Multi-party-call - How to set up a Conference call

Meetings are the hub of all communication and our ambition is to provide the best sound possible in remote meetings no matter if it’s via a phone line, Wireless Networks, the Internet or systems.

Important to know is that making a conference call is dependent on features provided by the phone service and not by the Konftel itself. On some phone services, conference calls are not allowed at all. Please check with your service provider, reseller or the person that is responsible for communication at your company.

Here is a list of known commands for conference calls with different phone systems.
If you have a system not listed in this table (and you know the command for 3 party calling), please send an e-mail to  .

Konftel 300M

The number of participants you can call is determined by the phone service. There is no limit on the Konftel on how many participants you can call. If you plan to have more than 4 participants in a conference call we suggest that you use a conference bridge service instead.

Konftel 300IP

Konftel 300IP supports a 5-party call (you + four other participants) with the integrated bridge function. To be able to have a 5-party call the service provider (SIP server) must allow the Konftel to have 4 external calls at the same time. Talk with your service provider if you have questions.
