No, that is wrong.
What you have below is a voicemail notification. You have to remove the
mailbox= in the peer configuration in order to not have any voicemail
notifications.

The reason why this error message is coming up, is that the device
should SUBSCRIBE for the notifications in order to get them.
Out of habit, Asterisk sends these without subscriptions as default,
but you can configure asterisk to handle this on a subscription
basis.
