Dear customer,
Thank you for your feedback.
The Ubee EVW3226 requires an RJ 11 cable or adapter.
Now I have yet to order the RJ 11 cable to. Either here at Amazon
if I find them here in the store. Or Google / Bing.
Each other, I recommend at [email protected] towards
Questions whether that also fits in with delivered cable to the device what you have at home.
Ask also your Internet provider to see if your device ISDN capable.
Since at least missing another ISDN adapter or cable in the delivery content.
Addendum:
RJ 11 cable on Amazon purchases. Realized that my name no device
(EVW Ubee 3226) of kabelbw not ISDN capable. Get this device
my relatives.
Since at least missing another ISDN adapter or cable in the delivery content.
