Call quality tips

Ody calls run over the internet from your browser or the iPhone app, so call quality tracks your network — a stable connection, a headset, and an unthrottled path make the biggest difference.

Network

• Prefer a stable connection. Wired ethernet beats Wi-Fi; strong Wi-Fi beats weak Wi-Fi or congested hotspots. On a phone, solid LTE/5G works well.
• Watch for competing traffic. Large uploads, video calls, and streaming on the same connection can starve call audio. Real-time audio needs little bandwidth (~100 kbps) but is sensitive to latency spikes.
• VPNs and strict firewalls can block or throttle the UDP traffic calls use, causing robotic or one-way audio. If quality is poor on a corporate network or VPN, test without it.
• Avoid switching networks mid-call — moving between Wi-Fi networks or from Wi-Fi to cellular can drop the call (see Reconnect after a network change).

Hardware

• Use a headset. It eliminates echo and lets your browser's echo cancellation work less. Built-in laptop mics pick up keyboard and fan noise.
• Pick the right microphone in your browser or OS sound settings if you have several devices connected.
• Close other apps that hold the microphone (video conferencing tools, recording software).

Reading the in-call indicator

The active-call card shows a signal meter with a quality label (e.g. "HD voice · excellent"). If it degrades during a call, the issue is almost always the network path at that moment — move closer to your router or drop the VPN.
