What ports do you need open for other remote contributors?

Skype

In addition to the generic port 443 / TCP that we must open for any video call program, those specific to Skype are the UDP ports 3478-3481 and 50000-60000 UDP. These ports must be open on the firewall. Also, as indicated from Skype, to achieve a better image quality experience we can open the ports 1000-1000050000-65000 and 16000-26000 UDP.

 

Zoom

First of all we must have the ports open 80 and 443 TCP, which are the ones that the application will use for the connection. They are generic ports that are usually open, such as 80, which is responsible for allowing an HTTP server to listen (without encryption).

Also, as more specific ports, we must open the ports TCP 8801 and 8802, as well as the UDP 3478, 3479, 8801 and 8802. All of them will influence the connection and will allow us to make a video call without so many problems.

 

Discord

In this case, the ports that we must open, in addition to the 443 TCP for HTTPS connections, it is the TCP port 6463, as well as the TCP and UDP ports 6457-6463. These ports will help the connections work in the most optimal way possible.

 

Facetime

Another program is Facetime. It also has many users who make video calls in their day to day. We can also make sure we have the necessary ports open for the connection to work properly.

In this case we must make sure that we have the port 443 TCP, Besides ports 53, 80, 5223 and 16393-16472 UDP. With them we can get it to work as well as possible and that the dreaded cuts do not appear when we make a call. This can affect both FaceTime and any other application of this type that we use.

 

Teams

For Teams to function correctly, you must open TCP ports 80 and 443 from the clients to the internet, and UDP ports 3478 through 3481 from the clients to the internet. The TCP ports are used to connect to web-based content such as SharePoint Online, Exchange Online, and the Teams Chat services.

 

Webex

Webex utilizes port 9000 for the Webex Events Audio Broadcast feature. If unable to connect, it will use TCP 443.

The Webex client will try to connect to a Multimedia server over UDP port 9000. If unable to establish a connection over UDP 9000, it will use TCP port 443. Due to the nature of TCP and how lost delayed packets are retransmitted, it is not recommended to use TCP. We recommend allowing UDP port 9000 whenever possible. (This media is sent over standard RTP. Firewalls should not manipulate the RTP being sent or received.)
