Can you let me know whether a question would be on-topic here?

I want to ask a telephony theory question about fax hardware compatibility with the VOIP dialing protocol.

My understanding is that VOIP uses a different dialing protocol than landlines. This apparently causes problems with some fax hardware being unable to get a dial tone and make the connection. There are various workarounds, like setting line type to PBX and dial tone detection off (which doesn't always work).

I want to ask about any fundamental incompatibilities that would prevent some fax hardware from making the initial connection, and any specific hardware requirements that relate to the ability to do that (e.g., is there a spec I could check to know whether particular fax hardware would be expected to dial and connect with VOIP?). The question was originally triggered by some ancient hardware that doesn't work with VOIP, but my research indicates that it is an issue even with current hardware.

I see the site has a telephony tag with a small number of questions. I couldn't get a sense of whether this kind of question would be on-topic. I found what seem to be somewhat related questions previously discussed here:

Perhaps a related consideration, I'm guessing this isn't a site for novices. So even if the question would be on-topic, would a novice be likely to understand the answer?

In my opinion, this question would be better suited at https://serverfault.com. As you observed, questions about VOIP are quite often off topic here, and not many questions about VOIP are asked. will most likely be more willing to accept the question, and also has more people able to actually help you with the questions you have.
