Hello together,

after I hope now already since a few days rather unsuccessfully Internet through forest, I now that someone me here can help.
I use CO2 with the Fritz box 7170 since approx. nem half year. The configuration have I at that time in such a way made, how it also, also everything stands here marvelously functioned.
Use (deactivated, PVC deactivated, all four Internet call numbers registered to fixed net and also the hooks with number for registration)

For Friday now suddenly the telephone does not go any longer, without I would have rumgefuhrwerkt at the attitudes. (Internet runs further perfectly!) If someone calls here, the same is constantly occupied with the attempt to telephone after outside.
Fritz box announced type (415) as error “unsupported media” and/or. from time to time times meant that the registration with the telephone number failed.

Thereupon I tried to enter everything again again (all call numbers deleted and again again entered). Further wear ich's with PVC and/or. out, CLIR tries out and/or. on, telephone rausgeschmissen and again furnished,… So quite everything that occurred to me.
Brought that everything nothing at all, except from time to time a beep clay/tone before the busy signal with the Raustelefonieren.

Next I the Fritz box clamped and the UFO again to, because I wanted to look whether something in the attitudes one changed. Those were however all like before (inclusive user names and password), to telephone go with the UFO unfortunately also. (Unfortunately, because thereby with me hope smashed itself that I by means of the Hotline which reach could…)

When I then the Fritz box again in enterprise took, still Internet functions, however those says to me now that no calls were led. (Tests unite defiance)
The only message, which I now got, was “Internet connection (Telefonie) successfully manufactured” and afterwards those was again separated. Since that time the Fritz box makes nothing at all more.

Has possibly who a notion, that could lie and/or. how I the Fritz box again for running war? I cannot use the UFO, because thereby Internet goes only with a computer and/or. Telephoning and Surfen are at the same time also impossible, one of both are always interrupted.
(, Therefore I had called already times with the Hotline. Result were 30 euro telephone costs, a UFO that only from time to time times into its attitudes lets me look and the information “Tja, there does not know I now also, what has that. Nen other one rout cannot we to them however not offer. “)


UPDATE:

Question is void, I degrees with the o2-Hotline called. After nem line restart (and the mandatory Rffel, why I do not use the UFO) geht's again!
