Siemens GigaSet DX600A TCP port 650 protocol looks like old-school AT commands…

While playing around with nmap to view some of my IoT^w LoT devices, I found out my Siemens GigaSet DX600A ISDN (yes: ISDN; I’m an old fart) has these two ports open:
PORT STATE SERVICE VERSION 80/tcp open http Siemens Gigaset A580, DX800A, or S450 VoIP phone http config | http-methods: |_ Supported Methods: GET POST |_http-server-header: | http-title: Site doesn't have a title (text/html). |_Requested resource was http://dx600a-isdn.pso71.local/login.html 650/tcp open telnet Gigaset telnetd MAC Address: 7C:2F:80:15:D6:10 (Gigaset Communications GmbH) Device type: general purpose Running: Linux 2.6.X OS CPE: cpe:/o:linux:linux_kernel:2.6 OS details: Linux 2.6.13 - 2.6.32
I’m going to play with port 650 later as it looks like it supports an AT command protocol(on Windows the GigaSet QuickSync TAPI driver translates TAPI to AT commands) so it should be possible to do all kinds of cool stuff with it.
These links should help ans it should work with the DX800A as well:
