SIP Operation Manual
RTP Starting Port UDP: The initial value of port number of transmitting voice data among
gateway(s). Each line requires 2 ports (RTP/RTCP). It is not necessary to change these,
unless it conflicts with ports used by another network device.
For example:
If the starting port is 9000, then Line 1 is using 9000(RTP) and
9001(RTCP), and Line 2 is using 9002 and 9003, and so forth.
IP Configuration (Setting WAN Port)
There are five methods of obtaining a WAN port IP address:
1. DHCP, which means a Dynamic IP (Cable Modem)
2. Static
IP
3. PPPoE (dial-up ADSL)
4. PPTP.
5. BigPond (for Australia only)
Methods for using DHCP and PPPoE for obtaining an IP address may vary. If you are not familiar
with creating a network connection, please contact your local ISP.
Setting Dynamic IP (DHCP)
Click
DHCP
to obtain a Dynamic IP address, and then click the
Accept
button at the bottom of the
screen.
Click
System Operation
to select
Save Settings
and
Restart
. Wait for a while (about 40 seconds),
and the system will obtain the related IP address from the DHCP Server.
NOTE: After the system has obtained a new IP address, if you are using a WAN port to enter the Web
Configuration Screen, the new IP address has to be used. The system takes about 40 seconds to restart.
The same principle applies to the next two settings.
Setting Static IP
Select
Static IP
and enter the IP address, Subnet Mask and Default Gateway values. Then click
the
Accept
button at the bottom of the screen. Save the settings, and then restart the system.
