So from what you are saying, there isn't a way from an opensips config
to add a presence entry based on call permissions? So there's no way
to for a phone to subscribe to the DND state of another line? The
phone wouldn't be subscribing to the extension, but a prefixed
extension (like *762005551212).
If there's no way to do this, then that is unfortunate, because that
means DND handling will have to be pushed out to Asterisk because this
is one of the features we provide to our users, being able to
subscribe to DND state.

Thanks.
