How to block numbers RRS feed

  • Question

  • Hello Everyone,

    I have been tasked with finding a way to block incoming numbers.  I found the below articles however I have a few issues/concerns.

    Has anyone found an easy way to block incoming numbers via Skype for Business or a AudioCodes Gateway?

    If so, what is your experience with blocking number in Skype for Business and how are you doing it?


    This article is the preferred method because we can put the ownership on the user and only block a certain number for a user.  However I am not able to get an Outlook contact in Skype for Business contact list to change from Auto-Assign Relationship to Blocked Contacts Relationship.  The Privacy Relationship always stays on Auto-Assign.  I can change contact that are within our org and even external federated contacts.  Just not contacts I had via Outlook.  I suspect its because of the Unified Contact Store?  Anyone else have this issue?


    The article is good as well but I do not like the idea of making server side changes just to block a few numbers and I would rather not have to manage a list.

  • Hi lan,

    Welcome to our forum.     

    We suggest you block incoming numbers using AudioCodes gateway using the following link, because it will reduce voice flow between AudioCode and SFB server:
