Frequently asked questions about telephony

Ready answers for common situations. If the solution did not help, contact support.

Check the headset microphone or the device’s built-in microphone. Make sure the correct input device is selected in the softphone settings and that sound is not muted. Check the microphone volume level and make sure the cable is not physically damaged.

Make sure the speakers or headphones are working and selected as the output device in the application. Check the volume in the system and in the softphone itself. If there are issues with one-way audio, restarting the device often helps.

Check your balance, service status, and whether the number is dialed correctly, including the country and operator code. Make sure the SIP account is registered and the internet connection is stable.

Check the login, password, and SIP server address. Make sure you are using the current details from your personal account and that the firewall or router is not blocking SIP traffic.

Poor quality is most often caused by an unstable internet connection, Wi-Fi interference, or an overloaded channel. Connect via cable, check speed and ping, and disable VPN if possible.

The cause is usually packet loss in the network. Check the connection quality, restart the router, and if you are using mobile internet, change the connection point.

Check the forwarding rules in your personal account or the virtual PBX scenario. Make sure the number to which the call is forwarded is active and available.

Check the SIP account registration, incoming call routing settings, and number status. Also check whether Do Not Disturb mode is enabled.

Correct Caller ID display depends on the operator and device settings. Make sure number display is enabled in the SIP account and that the device supports Caller ID reception.
