Does this not highlight a wider issue?

I realise that dialup is hardly 'cutting edge' but there are providers out
there with a significant number of dialup customers still on the books.
Surely there's still a market for (what should be by now) a
straightforward, well known piece of kit?

In parts of the world where broadband is not ubiquitous and dialup remains
useful as a Plan-B or is simply the only choice (for whatever reason),
what are the practical choices now?

Whilst folks may not be fielding 'new' dialup kit, I dare say that we're
going to be continuing to see dialup customers on the books for the next 5
years, perhaps a lot longer?  That's a whole product lifespan...

Welcome to what telcos have been dealing with for 10 to 20 years with product lifecycles. The PSTN isn't exactly a growing market, and has lots of EOL switches, yet it continues to run. Secondary support markets, grey markets, and strategic migrations to carry internal sparing.

Or you find a cost effective way to replace it with something; or you accept that the revenue vs. cost-to-maintain is too high and just kill the product.

p.s. UTStarcom was still supporting the [former USR/3com] TotalControl chassis as of about 2 years ago; I don't know if they still do. They were positioning it as a migration platform for legacy X.25 networks.
