TCP/TLS Parameters:
Mapped TCP Host
requires the IP address of the mapped host for SIP TCP traffic over NAT.
Mapped TCP Port
requires the port number on the mapped host for the SIP TCP traffic over NAT.
Mapped TLS Host
requires the IP address of the mapped host for SIP TLS traffic over NAT.
Mapped TLS Port
requires the port number on the mapped host for the SIP TLS 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
QX1000. 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.
Fig. II-165: STUN Parameters page
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
lists all possible IP ranges that are not included in the NAT process, but may be accessed directly. IP addresses that are
not listed in the
NAT Exclusion Table
are accessed over NAT. For example, if a QX1000 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.
Add
opens the
Add Entry
page where a new IP range can be
added.
