Hi guys, Thank you very much for your help. I don't know how, but the issue has been resolved. Maybe this case will be useful for somebody else. So, my iMac and Meraki MR30H were configured at the company to connect to internet via VPN. I didn't have any access to iMac/Meraki configuration settings. Meraki was connected via 10m cable to vDSL modem TG589vn v3 Port 1; Avaya hardphone was connected to port 1 of Meraki and iMac was connected to Meraki Port 2. After several attempts to connect Meraki was replaced with the same results. The issue was escalated to network engineers of my company as well as to ISP's ones. ISP advised me to upgrade my modem to a later version paying just for urgent delivery. Company engineers were trying to find a solution on their side. Finally, I don't know who found a solution, but on Friday night I have had connected Meraki to Port 4 of my router (tried it before multiple times) and everything worked! In any case I will upgrade my router tomorrow to be on secure side. Thank you again! Best regards, Geheimen.
