        Hi barisr, sorry for the delay. 
        I've spoken to another Dutch VoIP provider. They did some research.

        It comes down to this. They could see, that the autoattendant/service number is visible in the FROM header. But also the usernumber pops up in the SIP message under P-Asserted-Identity.

         

        If we can alter the P-Asstered-Identity. Then we might have a fix. I'm not familiar with this unfortunately. 
        I'll create a support ticket with Microsoft, íf this is possible in Teams Cloud Only. On prem/hybrid there are some commands present.
