FXS H.323 VoIP Gateway User Manual

Step 4. Gateway must enable the IP Sharing function for the fixed/dynamic WAN IP Address.

Fixed IP Address:

usr/config$ ifaddr –ipsharing 1 210.11.22.33

Dynamic IP Address:

usr/config$ ifaddr –ipsharing 1

Note:

With Dynamic WAN IP Address, a valid Gatekeeper for Gateway to get register on is a

must. In other word, it is not workable in Peer-to-Peer mode while dynamic WAN IP

Address.

Step 5. Ather the configuration [commit] and [reboot] the device.

usr/config$ commit

usr/config$ reboot

Step 6. IP Sharing device must have a function to do IP/Port mapping. Some is named as DMZ,

some is named as virtual server whatever. The VoIP messages from WAN have to

completely pass forward to the LAN. It is said if the Gateway is assigned a virtual fixed IP

Address such as 192.168.1.5, IP Sharing device must forward the VoIP message to

192.168.1.5.

Important Notes:

For some IP-Sharing devices do not support DMZ or virtual server function, but allowed user

to allocate some particular TCP/UDP port range.

While a complete H.323 communication is established, the following ports are possibly to be

used:

TCP port:

Q.931/H.225 1720

H.245 Dynamic,

But range 1025 ~ 1029 (not in use if Fast Start or Tunnel mode is

activated)

UDP port:

RAS Device: 1024,

Gatekeeper: 1719

RTP/RTCP Adjustable,

Default: 16384 ~ (16384 + 4*Line Numbers)

1 2 ... 86 87 88 89 90 91 92 93 94 95 96 ... 135 136
