I actually think it's just a poor title, "my server runs on a phone now" would be better.
As it is, I expected the server to now have a modem, to be operating as a phone.

The author should have swapped the title with the subtitle: "rooting a CMF Phone 1 to run my personal infrastructure at home".
To me it was a clear and a very fitting title.
(But my first language is german, maybe that has some influence)
