TinCan owner here. The issue with landlines in my experience is that they quickly become overwhelmed with spam calls. That and the ability to lock down the phone to just a few numbers is the appeal.

Mine, in Spain, is surprisingly free of spam. I receive spam on my mobile phone, which is often blocked by Android, but I don't receive spam on my landline. Strange, isn't it?

Could you do the same thing with your real issue tracking software? Your agent could use an MCP to create a Jira ticket and create subtasks or tasks for your subagents? Then you don't need to clutter up your repo with these MD files and .beads directories and what not.

Yes you can. I've experimented a bit with using the `gh` CLI tool to work with issues in a GitHub repository, but I don't particularly like the aesthetics of having a bunch of LLM-generated prose in my issue trackers like that.
