The Webex app can also use the SIP protocol to join Webex meetings, but this is subject to the user either being called via their SIP address or choosing to dial a SIP URL to join a meeting (rather than use the functionality of the meeting native to the Webex app).

The Webex App uses HTTPS signaling for Webex messaging and meeting services.

This feature allows Webex devices to be administered via Webex Control Hub and to participate in Webex Meetings using HTTPS signaling (for details see ).

On-premises SIP registered Webex devices can also use HTTPS signaling if the Webex Edge for devices feature is enabled.

Cloud registered Webex Room devices use HTTPS signaling for all Webex services.These differences are summarized below:Īll cloud registered Webex apps and devices use HTTPS to communicate with Webex messaging and meetings services: 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. 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.Ĭhanges to IP subnets for Webex media services and URLs for Webex services are generally published 30 days in advance of being activated, but may also be updated at shorter notice if needed to address support escalations, security incidents, or other immediate operational requirements.

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.
