Hello everyone, 7390 does not see the subscriber's number on the landline, before there was an old man 7050 and it perfectly identified all incoming numbers, German PBX but an analog line is used, Annex A was selected in the settings, I used different software versions, initially, German software was installed from the box, Annex B, now the international version of the software Annex B is installed, contacts 3 and 6 in the connector are used for connection, according to this description,

although on the old man 7050 contacts 1 and 8 were used, but in 7390 this is the ISDN group,

Thanks in advance!

Instead of the old man 7390, use the vintage 7050 again for this purpose.

Вместо старого 7390 снова используйте для этой цели винтажный 7050.

Yes 7050 is a very reliable product!, I would never change it, but I needed a VPN to connect to 7590, so I had to install 7390, which unfortunately turned out to be worse judging by this discussion

That's exactly what I said!

Yes, I tried to ground the 7390 and shorten the cable additionally, but unfortunately without result, now I additionally ordered an ADSL splitter to clear the analog channel, but I have a network connection via LAN1 without DSL, so I don’t think that will help, it’s a pity that the quality of AVM products is falling, before they really made very reliable and high-quality things.

They still do, but every electronic may fail sometimes.
And remember when your 7390 has been produced.
