4.11 Current Ports

It is important to see which calls are active on the filter. The
Current Ports web page lists the calls where the filter performs relaying
on media.
The from and to-field show which participants are involved in this
media relay. The start column shows you when the port was created.
In the destinations field the user may see more information about
how the different streams in the SDP are mapped. Each line consists of
information about one stream. The number in bold before the stream
shows the stream index. If that stream has been mapped to another
stream, the number in bold behind the colon indicates what stream it
has been mapped to. The number behind the space shows the index in
the SDP. Because a conversation can have more than one SDP, the index
usually occurs in several places. The indexes are matched by their value,
according to their position in the SDP. The next number in bold shows the
port number.
The next field shows the default destination that was indicated in
the SDP. If the destination has not been locked, that address is shown in
brackets and the list of learned addresses is shown after it. An address is
locked when the NAT Filter received a packet on this port from the location
indicated in the SDP.
