I just bought a brand new CP-8841-3PCC-K9 IP phone from an online dealer here in Germany.
When trying to connect the phone to my router fritzbox 7490 I get a starting picture on the phone asking me to "enter activation code". Just that, not "enter activation code or service domain" which would be the ip of my fritzbox.
Where do I get this activation code? Without it, I don't seem to be able to connect the phone to my router.
