Currently Ports; Currently Handled Ua - Snom 4S NAT Filter Admin Manual

The Source/Destination indicates the IP address where the
packet was sent or received. The Header column contains the abstract.
By clicking on the header link, you may see the complete packet.

4.8 Currently Ports

It is important to see which calls are active on the SBC. The Cur-
rent Ports web page lists the calls where the NAT Filter performs relaying
on media.
The from and to-field show which participants are involved in this
media relay. The Ports column lists the ports that are used for relaying
the media. Usually you will see four ports (two for incoming RTP/RTCP and
two for outgoing RTP/RTCP). The Receive and Send columns indicates the
bandwidth that is currently used on this call. The unit is kbit/s measured
over a period of five seconds.
In the example, there are two calls. The first call has not trans-
ported any media yet. This is a typical situation of a ringing phone or a
failure that can not be fixed by the NAT Filter. The second call shows an
active call of a user agent that is behind NAT and routes the traffic trough
the server.

4.9 Currently Handled UA

This table shows the currently handled UA with their SIP URI and
their associated IP address. The third column shows the SIP request type
that this binding is using. Typically, this will be a REGISTER or SUBSCRIBE
request.
User agents may have more than one entry. In this case, they
might have dangling registrations on the registrar; this typically happens
when the call-id is changed during a re-registration. From the NAT Filter
point of view, this is no reason for concern.
