for the SIP TCP traffic over NAT.
The
RTP Parameters
page is used to choose between the
STUN and Manual NAT traversal connection for the RTP traffic
and to define the RTP/RTCP ports for the connection over NAT.
Manipulation radio buttons allow you to select the type of
connection over NAT:
Selecting
Use STUN
will switch to automatic discovery of
Mapped settings for the RTP UDP traffic over NAT. STUN
settings are configured on the STUN Parameters page (see
below).
Selecting
Use Manual NAT Traversal
allows you to manually
define the RTP/RTCP port ranges for the RTP traffic over NAT:
•
The
Mapped Host
text fields require the Mapped Host for
RTP traffic over NAT.
•
Mapped RTP/RTCP Port Range:
Min
- minimal port has to be higher than 1024 and lower
than the maximal port range. Only even numbers are
allowed.
Max
- maximal port has to be lower than 65536 and higher
than the minimal port range. Only odd numbers are
allowed.
Please Note:
RTP/RTCP Mapped Port ranges should be
greater than or equal to the RTP/RTCP port ranges defined on
the
page.

The
STUN Parameters
page enables automatic NAT
configuration through the STUN server and is used to configure
the STUN (Simple Traversal of UDP over NAT) client on the
Quadro. This page requires the following data to be inserted:
The
STUN Server
text field requires the STUN server’s
hostname or IP address. The
STUN
Port
text field requires the
STUN server port number.
The
Secondary STUN Server
and
Secondary STUN Port
text
fields respectively require the parameters of the secondary
STUN server.
The
Polling Interval
drop down list contains the possible time
intervals between referrals to the STUN server.
The
Keep-alive interval
text field provides the options to select
the time interval (in seconds) for keeping NAT mapping alive.
The value should be in the range of 10 to 300 seconds.
The
NAT IP checking interval
text field indicates the interval (in
seconds) between the NAT IP checking attempts (used to
distinguish the possible NAT IP address changes and to perform
registration on the new host). The value should be in the range
of 10 to 3600.

The
NAT Exclusion Table
page includes a table where all possible IP ranges are listed that allows you to exclude some network addresses from
being NATed. For example, if a Quadro user needs to make SIP calls within the local network as well as outside of that network, all local IP
addresses are required to be excluded from NAT traversal settings by being listed in this table. Otherwise, a malfunction may occur in SIP
operations.
The
NAT Exclusion Table
page offers the following input
options:
Each record in the table has a corresponding checkbox
assigned to its row. The checkbox is used to delete or to edit the
corresponding record. Only one record may be edited at a time.
An error message will appear if no selection is made or more
than one is selected.
Each column heading in the table is a link. By clicking on the
column heading, the table will be sorted by the selected column.
When sorting (ascending or descending), arrows will be
displayed next to the column heading.
The
Add Entry
page includes the following text fields:
Add
opens the
Add Entry
page where a new IP range can be
added.

Edit
opens the
Edit Entry
page where the IP range can be modified. This page includes the same components as the
Add Entry
page.
