After the change over I was afraid we’d lost the electronic answering machine that we’d been using whilst connected to T-elekom, but I was wrong. Arcor has unified messaging including an answering machine with its own telephone number. I’m not quite sure how reliable it is: during the first five tests I get an voice message telling me that the call isn’t possible at this moment ( die von Ihnen gewünschte Verbindung mit diesem Dienst oder Dienstmerkmal ist nicht möglich) But the hyper-cool bit about it, when it does work? I get the call relayed to my e-mail account with the voice recording attached as a .wav file.
