PowerDialer places calls from your browser. That makes setup easy and makes your local environment part of the call path.
Browser
Use a current Chrome or another Chromium browser (Edge, Brave, Arc). The Chrome extension, which lets you dial from any web page, is Chrome-only.
Do not run two dialing sessions in two tabs. The dialer holds one audio device and one session; a second tab fights it for both.
Microphone permission
The browser will ask for microphone access the first time you dial. If you refuse it, calls connect but the other side hears nothing. Re-enable it from the padlock icon in the address bar, then reload the page.
Headset
Use a wired USB headset. Laptop speakers plus a laptop microphone cause echo that the other side hears, and echo makes people hang up. Bluetooth adds latency and drops under load.
Network
The dialer watches your connection and shows a Slow Internet warning when it degrades: "Your internet is slow, which may cause jitter, lagging in calls, slow loading time, etc."
If you see it:
- Move to wired Ethernet, or closer to the access point.
- Stop other uploads — backups, video calls, large syncs.
- Avoid VPNs during a session. They add a hop to every audio packet.
Parallel dialing multiplies this. Five simultaneous calls is five audio streams; a connection that is fine at one dial can fall apart at five.
Seat and permission
Dialing is gated on your organisation's plan and on your seat. If the dialer is greyed out or you see a no-seat message, an admin needs to assign you one from Subscription → Seats. See Plans, seats and team members.
