2 instances of my number

[usa2k]

I rebooted the Grandstream and they both show now
"sip:313432xxxx@67.149.75.xxx:33496"
Incoming works to the Grandstream now.

Main config info for ZyXel

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.)

Both Grandstream and ZyXel show they are registered

Only the Grandstream can place calls.
The ZyXel is not interfering with incoming for Grandstream.

Both show registered on vPanel.

BTW, I have P8 forwarded to VOIPo number.

It looks confusing to have the P8 phone still as one of my two lines, because P8 still rings once or twice even though VOIPo is ringing (And that is P8's forward option - not simul-ring.) So I am leaving P8 unconnected to any phone.

Forwarding should not interfere with my P8 LNP to VOIPo. It never affected Vonage to P8 ...

In a "double device" scenario, it isn't always sent to both devices on incoming calls.

The "last" device that sent a register for that period gets precedence for anything.

You may want to disable to unregister before register feature/s if they exist on the ATA.

You can also do "make outbound calls without registering" so it will still attempt the outbound call and should make it if the outbound proxy information is correct.

Really outbound is all I am looking for. The odds of using the second line is rare, but it is just comforting to have the option.

When I had 5060 before, it worked outbound - I should try that again. It seemed to mess-up the inbound to the Grandstream. I've got a busy night, and I am out of town tomorrow, but I will have time to play Wednesday.

Look a bit later...

Some ATA's have a "Initial Unregister" that they send to the server that wipes it clean of any other registrations.

I dont know if its only at boot or at every registration attempt.

Might be what happened to you...
