"This language is not pre-installed in the device. To load this language, the device must be connected to the Internet."
what but thanks to internet worked directly. Have Followed the SIP accounts created and registered a handset that works, both incoming and outgoing calls function. Even a firmware update and that was it, I thought. The update was done, only the language can now no longer on "German" switch, which is probably always necessary and can not be change by default. Now appears after downloading
"Transmission error 503!
It is not possible to change the language as the language file can not be downloaded from the Gigaset server. For Further Information please consult the user guide. "
A restart etc. changed thereto not something I anschrieb the Service Gigaset and alleging the error. He answered after 2 days, excerpt:
"Unfortunately, we can in this case does not help directly. The Gigaset pro series is a very special company division. For this reason we have here has no information about those devices.
Please contact to your dealer or to the service you announced. The PIN number for the service hotline you received if you are self-registered dealer for Pro devices. Otherwise, we need to refer to your dealer where you purchased the device.

For these time-wasting detour I have no sympathy, "Pro" I define different. One star deduction for and one for the error. The function of the box is otherwise well.
