I Can't Hear The Caller

• Ensure your computer volume is turned up to a sensible level and not muted either on your computer or on any external device.
• Check connections of any headset or speakers you are using.
• Check the Audio Output setting in the Circuit settings, select the correct output for the setup you are using, i.e if you’re using a USB headset, ensure this is selected here. Default Audio Output will use the audio device specified in your system audio settings.

The Caller Can't Hear Me

• Check that the correct microphone is selected in the Audio/Video settings.
• Check your microphone is connected correctly to the microphone port on your computer.
• Ensure your microphone is working properly by checking your system sound settings.

I Can’t Hear the Ringtone

• Ensure your computer volume is turned up to a sensible level and not muted either on your computer or on any external device.
• Check the Circuit settings for Ringing Output. This should be set to an output that you will always be able to hear.

I Can’t See The Caller

• If you are able to communicate with the caller, ask them to check their camera is enabled.
• Ask the caller to check their settings and ensure their intended camera is selected.
• Ask the caller to check if any other application on their system is using the camera and close if necessary.

The Caller Can't See Me

• Ensure that the camera is enabled.
• Check your webcam is plugged in correctly and re-connect if necessary.
• Check your Circuit Audio/Video settings and ensure the correct camera is selected.
• Ensure your webcam isn’t being used by any other applications currently running on your system and exit any applications that are using the camera.

The Timer Isn't Working

• This is a known bug within Circuit Desktop App. It has been reported and should be fixed in a future software update.

The Start of a Call is Unstable

• This is a known issue within Circuit. It is sensible to wait a few seconds for the connection to stabilise before commencing a conversation.

Move Calls Between Devices
An active call can be transferred between your desktop app and a smartphone that has the Circuit app installed. To do this you'll need to pull the call to the new device by swiping "Pull" on a phone or clicking the "Pull" button on the desktop app.

Pushing a Call to an Alternative Number
The push function will push an active call to an alternative number as specified in the settings.

Use Standard Phone Commands
You can use standard phone keypad commands as if you were sat at your desk. For example:

• 9 for an outside line
• *49 to withhold your number
• 1010 for voicemail

Hold
When placing a call on hold, this is not always clear from the other end as there is no hold music or tone. Tell the caller you are placing them on hold and the line will go quiet.

Call Forwarding
Call forwarding can be setup on the Circuit Desktop App in the same way as you would on your desk based handset. See the link below 'Unified Communications VOIP Guide' for all call forwarding commands.

Using Multiple Web Conferencing Applications

If you are using more than one web conference application in your work (i.e Zoom / Circuit / Google Meet / Skype) you may find that you have issues getting an application to detect your webcam. It is usually necessary to stop the video in one application before you can start it in another. In some cases, it will be necessary to exit all but the one application you are currently using. In extreme cases, you may have to restart your system to release the webcam. The above describes how a Windows computer usually behaves. If you are using a Mac you may find that different applications will happily share the webcam stream.

Audio is usually shared between multiple applications without any issues.
