2 instances of my number

We run on ALL ports in the range of 5060-5080. If you already have something in 5060, register to us using an alternate port.

I tried my ZyXel phone as a second existence of my VOIPo number.
It registered "sip:313432xxxx@192.168.0.xxx:5070"
But now it looks like my Grandstream won't show in vPanel

Initially I get a dial tone

On the ZyXel I get a busy tone when I try to call.

On the ZyXel I get "Comedian mail" greeting when I type 123

I can call out from the Grandstream and calls go straight to voicemail.

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 ...

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...
