Explanation

Cisco Webex Video Mesh Nodes communicate with Cisco Cloud Media Services using HTTPS over TCP port 443 for signaling. This design allows the nodes to traverse standard corporate firewalls and proxies without requiring special port openings. Port 443 is the standard HTTPS port, making it firewall-friendly. Standard SIP (port 5060) and SIP TLS (port 5061) are not used for Video Mesh Node-to-cloud signaling. Port 444 is not a standard Webex signaling port. The use of HTTPS/443 is consistent with Cisco's cloud-first architecture for Webex hybrid services.
