Hello @jtbrown,
I completely get it. You're looking for a simple button to flip, and I wish there was one! It's such a great idea to have the extension numbers show up automatically.
While manually changing each phone's settings one by one is an option, it's honestly a lot of extra work and not the best long-term solution. Your changes could get wiped out by an update, and then you'd be right back where you started.
I think the absolute best and easiest way to handle this is to work with our Professional Services team just one time. They can create a custom template for your Yealink T43U phones, and from then on, every new phone you add will magically provision with the right settings!
It's a "set it and forget it" kind of solution that saves you a ton of hassle down the road.
I hope this helps you find the perfect fix for your phones!

In speaking with RingCentral,  they indicated every time I added a new phone I’d need to open a professional services ticket to have that phone updated.  I too thought they’d just create a custom config file we’d point our phones to,  kinda of a set it and forget it.    If you have any contacts at R/C that I could start the dialogue with that knows what we need,  that would be very helpful.

I'm going to reach out to your Technical Account Manager to get some clarity on this for you. I'll send you a Direct Message here in the Community once I have an update. 🙂
