Question about Gigaset DL500A (DE version)

Hello Moritz,
I have the following configuration with my customer:
- DL500A on the fixed network
- SL450 HX handset (DECT)
The mobile phone is connected to the DL500A via Bluetooth (next to it) and landline and mobile calls can be received with the Gigaset SL450 HX handset (if required, also via headset with 2.5mm jack).
As the customer is quite sensitive to radiation, this way her head always stays at least 1m or more away from the source of radiation!
I think your plan to access the mobile network via BT with the DL500A will not work!
Greetings & good luck!
