As these DECT 6.0 systems are supposed to be compatible, does anyone
know if it is possible to register an AT&T Dect 6.0 base station with
Panasonic Dect 6.0 handset please? If possible without jerry-rigging
two wires between the two contacts on the base station and the two
contacts on the handset for the registration process?

No. In order to support interoperability among a mix of vendors, the
handset must support GAP (Generic Access Profile):

This is widely supported in Europe, but not in the US. However, even
if GAP were supported, there is not test or certification requirement
for cross vendor interoperability. The GAP spec also does not cover
optional features, such as answering machines. If the base has an
answering machine, it's unlikely that another vendors handset can
program the answering machine as the menus are in the handset, not the
base.
