This guide is designed to provide firewall recommendations for settings and port openings. Evolve strides to provide the most ideal settings for the most common firewalls. However, knowing the exact settings for customer firewalls, IT vendors, and ISP carriers is the responsibility of the customer and their contracted IT vendors

Network Requirements for Webex Services
https://help.webex.com/en-us/article/WBX000028782/Network-Requirements-for-Webex-Services#id_134894
Document Revision History
This article is intended for network administrators, particularly firewall and proxy security administrators who want to use Webex messaging and meetings services within their organization. It will help you configure your network to support the Webex Services used by HTTPS based Webex app and Webex Room devices, as well as Cisco IP Phones, Cisco video devices, and third-party devices that use SIP to connect to the Webex Meetings service.
This document primarily focuses on the network requirements of Webex cloud registered products that use HTTPS signaling to Webex cloud services, but also separately describes the network requirements of products that use SIP signaling to join Webex Meetings. These differences are summarized below:
...
The following table describes ports and protocols that need to be opened on your firewall to allows cloud registered Webex apps and devices to communicate with Webex cloud signaling and media services.
The Webex apps, devices, and services covered in this table include:
The Webex app, Webex Room devices, Video Mesh Node, Hybrid Data Security node, Directory Connector, Calendar Connector, Management Connector, Serviceability Connector.
For guidance on ports and protocols for devices and Webex services using SIP can be found in the section "Network requirements for SIP based Webex services".
Webex Services - Port Numbers and Protocols | |||
Destination Port | Protocol | Description | Devices using this rule |
443 | TLS | Webex HTTPS signaling. Session establishment to Webex services is based on defined URLs, rather than IP addresses. If you are using a proxy server, or your firewall supports DNS resolution; refer to the section "Domains and URLs that need to be accessed for Webex Services" to allow signaling access to Webex services. | All |
444 | TLS | Video Mesh Node secure signaling to establish cascade media connections to the Webex cloud | Video Mesh Node |
123 (1) | UDP | Network Time Protocol (NTP) | All |
53 (1) | UDP TCP | Domain Name System (DNS) Used for DNS lookups to discover the IP addresses of services in the Webex cloud. Most DNS queries are made over UDP; however, DNS queries may use TCP as well. | All |
5004 and 9000 | SRTP over UDP | Encrypted audio, video, and content sharing on the Webex App and Webex Room devices For a list of destination IP subnets refer to the section "IP subnets for Webex media services". | Webex App Webex Room Devices Video Mesh Nodes |
50,000 – 53,000 | SRTP over UDP | Encrypted audio, video, and content sharing – Video Mesh Node only | Video Mesh Node |
5004 | SRTP over TCP | Used for encrypted content sharing on the Webex App and Webex Room devices TCP also serves as a fallback transport protocol for encrypted audio and video if UDP cannot be used. For a list of destination IP subnets refer to the section "IP subnets for Webex media services". | Webex App Webex Room Devices Video Mesh Nodes |
443 (2) | SRTP over TLS | Used as a fallback transport protocol for encrypted audio, video and content sharing if UDP and TCP cannot be used. Media over TLS is not recommended in production environments For a list of destination IP subnets refer to the section "IP subnets for Webex media services". | Webex App (2) Webex Room Devices |
(1) If you are using NTP and DNS services within your enterprise network, then ports 53 and 123 do not need to be opened through your firewall.
(2) The Webex Web-based app and Webex SDK do not support media over TLS.
