The analog desk phone thing might not have been so smart. It is the Gigaset DA710, which I connected to the analog input on the router. I still had to hang the adapter supplied by SC between them, but the device doesn’t budge now. Do I have to set anything else on the Internet Box?

Have you also tried Anschluss on the second analogue?

Which Internet box do you have, Plus or Standard?

The Internet Box Plus looks like the picture below.

Normally, with analogue telephones it should work without any major problems if the correct cables are available.

First of all, thank you for the quick reply!

I have the Plus Box and the print screen from you, which exactly matches my view here. Only that I can still see my own number on both of them.

On the second Anschluss I have a Gigaset SL400 wireless, analogue radio telephone (that works perfectly). Could that be to blame?

I’ve just hidden my number in the picture, I’ve never tried connecting two analogue telephones at the same time, it shouldn’t be a problem.

Try unplugging the second one and then connecting the one that doesn’t work.

Unfortunately, replugging doesn’t help. I suspect the problem is with the RJ11 to T+T converter. There are pin assignments on there. 2a 1a 1b 2b. In the past, you had to remove that little green tab on the telephone plug so that you could plug the telephone in the other way around.

Could it be something like that here too?

It looks like the pin assignment is not correct, it should or must work.

Can’t you use the cable from the working phone as a test?

This is a pure RJ11 cable that goes directly into the house cabling and comes out of the wall about 7m away. Then plug in the base station of the SL400. I have now unplugged the base station and plugged the DA710 into it. Things are going well there. What do I do now?

As a result, you still have a special socket that directs the analog signal from the Internet box back into the internal telephone network.

No I haven’t. It only has the purple plug, which goes from the box into the SC socket. The RJ11 cable only goes into a kind of extension socket in the other room. According to my logic, only this ‘RJ11 to Raichle converter’ can be to blame. I’ll try to find an RJ11 to RJ11 cable later. It should work with that.

and that was the problem! Bought an RJ11 extension cable and everything works as it should.

Thanks for the assistance!

Hello

Just for the sake of completeness: If you want to keep your ISDN/analog telephones and/or want a little more “comfort” than with the IB… Fritz boxes can help. I bought my first one -, DECT and SIP telephones. The configuration is not entirely trivial, but it works, even with the name being transmitted to the telephones during calls.

So I actually expect internal calls/transfers from the IB, otherwise two analog connections somehow don’t make sense…

The IB just has to work for the masses. If you want more (and don’t want an SME subscription…) you have the option of adding your own equipment, with SIP even digitally without loss of quality and with several lines.

The extinction of ISDN has really been foreseeable since the last century… pneumatic tubes were also a great technology 🙂
