We just got connected with Snap UFB today, as the 3rd and final installation occured this morning. I am using the Fritz Box 7360 as well as the Fritz Fon on a 30/10 connection, and the technition said that we were all ready to go as he left. However after connecting the Fritz Fon , our calls still go to our old phone that is connected through copper on our telecom connection that we are going to terminate. Will the calls go to the Fritz Fon after we cancel our copper service, or do I have to just wait a few days for Snap to configure everything accordingly?

Cheers for the Help in advance!
