You need SPAN port access to all traffic from the call servers to which the phones and gateways are registered.  Usually, phones and gateways are registered to the Subscriber.  However, in a failover situation, the Publisher may take over the call processing functions.  Ideally, you would have SPAN port access to all traffic from the Subscriber and the Publisher; but at a minimum, you should SPAN the Subscriber.
