If a German participant is invited by you for your conference call, he or she will call the German dial-in number 01803 - 127127. This is a German number. He or she does not need to call +49 1803 127127 or + 44 1803 127 127 because you are organizing the conference call. If the participant from Germany is a UK person who calls on his or her mobile phone, he/she should use the worldwide dial-in number: +44 843 373 0999.

The Conference Call

What can I do if a participant calls in from a noisy environment?

Ask the participant to find a quiet environment to mute the background noise. If this is not possible, you can ask the participant to key in # 6 to temporarily switch off the microphone. To reactivate the microphone, the participant again dials # 6. Do not use the mute button on your phone, this may cause the call to get disconnected.

What can I do if an echo is heard during the conference call?

This is usually caused by a participant who has put his / her phone on the speaker or 'hands-free'. Another common cause is a participant dialing in from the car with a Bluetooth 'hands-free kit'. If the sound of the speaker is too loud, the microphone picks up this sound signal and sends it back in the conference call.

Ask the participant to take the phone off the speaker or turn the volume down. If this is not possible, you can ask the participant to key in # 6 to temporarily switch off the microphone. To reactivate the microphone, the participant again dials # 6.

Can I pay the costs for all participants?

Yes, please have at our solution on this page. You can use your pincode but you have to use different dial-in numbers.

Can I pre-program my phone?

Yes, with you can preprogram your phone.
