Hi,
I friend gave to me a fixed cordless phone which I'm trying to use on my UPC-Cablecom connection at home.
I can receive calls with no problem, but if I make a call from the phone, it plays a message from Sunrise, telling to contact them to susbcribe to their service.
But this doesn't make sense: my connection is with Cablecom, is it possible the fixed phone it's locked for Sunrise?
I asked Sunrise, Panasonic and Cablecom, all of them tell the problem is of the other, nobody wish to think a bit out-of-the-box maybe because the phone is not new.
Phone model: Panasonic KX-TG110EX

If anyone has an idea of why I can't make calls from the phone, please let me know.
Thanks

It's only a guess, but possibly the Panasonic phone is set up to prefix whatever you dial with a 5 digit code which in principle allows you to select which phone company is to make the call. For example I had so-called preselect with Sunrise, so that normally they handled the call, but I could cause the call to be handled by Econophone using the code 10781. The code for Sunrise is 10707. If your phone is preceding whatever you dial with the 10707 code, this would explain the effect you describe.

The phone came originally along with a contract package from Sunrise. The phones provided with the contracts are locked for Sunrise and the company tells it's not possible to unlock them.

So, I have a "one way" phone.
