Call audio runs from your headset, through your browser, over your network, to the carrier. Almost every quality problem is in the first half of that path.
The Slow Internet warning
If you see "Your internet is slow, which may cause jitter, lagging in calls, slow loading time, etc.", believe it. In order of effectiveness:
- Plug in an Ethernet cable. Wi-Fi is the single most common cause.
- Stop competing traffic — cloud backups, video calls, large uploads.
- Turn off the VPN for the session. Every hop adds delay.
- Reduce parallel dials. Five lines is five audio streams; a connection that is fine at one dial can fail at five. See Parallel dialing.
Echo
The other side hears themselves. This is almost always laptop speakers plus laptop microphone — the mic picks up the speaker output and sends it back.
Use a wired USB headset. Nothing else reliably fixes it.
Robotic or choppy audio
Packet loss. Same fixes as the Slow Internet warning. If it only happens at certain times of day, it is your network contending with something scheduled — a backup or a shared office link.
Delay, people talking over each other
Latency. Bluetooth headsets add it, VPNs add it, distant Wi-Fi adds it. Go wired.
Calls end by themselves
Check in this order:
- Credits. An account that runs out mid-session drops calls. See Credits and auto-refill.
- Call timeout. If calls end while still ringing, your timeout is short. The options are 20, 30, 40, 45, 60, 90 and 120 seconds.
- Hang up other calls once connected. With parallel dialing on, the other lines are supposed to drop. If reps report calls ending the instant someone answers elsewhere, that is this setting working as designed.
- Network drop. A Wi-Fi roam between access points ends a call instantly.
The other side cannot hear you
Microphone permission or the wrong input device. Check the padlock icon in the address bar, then your system sound settings. Reload after changing either.
Monitoring problems
"SIP client not registered - refreshing page may help" on Salefloor means your own audio client did not register — reload. "Call is still connecting — listening available shortly" just means the call has not been answered yet.
What to send support
Time of the call, the contact's number, the number you dialed from, and which side had the problem. Without the timestamp the call cannot be found.
