Teams often open broad network ranges to get chat and bots working fast. They allow wide outbound traffic from internal servers and cloud networks. When network rules are too wide, internal bots and apps gain too much reach. A single compromised bot can then touch internal databases and production servers.
How microsoft teams ip addresses and ports work
The chat app splits network traffic into three main paths. First, core web traffic handles user sign-in, text chat, and file sharing. Second, real-time media traffic carries voice calls, video streams, and screen sharing. Third, webhook and bot traffic connects the chat service to your internal tools.
Network admins must allow outbound traffic on standard web ports for text and sign-in. Voice and video streams need specific high UDP port ranges to prevent audio lag. If your firewall blocks UDP, the app falls back to standard TCP web ports. This fallback keeps calls running, though video quality often drops during busy hours.
Teams also build chat bots that trigger tasks inside private cloud networks. To run these bots, engineers open inbound or outbound paths to cloud endpoints. The firewall checks the source address and destination port before passing the packet. Once the packet clears the firewall, the bot talks to internal databases or servers.
Why firewall rules should bypass media inspection
Many security teams route all outbound web traffic through deep packet inspection tools. This setup works well for normal web browsing, but it breaks real-time voice calls. Inspecting live audio packets adds delay and causes voice drops during team meetings.

To fix this, admins map the official cloud voice subnets in their firewall rules. They set the firewall to route traffic for those specific addresses straight to the internet. Text chat and file uploads still follow standard security rules. Meanwhile, live audio and video packets take a direct, fast path out of the network.
What network rules solve and what they miss
Good firewall rules keep your voice calls clear and block unknown outside hosts. They make sure only real cloud chat servers can reach your bot endpoints. This setup stops random internet scanners from hitting your internal webhook listeners.
Still, IP lists and port rules only check where traffic comes from. They do not check who is inside the chat room or what command runs. Once a chat bot connects to a database or server, network rules stop helping. If a bot uses a shared database key, any user in that channel has full power. A bad query or script can still read phone numbers or drop production tables. Network rules decide which servers can talk, not what individual commands do in flight.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Why do voice calls drop when web chat still works?
Web chat uses standard TCP web ports, which most firewalls allow by default. Voice calls need UDP port ranges, and packet inspection tools often block or slow them.
How often do cloud chat network ranges change?
Cloud providers update their IP ranges as they add new data centers. Network teams should check the official published address list each month and update firewall rules.
Do chat bots need inbound firewall ports open?
Many webhooks need an inbound web port open from the cloud service range. Some newer bot setups use outbound sockets instead, which keeps inbound firewall rules closed.
