Occasionally, you may want to make a second call on your smartphone while you already have an active connection on your laptop using your number.

Outgoing calls are possible, incoming calls only if the second call (call waiting) has been enabled in the telephone system (second call is disabled by default). The second call must be set or removed individually for each device type (PC, Apple IOS smartphone, Android smartphone). To do this, please contact the Service Desk for this.
