Zoom and Teams calls on Starlink

Calls don’t need much speed. They need a line that doesn’t stop, even briefly. Here’s what the call apps ask for, where Starlink falls short, and how to find which part of your setup causes the freezes.

Quick answer

Zoom, Teams and Meet work on Starlink: its typical latency and jitter sit well inside Microsoft’s Teams test limits. The weak spot is short freezes of a second or a few, from obstructions, satellite handovers, Wi-Fi or a busy upload, and most of those can be fixed at home.

Where a video call can break on a satellite connectionA call travels from your computer over Wi-Fi or Ethernet to the router, up from the dish, through a satellite to a ground station, then across the internet to the call service. Problems at home: weak Wi-Fi and uploads filling the line. At the dish: obstructions and satellite handovers about every 15 seconds. Beyond: congestion at busy hours.ComputerRouterDishGround stationCall serviceweak Wi-Fiuploads fillthe lineobstructions,handoversbusy-hourcongestionFix from the left: Ethernet first, then upload limits, then the dish’s view of the sky.
Most call trouble people blame on the satellite starts at the desk (Wi-Fi) or the router (someone uploading). Check those first; they’re the cheapest fixes.

What calls need

Three things decide call quality: latency (how long a packet takes), jitter (how much that delay changes from packet to packet) and packet loss (packets that never arrive). Microsoft’s network test for Teams passes when UDP latency is under 100 ms, jitter under 30 ms and loss under 1% (checked Oct 5, 2026). Those are the pass lines of Microsoft’s test, not a promise that every call above them fails.

Bandwidth matters less than people think. These are the vendors’ own figures for sending your video:

App and call typeVendor figureDirection
Zoom, 1:1 at 720p1.2 MbpsUp and down
Zoom, 1:1 at 1080p3.8 MbpsUp
Zoom, group at 720p2.6 MbpsUp
Teams, 1:1 video (recommended)1500 kbpsUp and down
Google Meet, 720pUp to 1.7 MbpsEach way
Google Meet, 1080pUp to 3.6 MbpsEach way
Webex, 720pAbout 1.5 MbpsPer call

Screen sharing and gallery view add to this. Even so, one person’s call is a small slice of Starlink’s upload. Two people on calls plus a cloud backup is where it gets tight: see two remote workers.

  • Latency: Starlink reports 25.7 ms median peak-hour latency in the US; Ookla measured a 39 ms median in Q1 2026. Both are well under the Teams line.
  • Jitter: Geoff Huston (APNIC) measured an average jitter of 6.7 ms between successive pings. Also well under the line.
  • Loss: Huston measured long-term loss of a little over 1% with one-second pings. That sits right at the Teams pass line, and it isn’t spread evenly: it comes in short bursts. Those bursts are the freezes you notice.

Huston’s measurements aren’t US-specific and aren’t ours. When the owner’s logger has a month of work-hour data, the card below grades it.

Call verdict from the owner’s logger

Logger not started yet

  • Video callsZoom, Teams, Meet, VoIPNot measured yetWhy this rating

    Our measurement: none yet. The owner’s logger hasn’t produced a month of work-day data, so we don’t grade calls.

    Published figures (not ours): Starlink reports 25.7 ms median peak-hour latency in the US; Ookla measured a 39 ms median in Q1 2026. Calls fail on short drops and jitter more than on average latency, which is what the log measures.

    A work-hour minute counts as call-ready when every probe target answered, round-trip latency was at most 100 ms, jitter at most 30 ms and loss at most 1%. OK = at least 99% of work-hour minutes call-ready; Degraded = 95–99%; Would drop = under 95%. Read the guide.

When the logger runs, this card grades one Residential connection at the owner’s home. It will never be a regional average. How we measure.

Why calls freeze for a second or a few

  1. Satellite handovers. The dish switches satellites about every 15 s (Huston). With a clear sky it’s usually invisible. With a partly blocked view, some handovers turn into short gaps.
  2. Obstructions. A tree branch or roof edge in the dish’s view blocks it for a moment as satellites pass. Use the Starlink app’s obstruction check.
  3. Short outages. Network events, weather and software updates cause brief drops. The Starlink app’s Statistics page lists outages while you’re on its router.
  4. Upload saturation. When a backup, photo sync or video upload fills the upload, your call’s packets wait in line behind it. Video freezes, then catches up. How to stop it.
  5. Wi-Fi. Walls, distance, a crowded channel or a laptop roaming between mesh points. It looks exactly like a satellite problem.
  6. Too many connections. CGNAT plans are limited to 1,200 sessions open connections, and Starlink says hitting it can freeze video meetings. Rare in a normal home.

The three-step test: Wi-Fi or the line?

  1. Plug in. Connect the work computer to the router with an Ethernet cable and run calls that way for a day or two. If freezes stop, it was Wi-Fi. (Check your router has a port: The older Gen 2 router has no built-in Ethernet ports; an Ethernet adapter is sold separately.)
  2. Clear the upload. If freezes continue on Ethernet, pause cloud sync, backups and uploads on every device during a test call. If freezes stop, it’s upload saturation.
  3. Match the times. If they still happen, write down the time of each freeze and compare it with outages on the Starlink app’s Statistics page. Matches mean the line: check obstructions first, then plan a backup.

Fixes, cheapest first

  1. Use the desktop app and close other video. Free. Browsers and streaming tabs compete for the same line.
  2. Pause sync during calls. Free. OneDrive, Dropbox, Google Drive, iCloud and phone photo backup all have a pause.
  3. Run Ethernet to your desk. The price of a cable. Removes Wi-Fi from the list.
  4. Set an upload limit on your own router (smart queue management, SQM). Your calls stay clean even when someone uploads. Needs a router that supports it.
  5. Clear the dish’s view. Use the Starlink app’s obstruction check; moving the dish or trimming a branch can remove a whole class of freezes.
  6. Add a backup line with automatic failover. It won’t stop a one-second blip, but it keeps a long outage from ending your call. Failover Builder.
  7. Consider network priority. Starlink says users on the lower Residential tiers are more likely to slow down at busy times than Residential Max users, the highest-priority Residential plan (checked Oct 5, 2026). This helps with evening congestion, not with obstructions.
IT For your IT person: call media on Starlink
  • IPv4 CGNAT on Residential; Teams, Zoom, Meet and Webex media go outbound over UDP and work behind it. Session limit 1,200 sessions per line.
  • Expect brief loss bursts around satellite handovers (about every 15 s) when the dish’s field of view is partly blocked.
  • Split-tunnel call media around the corporate VPN where policy allows; it shortens the path and survives VPN reconnects.
  • SQM (CAKE or fq_codel) with an upload shaper slightly under the line’s floor fixes bufferbloat-driven freezes. Needs a third-party router (Starlink router in bypass mode).

When this is the wrong choice

  • Customer-facing calls all day, no backup line. Short freezes will land in front of customers. Add a backup, or use fiber or cable if it reaches you.
  • Blaming the satellite before plugging in. Run the three-step test first; Wi-Fi is the cheapest fix.
  • Buying more download speed to fix freezing calls. Calls use little bandwidth; freezes come from gaps, not speed.

Questions people ask

Does Zoom work on Starlink?

Yes. Zoom says 1:1 720p video uses about 1.2 Mbps each way (checked Oct 5, 2026), far below Starlink’s upload. What hurts calls is short freezes from outages, obstructions, Wi-Fi or a busy upload, not bandwidth.

Does Microsoft Teams work on Starlink?

Usually. Microsoft’s network test passes Teams when UDP latency is under 100 ms, jitter under 30 ms and loss under 1%. Starlink’s typical latency and jitter are well inside those; short bursts of loss are the weak spot.

Why does my call freeze for a few seconds and then catch up?

A short gap in the connection: a satellite handover with a blocked view, a moment of obstruction, someone uploading, or weak Wi-Fi. The three-step test on this page tells you which.

Should I turn off my camera to make calls steadier?

It helps when the problem is upload: video is most of what you send, while Teams audio needs about 58 kbps. It won’t help with outages, which cut audio too.

Is a VPN making my calls worse?

It can. If call traffic goes through the company VPN, every packet takes a longer path and suffers when the VPN reconnects. Ask IT whether Teams or Zoom traffic can skip the VPN (split tunnel).
