Connection:

As shown on the diagram above, connect the 2 V-Servers' Ethernet ports to a Ethernet hub using 10 BaseT Ethernet cables. For each V-Server, connect 2 phone sets to phone 1 and phone 2 port of the V-Server respectively.

Configuration (for each V-Server):

First, you have to configure one of your box to a DDA. Click here for an instruction.

Then need to configure the Ethernet and Phone Number Dialing part. The Quick Start Guide gives you the instructions. 

Making Calls and Sending Fax:

FXS:
How to Make Call

FXO:

First you have to configure a phone port as FXO. Click here for an instruction.


Connect external PSTN phone lines (that is, a regular phone line connected to the walljack and through which you can make regular phone calls) into the line ports correspond to the phone port you just have configured to FXO. For example, if you have configured phone1 to FXO, then connect the LINE1 port to the PSTN line.

Making outgoing calls:
From the any of the FXS phones (ports) on the 2 V-Server, dial  the FXO port phone number. You will hear a dial tone. Dial any phone numbers (like your home number) you like. You can't use the phone port you have configured to FXO to make calls.

Making incoming calls:
Dial the phone numbers of the PSTN line on which you have connected  the FXO port. After hearing another dial tone, dial the FXS phone port number you wish to reach. You can't make incoming calls to the phone port you have configured to FXO.

You can test Fax in the same way you make calls.

LAN to Internet

In this model, V-Server works as a terminal in a LAN and gains Internet access through a Router. Voice call and Fax transmission can be made between this V-Server and other V-Servers on the Internet.

lan_to_internet.jpg (24632 bytes)

Connection:

Connect the V-Server into your LAN. Attach phone sets to the V-Server phone ports.

Configuration:

Configure the "Ethernet" part and "Phone Numbering Plan" under the "Configuration" on V-Express. Make sure you configure a Dynamic Dialing Administrator (DDA) under the Phone Number Dialing Plan (part 2) if you are not using a H.323 Gatekeeper.

The Quick Start Guide gives you the instructions. 

Note:
1, The IP Address here have to be a real IP Address.
2, The gateway IP address is the IP address of the router and this address and the Ethernet address of the V-Server must be on the same subnet.

Connection:

Connect your ISDN line to the V-Server ISDN port. Attach phone set or Fax machine to the V-Server phone ports.

Configuration:

The Quick Start Guide gives you the instructions. 

Please contact our technical support personnel if you have any problem.

Connection:

Connect the V-Server Ethernet port to the Cable/DSL Modem Ethernet port using a 10 BaseT Ethernet Cable. Attach Phone or Fax to the V-Server phone ports.

Configuration:

The Quick Start Guide gives you the instructions. 

Set the Cable/DSL Modem IP address as the V-Server Ethernet gateway address.

Note: try to reset your Cable/DSL Modem if you have trouble connecting to the Internet after the configuration.

NetMeeting

NetMeeting.jpg (46846 bytes)

Connection:

Connect a V-Server to the Internet using ISDN, Modem (including Cable and DSL Modem) or LAN (behind a router). Connect a PC with NetMeeting Device to the Internet using LAN, dial up or any other means.

Configuration:

For V-Server: In V-Express, go to H.323 Compliant Device List under Phone Numbering Plan.
Enter the Name (no space allowed), Phone# and IP address of the NetMeeting in the corresponding fields. The phone number is only to make calls to the NetMeeting from the V-Server phone port, so you can make up any numbers, like 12345. IP address is the IP Address of the PC having the NetMeeting. Check the broadcast "On" if you would like to let other V-Servers in a group to be able to talk to the NetMeeting.
Click "Add/Change" to add to the list. Save the configuration, reset the box.

For NetMeeting: Important: Only 2.1 or higher version of the NetMeeting will work with the V-Server. NetMeeting 3.0 Beta set up may be slightly different from that of 2.1 described here.
Go to the NetMeeting, Select "Option " from the "Tools" menu.
Select the appropriate Bandwidth from the "Network Bandwidth" under the "General" tab. We strongly recommend user to use the "28800 or faster modem" option. User may not be able to make complete calls using other options.
Click "Audio" Tab, Check "Enable Full Duplex Audio..." if you have a full Duplex Audio/Sound card.
Check the "Use H.323 Gateway" check box and enter the V-Server IP address into the box.
Click "Advanced" button on the "Audio" tab.
Click on the "Microsoft G.723.1, 8KHz Mono, 6400... " entry and click on the up button to move the entry on the top of the list. Click "OK".

To Make Calls:

From V-Server: Dial *0 and the NetMeeting Phone Number (like 12345) you have entered in the "H.323 Compliant Device". The NetMeeting should display message telling you that you have a NetMeeting call. Make sure the NetMeeting application is open and running on the PC when you make the call.

From NetMeeting: Click "Call" Button, Select "H.323 Gateway" from the "Call Using" drop down box.
Enter the phone number of the V-Server (without prefix) in the "Address" box. Click "Call". 

Note: If you are not testing the NetMeeting call within a Private LAN shown on the diagram, please make sure your NetMeeting PC has a real IP address and it is not behind a firewall.

If the call is only one direction, please click here for a solution.

V-Server Routing Function

This model tests V-Server access to the Internet directly through the V-Server build-in router function. Voice call and Fax transmission can be made between this V-Server and other V-Servers on the Beta test network. V-Server also routes data in and out from the Internet and the attached private LAN. V-Server Supports RIP, Static Routing, NAT (Network Address Translation) and Priority Routing.

V-server_as_router.jpg (9879 bytes)

 

Connection:

V-Server connects to the Internet through PPP connections, either ISDN or through serial port. You may connect a PC's Ethernet port directly to the V-Server Ethernet port or connect both V-Server and PC to a Ethernet hub. You may attach a phone or Fax to the V-Server phone ports.

Configuration:

Configure the ISDN or Async Connection first.

Configure the IP Routing under the "Configuration Profile" in V-Express. Please refer to the following section for an example.

An Example: How to Configure the V-Server's Routing and NAT Function to Set Up a Private LAN?

This example is advanced user only and it is given in command-line commands.

Following Example Demonstrates the Connection and Configurations of the V-Server Routing Function and NAT Function.

The reason we are using the NAT is that it can translate the private IP addresses to a single real IP address and so we don't have to buy those real IP addresses for every of our network devices.

In this example, assume the V-Server Ethernet IP address is set to a private IP address 192.168.2.1 and set the PC1 and PC2  IP Addresses to 192.168.2.2   and 192.168.2.3. The V-Server Ethernet IP and IP addresses of any network devices (like the PC1 and PC2) attached to the private LAN should belong to a same subnet.

Only the ISDN IP address assigned by the ISP (Dynamic or Static) is a real IP here.

 

V-Server as router.JPG (35144 bytes)

 

Ethernet Configuration:

set ethernet ipaddress 192.168.2.1

RIP Configuration:

set rip dir in

set rip sh simple

NAT Configuration:

set nat option on

set nat port 60000

PC Configurations:

Under the TCP/IP setting found under the "Network" setting, set PC (PC1 and PC2) gateway to the V-Server Ethernet IP address (192.168.2.1).

When the ISDN link is up, the V-Server will automatically updates the NAT IP address to the ISDN IP address.
