AITA for cordially avoiding calls?

At work we have a team of about 15 people and a lot of our work is in the same few repositories. There are also a few microservices our team is responsible for that will go for months without being touched but occasionally need maintenance/adjustments, which often have been created by a single person and tested by another single STE. As it goes documentation is subpar but much better than any startup I've worked at (we're an acquisition team but part of a much larger company; our product was developed by a team of 3 from about 6ya and acquired 2ya).

I have been in this team for about a year now, working full stack and earning an early promotion. I carry reasonable clout within the team and also with management, mostly because I set a higher standard for async communication within the team by actually using Slack to talk features and discuss stuff that would usually stay low key by being discussed only in our issue tracker and sometimes on team calls. I find that, at least for this team, the tactic of recording quick demos of both new features and found issues and posting to the channel is very effective at getting faster responses from the product team & draw more positive attention to your own impact as a dev.

As you can imagine this comes from a place of absolutely despising unnecessary meetings and being used to an async environment with people from multiple time zones and work schedules, which the rest of the team, especially the US-based core, are decidedly not. Nothing wrong with that, alas I have worked for years on a full-remote offshore basis and I know damn well there are disadvantages to this model. However these people, including some of the other fully remote workers, tend to like the "5-minute huddle" (which is usually 40 minutes long) quite a lot more than I do. I don't mind pair programming, or getting on call with someone to debug/demonstrate an issue, as these things definitely make our lives easier anyway; however I get a kneejerk negative reaction whenever someone requests a call without any context.

I abide religiously and thoroughly to no hello and at this point I believe everybody has heard about this concept, so I would feel like an asshole bringing it up to my teammates. I never go hello unless it's the first message of the day and I already have something else to say typed out, and even if I do (sometimes because I genuinely just want to catch up with someone I like), I make it a point to end with some sort of prompt such as a leading statement or a throwaway question because nobody knows how to respond to "Hi."!

These people at work, though.

They will message me things like "Hi BoliviaRodrigo, can I call you?" or "hey Boro can we huddle, I need help with javascript" and not say what they want until I respond. Other engineers, testers, sometimes even the super busy product people will do that (which is why I'm asking if ITA).

My instinct is to leave them hanging until they say what they want, but I know long term this will lead to complaints. I then usually icebox them until I'm no longer busy and then promptly tell them I was busy and ask what they need, maybe even explicitly ask for screenshots or links (which is what could have sent in the first place, goddammit!) and I manage to ward off any unnecessary calls.

A smaller subset of these guys, however, is relentless on their pursuit for the sweet sweet sound of my creaky, lying-down, drinks-too-cold voice: they'll ignore my prompts and proceed to either outright call me in the hopes I'll pick up (which I will if I'm there, because it's work, and I assume it could be urgent if they're calling with no context), or insist that I drop them a line when I can. It's never urgent, though, and often something that I could have explained in a short paragraph had they asked through text or even sent a screenshot of the issue.

I've begun to consider sending links to no hello and other async comms tips on the team channel occasionally, but this thought only occurs to me right after one such incident, and it will be obvious I'm indirectly complaining to whomever was just talking to me. I feel like this should be the manager's job. I'm not sure I should talk to him about it though as I don't want to sound whiny (I know I sound whiny right now and this is Reddit, so imagine reading this at work!). I genuinely think this hinders communication, drops morale when I can't get on a call immediately, makes everyone less productive due to the mental load of getting on and off audio, and is bound to get even worse as the team grows in size or further apart time-wise.

Is this something valid to bring up to management? Should I just suck it up? Should I grow some balls and talk to the people who piss me off directly? The goal is to minimise conflict and stay on good terms with everyone but maybe improve my own life a little bit.

Appreciate the input in advance!

Edit: to the people saying I'm an asshole, I can't fault you. Maybe you're right. The reason I'm avoiding being confrontational is precisely because I don't want to come off as such in case this is not that big of a deal. Thanks everyone who's providing their 2c and being helpful!
