Hello allerseits!!
As new A RISERs in this forum equal a longer contribution:

I used so far a similar TK-plant, actually wanted I these by the telephone function of the Fritz box to replace, and beside which 3 similar branches also 4 of ISDN telephones to attach.

At present the following configuration:

Similar telephone connection
Fritz box 7170 verse. 29.04.21
IP-Telefonieanbieter: 1&1 (four IP call numbers from own preselection range,
Analog line is not as IP call number
configured)
3 similar apparatuses
for the time being 2 borrowed ISDN telephones FMN alpha euro 3000 (to test purposes)

The following problems oppose from my view of the use of the Fritz box as replacement for the existing telephone system:

1. It is not possible to deactivate with the ISDN apparatuses the spontaneous office getting. Possibly this is also not at all intended, in the menu of the Fritz box is available this attitude only with the similar branches. If at the ISDN apparatuses the combination #1Nst planned for deactivation. (51 or 52) *0* is entered, then service does not appear available “in the display „.
Does someone know, how one gets this nevertheless?
If need be it would go also with spontaneous office getting, only would be pedantic the constant preselection of „** “.

2. No matter whether a call of the office, over Internet or a branch, if this call at a digital apparatus is received can one comes further inquiry with the other ISDN apparatus hold, also held the first discussion, but separated with the attempt of the Weitervermittelns (listeners of the first ISDN apparatus present), the connection.
A Weitervermittlung on a similar branch folds against it.
Since this function for me is very important, and those three similar branches do not hand, would not be the use of the Fritz box posed as PABX in question.

Who can help???


Still tap for here the more frequently raised problem of the Nichtklingelns of the ISDN apparatuses from the similar fixed net:

With the ISDN apparatuses also the number of the similar fixed mains connection must be registered as a MSN in the ISDN apparatus, otherwise the apparatus does not ring. (Completely for a long time lasted, to I on this idea came).

Hello Harald111!

Willkomen in the forum!

to 1.: Why do you want to absolutely deactivate the spontaneous office getting?
The 7170 nevertheless straight recognize to “**” that an appropriate internal branch to be called are. It does not disturb itself thereby at the spontaneous office getting.

zu2. I can for the moment nothing else say it with me functioned.

zu1 I wants to deactivate the spontaneous office getting for similar and digital apparatuses, since I would like to telephone internally without “**”, external preselecting of the “0” at my family by at present the still used similar TK-plant the habit became, this would like I to change reluctantly (habituation effect).

to 2 it gives me hope to come by further trying nevertheless still to the result it is good to hear, if it functions with someone else.

Greeting
