    I tried this setup, however the part about adding Translation Patterns with the “!” twice is not allowed. I would love to do this if anyone can provide more details.

      I believe that you might have added “!” pattern twice with same partition/null partition. The actual work is to add “!” with two different partition, i.e., Gateway_PRT and Filter_PRT. Let me know if you face any issues?

      Hi Mostapha,

      To achieve the above scenario, you need to play with Partition and CSS.

      Create 3 Partition and 3 CSS (Staff_PRT, Staff_CSS, Manager_PRT, Manager_CSS, Assistant_PRT, Assistant_CSS)
      1. In Staff_CSS > Assign Staff_PRT and Assistant_PRT
      2. In Manager_CSS > Assign Staff_PRT, Assistant_PRT and Manager_PRT
      3. In Assistant_CSS > Assign Staff_PRT and Manager_PRT
      4. Now in Manager’s IP Phone > Assign Manager_PRT and Manager_CSS
      5. Now in Staff’s IP Phone > Assign Staff_PRT and Staff_CSS
      6. Now in Assistant’s IP Phone > Assign Assistant_PRT and Assistant_CSS

      That’s all. Let me know if you are facing any issues.
