Use this checklist when audio is one-way, the call drops, keypad tones fail, or a support line cannot hear you clearly.

Fast checkNo one can hear me

Check browser microphone permission, selected input, headset mute, and VPN before redialing.

Steps before you call

Allow microphone access in the browser and test the input device.
Turn off VPN or captive Wi-Fi filters if the call cannot connect.
Retry from a quieter network and keep the keypad visible for phone-tree prompts.

Practical tips

Headphones often fix echo and noisy hotel-room calls.
Refresh the page after changing microphone permissions.
If one toll-free number fails, try the company’s direct local support number.

Useful official sources

Use official pages for sensitive calls, especially banking, tax, immigration, airline, insurance, or identity questions.
