Welcome to the Community @ojhap.

I have just activated the conference function for your phone number, which is registered here in the community.

Best regards

Steffen

Hi @o2_Steffen I have taken another contract from O2. Please help to activate conference service on my new contract as well.

Good evening @ojhap 
It's great that you've contacted us again 
I've now activated the connection for your new contract and confirmed it by text message.

Have fun on the phone 
Best regards, Kathi
