Quick Installation Guide
IPF-3000
-15-
Note 1: Since the network administrator has to configure the NAT/firewall to map
those UDP ports to your IPF-3000, thus you should use static IP instead of
DHCP as your network configuration. Otherwise you take the risk that the
IPF-3000 would get a different IP from the currently set into the mapping
when it reboot and re-get its IP by DHCP.
Note 2: If there are several phones reside under the same NAT, their NAT port
mappings must not be overlapped since they all share the same NAT resource!
z Configure SIP service signaling port:『Main Menu』=>『6.Network』/『2.SIP settings』
/『1.SIP service』. Take the scenario above as an example:
1. Transport: 1 (or 3, you must include UDP anyway).
2. SIP port: 10101
z Configure RTP ports by going to 『Main Menu』=>『6.Network』/『3 RTP settings』.
Take the mapped ports as an example:
1. Base: 10102 (Must be an even number and between 3000 and 65532)
2. Range: 6 (Must be an even number and larger than or equal to 4).
Note: RTP ports are used for voice media transmission. Those ports must be
consecutive and start with an even number. Besides, at least 4 ports are needed
for a phone equips with a capacity of two concurrent calls, where each channel
needs 2 ports for RTP/RTCP.
z Assign static NAT IP by going to『Main Menu』=>『6.Network』/『4.NAT & firewall』
/『3.Static NAT IP』 and fill in the acquired NAT IP from network administrator, such
as 210.95.168.1 mentioned above (you may also detect your NAT IP by STUN
from 『Main Menu』=>『6.Network』/『4.NAT & firewall』/ 『1. STUN』/ 『2.
Diagnose NAT』).
Note : if your NAT equipped with no fixed IP, such as those NATs dial into WAN by
PPPoE, then you must synchronize the NAT IP currently set into IPF-3000
whenever your NAT IP changed (Such as NAT re-dialup). By default, the
system will auto-detect the NAT IP (if the STUN server configured into
menu-6.4.1.1『STUN server』is viable) and notify you by sending an instant
message whenever it determine a mismatch between the NAT you configured
into menu 6.4.3-『Static NAT IP』and the one it auto-discovered by STUN
protocol. Alternatively, you may go to『Main Menu』=>『6.Network』/『4.NAT
& firewall』/『4.Dynamic NAT IP』and enable『2.Update by STUN』to
auto-refresh the newly changed NAT IP into menu-6.4.3『Static NAT IP』
whenever it detects an inconsistency.
z Enable Assigned static NAT IP by going to 『Main Menu』=>『6.Network』/『4.NAT
& firewall』/『2.UDP traversal』, selecting『2.Static NAT map』and press【HOLD】
to confirm activation.
