We have just moved house and had T-Com switch our existing phone number to the new house. We have ISDN and a Siemens gigaset DECT system. The system worked fine for a couple of days but then stopped working. Telekom say the line is fine and the issue is with our Gigaset. I have removed the Gigaset and just attached a analog phone to the wall and then a wired ISDN phone to the terminal adaptor and the problem does not go away which tells me the problem is not in the Gigaset basestation. We can make outgoing calls so that also tells me the cables are OK.
Any ideas?
