Still, I see no differences with a second number/burner phone.

For e-mails, a strategy I used and that worked (at a time I had a domain with its own mail server) is to give a "non-existing" e-mail, like [e-mail], the mail server was set to have a "catch-all" account, so [e-mail] would arrive (together with messages to [e-mail], etc.) to this catch-all inbox, while identifying by the address used the "source".

With telephone numbers, a possibility would be to fake a PBX with internal numbers (no idea if it is feasible) i.e. if the relay main number is 123456789, have it working with added "internal" numbers, such as 123456789101, 123456789102, etc.

That's because that's essentially what this is :)

And yes, that's how Relay for email works (although instead of using mydomain.com, you use mozmail.com, so your different email masks can't be linked together).

We'd definitely like to support a similar pattern for phones, but we still have to figure out a way to do that. Using extensions is one thing we'll be looking at (was also suggested at [1]), but a challenge there is that many services have rather strict validation rules on phone numbers that will disallow that. But it might still be worth it, so stay tuned!
