![Microsoft Teams: UDP Signaling Ports configuration change [MC898392]](https://mwpro.co.uk/wp-content/uploads/2024/08/pexels-jplenio-1125769-1024x683.webp)
Coming soon: To enhance the efficiency of Microsoft Teams, we will implement a significant update to the UDP signaling ports used for Calling and Meetings.
Before this rollout, Teams uses UDP Source Ports 49152-65535 for Calling and Meetings signaling API Calls. This includes functionality such as mute/unmute, hold, adding participants, and reactions.
After this rollout, Teams will transition UDP signaling from source ports 49152-65535 to 50070-50089, maintaining the destination UDP port 3478. This change aims to reduce the number of ports used and enable you to apply Quality of Service (QoS) DSCP markers to this traffic.
When this will happen: General Availability (Worldwide): We will begin rolling out early October 2024 and expect to complete by early October 2024.
[What you need to do to prepare:]
Allow UDP Source Ports 50070-50089 to Destination Ports 3478 to 52.112.0.0/14, 52.122.0.0/15, 2603:1063::/38 (ID 11, Optimized Category for Microsoft Teams). Since the new range is a smaller subset inside of the existing ranges, no changes should be required for admins currently allowing UDP signaling.

The upcoming update in Microsoft Teams regarding the UDP signaling ports is here to shake things up a bit! Admins and users, get ready for a smoother and more efficient Teams experience.
Admins, you’ll be pleased to know that this change aims to simplify things by transitioning UDP signaling to ports 50070-50089 while keeping the destination port at 3478. This means fewer ports to worry about and the ability to apply Quality of Service (QoS) DSCP markers to the traffic. So, get ready to sail through those calls and meetings with ease!
Users, this update will work behind the scenes to make your Teams interactions snappier and more reliable. From muting/unmuting to adding participants and throwing in reactions, everything will be smoother than a well-oiled machine.
In terms of criticality, this update is pretty important for ensuring a seamless Teams experience. So, make sure to prepare by allowing UDP Source Ports 50070-50089 to Destination Ports 3478 to the specified IP ranges. But hey, no need to stress too much, as this change shouldn’t require much adjustment for admins already allowing UDP signaling.
So, mark your calendars for early October 2024 when this update will start rolling out worldwide. And remember, smoother calls and meetings are just around the corner!
