I'm playing with SIP phone service at home, I'm looking at setting up
service with a UK number - to have a local call for them connecting to
a SIP phone here in the US.

I should play with MFA and see if providers complain about SIP numbers
for MFA.

I have heard of people setting their own SIP or other phone exchanges at
home. How do you prevent yourself from setting up a number that is
already taken, or do you need a service provider who takes care of that?

You can set up SIP-to-SIP calling on your own and make SIP calls to
other people over the internet but dialing out to the PSTN requires a
SIP trunk provider, who provides the number.

you need a provider or you are totally isolated. :)
for example voip.ms for the states.

but you can find .uk providers as well, which will be much cheaper to obtain a UK number, than a us provider.

with asterisk (4example) you can connect as many providers as you wish.

and after that we can connect all of our asterisks and make our own telco. like an intranet or vpn just for telephones. i was thinking about this for a while. so at least we can call each others bbs with our modems for free.

Funny, I was just thinking about XMPP (Jabber) and wondering about setting up BBSes with it.

Ahh, thanks for that explanation. I figured there was a piece of the
puzzle I was missing there. ;)

Dang, now I've got to check out the Asterisk PBX LXC container. I have a SIP line coming into a SIP phone here, assume I could have it land on Asterisk and ring my phone.

Have you ever used IAX2 between a couple PBXes? It sounds so good!

Never did. Most of my telco career was before that, running Nortel
PBXes. Nortel started doing SIP, but it wasn't very open - it was mostly
using their controllers to manage proprietary phones. We did do SIP
trunking between switches, replacing MPLS, and I was going to look at
SIP to SIP with Asterisk for an acquisition we purchased, but we ended
up moving them into one of our existing offices.

This was so early on that the way voice mail systems would exchange
messages between sites was transferring sound files via 2400 baud
modems.
