LinkedIn X [Back to blog](https://skipcall.io/en/blog) VoIP Published 19 October 2026 # Does VoIP Work Over Starlink? Latency, Jitter and Setup Yes, VoIP works over Starlink: published latency of 25 to 60 ms sits far inside the voice budget. The catch is consistency, not speed. Satellite handovers every 15 seconds, a narrow upload lane and queue buildup on the Starlink router produce choppy calls, and each has a fix. Real numbers, the right plan for a team, router setup and a troubleshooting flow. 25.7 ms SpaceX's reported US peak-hour median latency in 2025, against a 150 ms one-way voice budget 6.7 ms average jitter APNIC measured on an idle Starlink link, under the 30 ms guideline 15 s between satellite reconfigurations, the source of the short loss bursts a jitter buffer must absorb Yes. VoIP works over Starlink: Starlink publishes a 25 to 60 ms latency range for its US plans, and SpaceX reported a 25.7 ms median peak-hour latency for US customers in 2025, far inside the 150 ms one-way budget in ITU-T G.114. The catch is consistency rather than speed. Satellite handovers every 15 seconds, a narrow upload lane and queue buildup on the Starlink router produce choppy calls, and each has a fix. This article covers only the satellite-specific questions. For bandwidth planning and the rollout checklist, see our guide to [business VoIP requirements](https://skipcall.io/en/blog/business-voip-phone-service). ## Why Starlink latency is so much lower than older satellite internet Geostationary satellites (HughesNet, Viasat) sit at 35,786 km above the equator. Propagation alone takes 238 to 284 ms for the trip up to the satellite and back down to the ground, so about half a second for a full round trip, and with encoding and ground-segment delays an IP round trip of around 660 ms is common. That exceeds the 400 ms one-way ceiling ITU-T G.114 sets for network planning. Starlink satellites orbit at roughly 550 km (newer V2 shells sit at 525 to 535 km). At that altitude the up-and-back trip is about 3.7 ms, and the minimum propagation round trip through a satellite to a ground station works out to roughly 7.4 to 15 ms depending on elevation. Add scheduling, the ground network and the hop to the nearest point of presence, and observed minimums land around 20 ms, with a global median of 40 to 50 ms in independent measurements. SpaceX’s 2025 network update reported a 25.7 ms US peak-hour median. Figure 1: Altitude decides the latency floor: a 550 km orbit versus a 35,786 km orbit. Sources: APNIC Labs, Starlink consumer information sheets, ITU-T G.114. ## What real Starlink latency, jitter and packet loss numbers look like **Latency.** Starlink’s US consumer information sheets list 25 to 60 ms for Residential and Priority plans and “under 99 ms” for Roam. Ookla’s state-level data for the second half of 2025 shows ten states with median multi-server latency under 40 ms; the best sat at 37 ms. **Jitter.** This is the number that matters most for voice and the one Starlink does not publish. Geoff Huston’s APNIC analysis measured an average jitter of 6.7 ms between successive round-trip samples on an idle link. The same work saw handover spikes adding roughly 30 to 50 ms, with a worst case jump from 30 to 80 ms. APNIC’s NANOG 93 presentation describes handovers adding “very short-term additional queuing latency of about 80 to 100 ms”. **Packet loss.** APNIC’s 1-second paced pings found a long-term average loss a little over 1 percent, in a 1 to 2 percent range unrelated to congestion. The NANOG material puts “micro-loss” at about 1.4 percent, mostly from handover events. **Upload.** Ookla’s 2025 Global Satellite Broadband Performance Report put the US median upload at 16.91 Mbps (download 117.74 Mbps); a separate Ookla H2 2025 cut reported 19.3 Mbps up and 133.8 Mbps down. Metric #### Latency - **Industry threshold for voice** : 150 ms one-way or less (ITU-T G.114, Cisco); Teams client target under 50 ms one-way, under 100 ms RTT - **Verified Starlink measurement** : 25 to 60 ms published; 25.7 ms US peak-hour median (SpaceX, 2025); 37 ms best-state median (Ookla, 2H 2025). Starlink quotes round-trip figures, so the one-way value is lower still - **Verdict** : Pass with a wide margin Metric #### Jitter - **Industry threshold for voice** : Under 30 ms average (Cisco); under 30 ms in any 15 s interval (Teams client) - **Verified Starlink measurement** : 6.7 ms average; 30 to 50 ms spikes at handovers (APNIC) - **Verdict** : Pass on average, borderline during handover bursts Metric #### Packet loss - **Industry threshold for voice** : 1 percent or less (Cisco); under 1 percent in any 15 s interval (Teams client) - **Verified Starlink measurement** : About 1 to 2 percent long-term, mostly at handovers (APNIC); about 1.4 percent micro-loss (NANOG 93) - **Verdict** : Borderline; codec concealment and FEC matter Metric #### Upload bandwidth per call - **Industry threshold for voice** : 21 to 320 kbps (Cisco); 58 kbps recommended (Teams); 60 to 80 kbps (Zoom audio) - **Verified Starlink measurement** : 16.91 to 19.3 Mbps median upload (Ookla, 2025) - **Verdict** : Pass, as long as nothing else saturates the uplink Latency is a non-issue and average jitter is excellent. What can hurt a call is short loss bursts at handovers and jitter caused by your own traffic filling the uplink. Figure 2: Thresholds versus measurements. Thresholds from ITU-T G.114, Cisco and Microsoft; measurements from SpaceX (2025), Ookla (2H 2025) and APNIC Labs. Loss is the one metric where Starlink sits at or just above the guideline. ## Why Starlink switches satellites every 15 seconds, and what it does to a call A Starlink satellite travels at about 27,000 km/h and crosses your dish’s field of view in minutes, so the terminal must keep changing satellites. The scheduler assigns satellites in 15-second slots, globally synchronized, so every terminal reconfigures at the same instants. FCC filings quoted in the 2023 paper “A Multifaceted Look at Starlink Performance” and APNIC’s measurements both show it. For a voice stream sending a packet every 20 ms, a reconfiguration means a handful of packets arrive late or not at all and round-trip time jumps for a fraction of a second, then settles until the next boundary. Three mechanisms absorb this. **The jitter buffer.** Every client holds incoming audio briefly before playing it, so a packet that arrives 40 ms late still plays in order. Every millisecond of buffer is a millisecond of added mouth-to-ear delay. A 60 ms buffer on a 40 ms link gives roughly 100 ms one-way, still under the G.114 guideline. Adaptive buffers grow with variation and shrink when the link is calm; on Starlink they settle slightly larger than on fiber. **Packet loss concealment and forward error correction.** Opus, the codec in WebRTC softphones, Teams and most cloud phone systems, scales from 6 to 510 kbps and includes in-band FEC: perceptually important frames are re-encoded at a lower bitrate and tucked into the following packet, so a single lost packet can be rebuilt from the next one. The Multifaceted paper observed Zoom sending more FEC traffic over Starlink than over wired links for this reason. G.711 at 64 kbps and G.729 at 8 kbps, the codecs on most SIP desk phones, have simpler concealment. **Short duration.** A sub-second disturbance every 15 seconds means the link is clean more than 95 percent of the time. What is audible is a disturbance landing on a queue that is already full, which brings us to the uplink. ## Why upload is the real constraint for Starlink voice calls A single audio call is tiny: Cisco puts one at 21 to 320 kbps depending on codec; Teams recommends 58 kbps; Zoom lists 60 to 80 kbps. Against 17 to 19 Mbps of median upload you could in theory run a hundred calls. But voice is symmetric and everything else is not: a screen share, a cloud backup, a security camera or a colleague’s 1080p video call (3.8 Mbps up on Zoom) all compete for the same upstream lane, and when it fills, packets queue. **Bufferbloat on the Starlink terminal.** Bufferbloat is high latency that appears when other traffic is on the network, caused by excessive buffering in the modem. The Multifaceted paper measured Starlink round-trip times rising two to four times, to roughly 400 to 500 ms, during bulk downloads, and APNIC attributes handover spikes to “deep buffers” in the user terminal. The fix is Smart Queue Management: a router that keeps its own queue short and feeds the terminal slightly slower than it can forward, so the deep buffer never fills. The bufferbloat.net guidance: measure the real link speed, enable SQM (cake or fq_codel) at those values, then adjust until loaded latency stays within 15 to 25 ms of idle. > Against 17 to 19 Mbps of median upload you could in theory run a hundred calls. One cloud backup is enough to make every one of them stutter. ## Which Starlink plan a business should use for VoIP What differs between plans is priority during congestion, upload range, IP addressing and mobility. Prices are from Starlink’s published US consumer information sheets and service-plan document. SpaceX raised several consumer prices by $5 to $10 per month in May 2026, so confirm at checkout. Plan #### Residential - **Published price (US)** : $120 to $139 per month on sheets (plus 2026 increase) - **Data priority** : Unlimited Standard data; below Priority during congestion - **Published performance** : 150 to 350 Mbps down, 20 to 40 Mbps up, 25 to 60 ms - **Fit for business voice** : Good for a home office with one or two callers. CGNAT, no public IP. Plan #### Residential Lite - **Published price (US)** : $80 per month (2025 listing) - **Data priority** : Unlimited, deprioritized below Residential - **Published performance** : Not separately published - **Fit for business voice** : Cheapest; peak-hour deprioritization makes it the least predictable for calls. Plan #### Priority / Local Priority (Business) - **Published price (US)** : From $65 per month for 50 GB; sheets list $176 (40 GB), $374 (1 TB), $748 (2 TB); overage $0.74 per GB - **Data priority** : Priority data outranks Standard and Mobile users, then unlimited Standard - **Published performance** : 120 to 270 Mbps down, 12 to 35 Mbps up, 25 to 60 ms, availability expected at 99 percent or more - **Fit for business voice** : Best fit for an office with several concurrent calls. Public IPv4 available. Plan #### Global Priority (Business) - **Published price (US)** : $250 to $2,150 per month for 50 GB to 2 TB (2025 listing) - **Data priority** : Priority, usable in motion and at sea - **Published performance** : Not separately published - **Fit for business voice** : Vehicles, vessels, multi-country teams. Plan #### Roam 50 GB / Roam Unlimited - **Published price (US)** : $80 and $195 per month on sheets (plus 2026 increase); Mini kit $599 - **Data priority** : Mobile data; ranks below Standard - **Published performance** : 30 to 100 Mbps down, 10 to 30 Mbps up, under 99 ms - **Fit for business voice** : Workable for a traveling rep on a Mini. Lowest priority tier. **Priority is about congestion, not speed.** Starlink’s service-plan document states that Priority and Mobile Priority users take precedence over Standard, and Standard over Mobile, and that higher-priority users “see faster, more consistent speeds during peak use”. If your team calls in the evening, when residential cells are busiest, Priority data is the difference between predictable and unpredictable jitter. **A public IP removes a class of SIP problems.** Most Starlink plans sit behind carrier-grade NAT (CGNAT), and the stock router cannot forward ports. Priority plans let you enable a public IPv4 from the business dashboard; it is dynamic but tends to stay stable for long periods. **Priority data runs out.** Voice itself uses little (a G.711 call at 64 kbps per direction is about 29 MB per hour each way, before packet overhead), but once the allowance is consumed the plan falls to Standard priority or bills $0.74 per GB. Size the allowance for the site’s total traffic, not for the calls. ### Does Starlink Mini work for VoIP? Yes, with expectations set correctly. The Mini is a 1.1 kg flat panel with Wi-Fi 5 (802.11ac), a built-in router, a 110-degree field of view and a 25 to 40 W draw. Starlink’s Roam sheet lists the Mini kit at $599 and Roam performance of 30 to 100 Mbps down, 10 to 30 Mbps up, latency under 99 ms. For a field rep making one call at a time, that is plenty. The constraints: Roam is the lowest priority tier, the service may not be used while the dish is in motion, and the wired port needs the Starlink Plug accessory. ## How to configure the network for VoIP over Starlink Figure 3: The Starlink router in bypass mode hands routing, queue management and QoS to a router you control. Desk phones are wired; softphones on laptops use Wi-Fi. 01 #### Put the Starlink router in bypass mode and use your own router Bypass mode disables the Starlink router’s Wi-Fi and routing and passes the connection straight to a third-party router. Enable it in the Starlink app under Settings (or in the web portal under Manage); it is reversed only by a factory reset (power-cycle six times on Gen 2, hold reset for 10 seconds on Gen 3). Gen 2 kits need the Ethernet adapter; Gen 3 has built-in Ethernet. Bypass removes double NAT and is the only way to run SQM, DSCP-aware queuing or port forwarding. Routers running OpenWrt, Asuswrt-Merlin or DD-WRT, or a Ubiquiti EdgeRouter, can do the next step. 02 #### Enable SQM (cake or fq_codel) on the WAN interface Start from measured speeds and test with a latency-under-load tool. Because capacity shifts with every 15-second slot, a fixed shaping rate is a compromise; cake-autorate, which bufferbloat.net lists specifically for Starlink, adjusts the rate continuously. Tune the upload direction carefully; it fills first. 03 #### Mark voice with DSCP EF (46) and honor it Cisco’s QoS baseline, following RFC 3246, marks voice as DSCP EF (46) so routers can place it in a strict-priority queue. Most SIP phones do this by default. The marking means nothing on the public internet, but at the shaping point on your router it guarantees a voice packet never waits behind a file upload. 04 #### Wire the desk phones Wi-Fi retransmissions and contention stack on top of handover jitter, so desk phones and conference-room hardware belong on Ethernet. Softphone laptops should sit on 5 GHz close to the access point. 05 #### Handle NAT for SIP correctly SIP signaling carries IP addresses inside the message body, and behind CGNAT neither your router nor your PBX knows the public address. Cloud phone systems and WebRTC softphones solve this with STUN (to discover the public mapping) and TURN (a relay both sides can reach when direct media fails), and they work on Residential Starlink without configuration. Self-hosted PBXs and SIP trunks are different: without a public IP you must register outbound to the trunk provider, run the PBX in the cloud, or move to a Priority plan and enable the public IPv4. If you are evaluating [SIP trunking](https://skipcall.io/en/blog/sip-trunking) for a Starlink site, ask about the public IP first. Also disable SIP ALG on your router; it causes more one-way-audio problems than it solves. 06 #### Keep the uplink budget honest With 17 to 19 Mbps of median upload, five Zoom 1080p video calls would consume it all; five audio calls would use about 0.4 Mbps. ## How to troubleshoot choppy calls on Starlink **Step 1: Read the Starlink app statistics.** Open the app, tap the network card, then Statistics (or Advanced). Latency should sit in the 25 to 60 ms band and, more importantly, stay flat. Ping drop rate should be under 1 percent; anything above that is audible. The obstruction map needs 6 to 12 hours of satellite passes to populate, so leave the dish in place for a day before judging it. **Step 2: Fix obstructions before anything else.** Under 1 percent obstruction is the target for calls; 0.5 to 2 percent can still interrupt them; above 5 percent, move the dish. **Step 3: Run a continuous ping from a wired machine.** Ping a stable target (your provider’s SIP server or a public resolver) once per second for ten minutes with no other traffic. Then repeat while uploading a large file. If latency jumps into the hundreds of milliseconds under load, you have bufferbloat: lower the upload shaping rate until loaded ping stays within about 25 ms of idle. **Step 4: Check the call-quality metrics your phone system already collects.** Cloud phone systems, Teams and Zoom report per-call jitter, loss, RTT and a MOS estimate. MOS is the 1 (bad) to 5 (excellent) listening-quality scale; ITU reference values put G.711 at 4.1 and G.729 at 3.92, so a call near 4.0 is as good as the codec allows. MOS that drops only during large uploads is queuing; only at certain hours is congestion (a Priority plan is the lever); only on Wi-Fi softphones is the wireless link. **Step 5: Compare codecs and buffer settings.** Switch softphones from G.729 to Opus if you can; its in-band FEC is built for short, bursty loss. If a desk phone exposes its jitter buffer, set it to adaptive with a maximum around 80 to 100 ms, which covers the handover spikes APNIC measured while keeping one-way delay under 150 ms. **Step 6: Rule out double NAT and SIP ALG.** One-way audio, calls that drop shortly after answer, or phones that register and then go silent are NAT symptoms, not satellite symptoms. Confirm bypass mode is actually on (your router’s WAN interface should hold the address Starlink assigns, not a private address from the Starlink router) and that SIP ALG is off. ## Sources - [Starlink says SpaceX targeting 2026 for launch of Starship-ready terabit satellites (The Register, reporting the Starlink 2025 network update)](https://www.theregister.com/2025/07/16/starlink_network_update/) - [Starlink Residential Consumer Information Sheet (PDF)](https://starlink.com/public-files/CIS_Residential_March2025.pdf) - [Starlink Priority Consumer Information Sheet (PDF)](https://www.starlink.com/public-files/CIS_Priority_March2025.pdf) - [Starlink Roam Consumer Information Sheet (PDF)](https://www.starlink.com/public-files/CIS_Roam_March2025.pdf) - [Starlink Service Plans (PDF)](https://api.starlink.com/public-files/Starlink%20Service%20Plans.pdf) - [Starlink median U.S. speeds still short of federal minimums: Ookla report (Telecompetitor)](https://www.telecompetitor.com/starlink-median-u-s-speeds-still-short-of-federal-minimums-ookla-report/) - [Starlink nearing full FCC broadband compliance: Ookla report (Telecompetitor)](https://www.telecompetitor.com/starlink-nearing-full-fcc-broadband-compliance-ookla-report/) - [Starlink Hits New Highs in the US (Benton Institute summary of Ookla)](https://www.benton.org/headlines/starlink-hits-new-highs-us) - [Starlink broadband speeds increase in 2025, but they’re still not great (Fierce Network)](https://www.fierce-network.com/broadband/starlink-broadband-speeds-increase-2025-theyre-still-not-great) - [Starlink Price Increase: Monthly Plans Rise $5-$10 (5Gstore)](https://5gstore.com/blog/2026/05/16/starlink-price-increase-monthly-plans/) - [Here’s How Much Starlink Will Cost You (SlashGear)](https://www.slashgear.com/1922184/how-much-does-starlink-cost/) - [Starlink Bypass Mode Explained (Yahoo Tech / BGR)](https://tech.yahoo.com/computing/articles/starlink-bypass-mode-explained-141700740.html) - [Guide: Starlink Port Forwarding and Workarounds (DishyTech)](https://www.dishytech.com/does-starlink-have-port-forwarding/) - [Starlink app guide (SatSpeedCheck)](https://satspeedcheck.com/blog/starlink-app-guide/) - [A Transport Protocol’s View of Starlink (Geoff Huston, APNIC ISP Column, May 2024)](https://ispcol.potaroo.net/2024-05/starlink-tcp.html) - [Starlink presentation at NANOG 93 (APNIC Labs, February 2025, PDF)](https://labs.apnic.net/presentations/store/2025-02-04-starlink-nanog93.pdf) - [A Multifaceted Look at Starlink Performance (arXiv 2310.09242)](https://arxiv.org/pdf/2310.09242) - [ITU-T Recommendation G.114: One-way transmission time (PDF)](https://www.cs.columbia.edu/%7Eandreaf/new/documents/other/T-REC-G.114-200305.pdf) - [Cisco Press: QoS Requirements of Voice](https://www.ciscopress.com/articles/article.asp?p=357102) - [Understand Teams network requirements (Microsoft Learn)](https://learn.microsoft.com/en-us/training/modules/plan-optimize-network-performance-for-teams-phone-system/2-understand-teams-network-requirements) - [Zoom Video SDK system requirements (bandwidth table)](https://developers.zoom.us/docs/video-sdk/system-requirements/) - [RFC 6716: Definition of the Opus Audio Codec](https://www.rfc-editor.org/rfc/rfc6716) - [Voice Codecs: G.711, G.729 and Opus in Practice (SIPPulse)](https://sippulse.com/en/blog/codecs-voz-g711-g729-opus) - [What’s toll-quality voice?

Starlink publishes 25 to 60 ms for US Residential and Priority plans, and SpaceX reported a 25.7 ms US peak-hour median in 2025. The ITU-T G.114 guideline for transparent interactivity is 150 ms one-way, so even with a generous jitter buffer a Starlink call stays inside the budget. **How much jitter does Starlink have?** Starlink does not publish jitter. Independent APNIC measurements found an average of 6.7 ms between successive samples on an idle link, well under the 30 ms guideline Cisco and Microsoft use. The exceptions are brief spikes of 30 to 50 ms (sometimes 80 to 100 ms of short-term queuing) at the 15-second reconfiguration boundaries; jitter buffers absorb these. **Does Starlink drop packets on calls?** Some. APNIC's long-term measurement found loss a little over 1 percent, mostly single packets at handover events, and NANOG 93 material puts micro-loss at about 1.4 percent. That is at or just above the 1 percent guideline. Opus with forward error correction conceals it well. **Which Starlink plan is best for a business phone system?** For an office with several simultaneous calls, a Priority (Local Priority) plan. Priority data outranks Residential and Roam traffic during congestion, the sheets list 99 percent or better expected availability, and the business dashboard lets you enable a public IPv4, which simplifies SIP trunks and self-hosted PBXs. **Can I use Microsoft Teams or Zoom calling over Starlink?** Yes. Teams' client-side targets are under 100 ms round trip, under 30 ms jitter and under 1 percent loss in any 15-second window; Zoom needs 60 to 80 kbps for audio. Typical Starlink figures meet the latency and jitter targets and sit near the loss target. Budget the upload for video and screen sharing. **Does Starlink Mini work for softphone calls?** Yes, for one user at a time. The Mini runs on Roam plans with a published 30 to 100 Mbps down, 10 to 30 Mbps up and under 99 ms latency, which is more than a single Opus or G.711 call needs. It is the lowest data-priority tier, and the dish must be stationary during use. **Do I need bypass mode for VoIP on Starlink?** Not for a single softphone on a laptop, which works on the stock router. You do need it as soon as you want Smart Queue Management against bufferbloat, DSCP-based prioritization, port forwarding or a stable NAT for SIP desk phones. It is reversed only by factory-resetting the Starlink router, so plan the change.
