?
I have tried successfully to block a contact number in the desktop application and I was successful in it but, out of the API's available, I am not getting any API that can block number from my phone.
You can use Call-Blocking APIs of RingCentral to block a contact number, update the blocking, allowing a contact, delete a blocked number.
Here is the Call-Blocking APIs:
