If you have a line, you can still dial each other and negotiate up to 33.8kbps v.34bis, add better software compression (zstd) instead of depending on v.44, and add encryption algos on each end. v.92 56k needed an ISP end to work.
Companies like US Robotics and Zoom might still make v.34bis hardware modems... see USR5637. Lots of modems on used market.
Full hardware modem with PCM DSP is needed to do elite first pass random phone scanning that analyzes the analog instead of depending on successful second stage "V." protocol negotiation. Plus you get as bonus all the WAV recordings of: "Hello... Helloooooo?! WTF!!!" ;-)
Anyone still have that analysis software?
I understand that WarVOX is at least one of the more modern incarnations of Toneloc, uses VoIP to make a bunch of calls at the same time, other neat tricks.

The modem's onboard ADC would ouput per call PCM stream back over the serial port for later processing, FFT, etc. For sorting and discriminating whatever picked up into fun lists for later testing. US Robotics later models were some that had those extra commands. Maybe hard to find command example docs, and results and wav's, of that now.
