You can allow someone to see something without allowing them to change
it. And all they really need to see is their SIP URI.

I don't know what difference this makes. If you want to have your own
SIP service by registering your own domain, yes, but either way it is
like an email address. 666666@voipfone.co.uk is a unique user, SIP URI,
(Fine was a freudian slip, I meant fone).

I don't really. I mean a SIP URI. The address is part of the protocol as
it is with email. You can still set up your own email server if you want
to. You just have to know much more than you used to.

You now have to provide DMARC information in the headers yes, but that
doesn't mean you have to use a third party email provider. It is more
convenient as you don't need to configure it.

You can use direct VOIP on a VOIP provider's domain. I am not sure why
this means you have to pay by the minute. A&A allows direct VOIP calls
(if you configure it).

That system will be gone by January 31, and many calls must already be
between VOIP systems.

That's not a reason for continuing to do it.

I can make a video call free but I have to pay for an audio call. If I
am using Google Meet they make some money out of me, but does that
account for the difference? audio is less data. I can use an Amazon
device to make free calls, even to landlines. I had to pay for the
device, and they will try to sell me subscriptions for music, video,
etc.
