4.240 NAT Address Type: The Axxess system supports traversing near-end NAT using stati-
cally assigned NAT addresses. This capability allows an Axxess system to be placed inside a
NAT or firewall and still communicate with IP endpoints outside the NAT/firewall.
4.241 System v9.1 or later software can be programmed so that each IP endpoint could use
either the Native address or the NAT address. In other words, the system could be programmed
with corresponding IP addresses for communicating with each IP endpoint, whether the end-
point was located inside or outside the NAT/firewall. You can choose one of the following
options:

MANUAL VERSION 11.0 – May 2008
Audio Stream Receive Port: The Audio Stream Receive Port defines the first of 33
even port numbers that off-node IP devices use to transmit audio data to the IPRC. You
must choose an even-numbered value. The base audio port number, plus 64 additional
port numbers, cannot conflict with other port numbers the device uses (e.g., call control
port). For example, if the base audio port number is 5000, no other port numbers on the
IP device can fall in the range from 5000 to 5064. Changing the Audio Stream Receive
Port resets the IP device. To change the port number, click the current Value and enter a
new value in the text box. Then press
change. The valid range is 1026-65468, and the default is 5004.
Password: You should program a password that is require for connecting to the IP
device using a telnet or Web interface. The device also uses this password to connect to
the IPRC. To enter or change a password, right-click the current Value and select
. The Edit Password dialog box appears. Enter the password, up to nine char-
Password
acters, and then confirm the password in the available text boxes. The password appears
as asterisks (***). Then click
For security purposes, Inter-Tel recommends that you program a password for all IP
devices.
Call Control Timeout: The Call Control Timeout field determines how long the system
will wait (in seconds) between heartbeats before it determines that the IP device is
offline. To change the number of seconds, use the scroll box to select the new value.
Then press or click another field to save the changes. The valid range is 1-300

seconds, and the default is 15 seconds.
IP Terminal TCP Call Control Port: The TCP Call Control Port identifies the port
number that the device uses for call control. To change the port number, click the cur-
rent Value and enter a new value in the text box. Then press
field to save your change. The valid range is 1024-65535, and the default is 5004.
IP Terminal General Purpose UDP Port: The General Purpose UDP Port identifies
the port number that the device uses for general purpose and broadcast messages. To
change the port number, click the current Value and enter a new value in the text box.
Then press or click another field to save your change. The range is 1024-65535,

and the default is 5567.
Native: Used when the endpoint is located inside the NAT (those that do not pass
through near-end NAT).
NAT: Used when the endpoint is located outside the NAT (those that do pass through
near-end NAT)
Auto: Allows the IP endpoints to be moved inside or outside the firewall (NAT) with-
out programming intervention. This is the default value. See below for details.
NOTE:
The "Auto" option is not applicable to SIP Trunks, MGCP Gateways, and
MGCP Endpoints. You must manually select the NAT Type setting (Native or NAT).
