I have the Archer VR2100V DSL Router and want to connect and use Fax with it. I bought an Epson all in One Printer.

Currently I was only able to send a fax to a 0180 number in Germany successfully - everything else is not working. I can hear the dialing and transmission but there is nothing received with local numbers.

My DSL Provider 1&1 suggested me this article.

Wie kann ich den WAN-Datenverkehr meines Archer VR aufzeichnen? | TP-Link Deutschland

Unfortunately telnet is not working the article only refers to these DSL Routers so I can not provide them with any Wireshark capture. 

Archer VR900v( V2 ) , Archer VR2800v( V1 ) , Archer VR600v( V1 V2 )

Is there any possibility to connect via telnet to the archer vr2100v router?

Any Idea why it is not possible to send a fax to local numbers?

Ask Telekom for an appointment perhaps the Fax machine (Espon All in One) can be connected directly via phone box? Not sure if I have ISDN or needed?

Mit freundlichen Grüßen
