Many problems encountered in a video deployment could be network related. Performance of your video deployment relies upon bandwidth, firewall, media flow and QoS. These can impact user-experience and must be properly evaluated and addressed.
Areas for consideration
Network configuration requirements for video services can be grouped into the following categories:
Connection must support the Webex service
Use the to check the status of the customer network, specifically for the speed of the network using TCP and UDP, and port connectivity.
Allowing UDP vs TCP traffic
Availability of bandwidth
Before, consider the number of SIP endpoints registered to Cisco Unified CM and the available Internet edge bandwidth per site
Check QoS policy, review Cisco Webex guidance on QoS best practice
Network configuration (link to network document on help.webex.com)
Check whitelisting of Webex domain services
Configure Proxy to allow access to Webex Cloud services
Webex Edge for Device requires https and does not require additional ports or infrastructure
Through proper planning and design before deploying your video system, you can reduce the amount of effort that will be required to maintain high-quality experiences.
