Quick fix
VoIP calls need a steady connection more than a fast one. Run a speed test, plug phones and computers into a cable instead of Wi-Fi, pause big uploads or downloads, and ask your IT team about QoS (call priority) on your router.
Choppy, robotic or delayed audio usually means voice data is arriving late or getting lost on the way. That’s a network problem far more often than a phone problem.
Step by step
Run a speed test
Use our free speed test. Look at upload speed and latency (ping), not just download.
Use a wired connection
Wi-Fi is the most common cause of choppy calls. Plug desk phones and computers into the network with a cable where you can.
Pause heavy traffic
Cloud backups, large uploads, video streaming and software updates can crowd out calls. Schedule them after hours.
Restart the equipment
Restart the modem and router, then the phone.
Check the headset
A failing headset or Bluetooth headset at the edge of its range can sound like a bad connection. Try the handset to compare.
Ask about QoS
Quality of Service (QoS) settings on a business router can give voice traffic priority. Your IT team or provider can set this up.
Consider your internet service
If calls are often poor at busy times, the connection may be too small or unreliable for your team. See business vs. home internet.
