[ale] Slightly OT: recommendations for VOIP/SIP to replace POTS

[neal at mnopltd.com]

Did the free upgrade to AT&T Fiber yesterday.   So far so good.

Since we're closing the company this year, I broke news to my 
partner/wife that we really should stop paying AT&T $50/month for the 
simulated land line.

We'd like to retain that phone number on a single line SIP, but not 
spend so much.

I've started to look at this, and I deduce that just buying a SIP like 
this

Still requires a cloud provider.

Looks like www.3cx.com offers that capability for free for up to 10 
lines.   Maybe there are other provides which offer better pricing than 
free?

So, seems like this is a viable way of retaining our existing phone 
number to ring in the house, and it behaves just like a land line phone, 
and no ongoing cost.

Yes?

And are there even better/cheaper approaches?
