I have a dedicated VLAN for Zoom phones and I have created firewall policy to allow some ports based on the "https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0060548" but still we are getting not connected to Zoom phone server error. Ports allowed from the VLAN as source and ports (80,443,390,5091,8801-8810,3478,3479. Is there any document showing how to configure Zoom phones.
