Joining through SIP into a zoom meeting

I’m trying to connect into a zoom meeting through a SIP phone / library
But always I’m getting “SIP/2.0 480 Temporarily Unavailable” without any explanation of what could be wrong.

We have plenty of zoom room connectors ports so I don’t think that is the problem

Thanks,
