2 instances of my number

Perhaps you will use MAC IDs? (Limit/control multiple instances.)
And have a place to register such an ID.
Then VM can work the same.

Still not sure about dialing out?
I can gget to VM by 123, then my number and my password.
Dialing out always fails.
codeblue.voipo.com:5060 seems necessary to register
even though the ATA can be codeblue.voipo.com:5070 (See image on earlier post.)
