Therefore you can easily keep contact with your most important customers, business partners, suppliers or employees even if they are away from the office. This solution makes it possible to forward your messages in real time even to multiple recipients.

    To realize this function you need to install Ozeki NG SMS Gateway on your computer. If you decide to implement this solution you will be able to build a stable, secure and well-functioning IT system with the highest quality.

    Checklist for prerequisites

    Here is a checklist that enlists the requirements your system needs to meet. When you start setting up your system, you need to ensure a connection to the mobile network to be able to send out SMS messages. You can connect your SMS system to the mobile network by using an Internet connection or you can setup a wireless connection by attaching a GSM phone/GSM modem to your computer. The following webpage will help you make a decision: Internet based SMS connections vs. GSM modem based (wireless) SMS connections.

    Internet based connection to the Mobile network

    If you wish to connect your system to an SMS service provider over the Internet you need the following components:

    Figure 1/a - IP SMS connection checklist

    In order to setup an IP SMS (Internet) connection for messaging, you need to sign up for the service of an SMS service provider who can reach the mobile phones in your area. This SMS service provider should be able to provide SMS service through the Internet. The following website enlists some of these provider. Please check it to find such a provider: SMPP SMS Service providers. Once you have found the suitable provider and signed up for their service you will get the connection parameters. You can use these parameters to configure your Ozeki NG SMS Gateway software.

    Wireless (GSM modem) connection to the Mobile network

    If you would like to use a GSM device for connecting wirelessly instead of a connection over the Internet, you need a GSM modem or GSM phone that you can attach to your computer with a data cable. In this case your Ozeki NG SMS Gateway software will operate this phone and will send and receive SMS messages wirelessly.

    Figure 1/b - GSM modem connection checklist

    Your checklist (for GSM modem connection):

    SIM Card - You can get this from your local mobile network operator.*
    Modem - Use a Wavecom, Siemens or Multitech modem.
    Data cable - Comes with the modem
    Computer - Recommended: Intel P4 3Ghz, 2GB RAM, 500Mb HDD, Windows OS
    Ozeki NG SMS Gateway - Download it from
    MS Exchange 2003

    *The SIM card will come with a plan, that will determine how much money you will spend on each SMS.

    SMS sending process from MS Exchange 2003

    Once you meet the above checklist you can check how SMS messaging works. The E-mail to SMS function will work as follows:

    If there is an incoming e-mail, it will be forwarded to the user's mail box of MS Exchange 2003 and to the SMTP server of Ozeki NG SMS Gateway, as well. The message will be received with an e-mail address in Exchange, for example,; while the secondary e-mail address contains a phone number and the IP address of the computer on which Ozeki NG SMS Gateway has been installed. For example: "+36301234567@"

    In case of SMS to e-mail function, you need an e-mail user interface in Ozeki NG SMS Gateway but you only need to configure its SMS to e-mail part. The incoming SMS messages will be forwarded through the SMTP server of MS Exchange as e-mail messages. Figure 2 demonstrates this process. Ozeki NG SMS Gateway forwards messages to the mobile network either with a GSM modem attached to the computer with a data cable or it connects to the SMS center of the mobile service provider over the Internet.

    Figure 2 - SMS sending in MS Exchange 2003 with e-mail forwarding using Ozeki NG SMS Gateway

    Configuration steps for SMS messaging from MS Exchange 2003

    At first you need to install MS Exchange 2003 on your computer. In our example it is on the server called "exchange" (Figure 3).

    Figure 3 - Server's name

    The server has a fixed IP address which is "" (Figure 4).

    Figure 4 - Server's IP address

    Now go to "Start" menu and select "Active Directory Users and Computers" console from "Microsoft Exchange" menu (Figure 5).

    Figure 5 - User's and computer's console

    After you have opened "Active Directory", click on "Users" menu item, then right click on the right side of the interface and select "User" menu item from "New" menu (Figure 6).

    Figure 6 - New user

    In the appeared window provide a username and provide a logon name for this user as well, then click on "Next". In our example it will be "John Smith" (Figure 7).

    Figure 7 - User's name and logon name

    In the next window, make sure that "Create an Exchange mailbox" option is checked. Then provide an email address for the user (Figure 8).

    Figure 8 - Exchange mailbox name

    If it is done, click on "Finish". For a better demonstration I create an other user with the name of Edward Taylor.

    Before you go on with the configuration of the server, make sure that the SMTP server of Ozeki NG SMS Gateway is enabled. You can enable the built-in SMTP server if you start Ozeki NG SMS Gateway on the client computer and select "Server Preferences" menu item in "Edit" menu. On "Client Connectivity" tab check "Enable the built-in SMTP server" option. Click on "OK" (Figure 9).

    Figure 9 - Enable Ozeki NG SMS Gateway built-in SMTP server

    Before you return to the configuration of the server, note the IP address of the client computer. In our example it is "" (Figure 10).

    Figure 10 - Client's IP address

    Now return to the server computer, right click on the right pane and select "Contact" from "New" menu in the "Active Directory Users and Computers" console (Figure 11).

    Figure 11 - New contact

    First provide a name for this contact object. In our example it is "ozeki SMS contact". Click on "Next" (Figure 12).

    Figure 12 - Contact name

    Next, click on "Modify" to provide an e-mail address for the contact object (Figure 13).

    Figure 13 - Modify the email address of the contact

    Select the type of the e-mail to be created: "SMTP Address" and click on "OK" (Figure 14).

    Figure 14 - New SMTP address

    On the next page provide the e-mail address in the following way: "recipient@IP address of the target computer". In our example "+36301234567" is the recipient and "" is the IP address of the target computer (Figure 15).

    Figure 15 - Contact e-mail address

    In the next window you can see the created e-mail address. Click on "Next" (Figure 16).

    Figure 16 - Created e-mail address

    In the end you will find a summary about this process. Click on "Finish" (Figure 17).

    Figure 17 - Finish the creation of contact

    Right click on one of the created user and select "Properties" menu item (Figure 18).

    Figure 18 - User's properties

    In the "Properties" window click on "Exchange General" tab to get the Exchange settings of the user (Figure 19).

    Figure 19 - General Exchange settings

    Click on "Delivery Options" tab on "Exchange General" tab (Figure 20).

    Figure 20 - Exchange delivery options

    Check "Forward to" option and click on "Modify" (Figure 21).

    Figure 21 - Modify forwarding address

    In the appeared "Select recipient" window click on "Advanced" option (Figure 22).

    Figure 22 - Recipient advanced settings

    A search window appears with which you can search in the "Active Directory". Click on "Find now" (Figure 23).

    Figure 23 - Find recipient

    Select the created contact object and click on "OK" (Figure 24).

    Figure 24 - Select created contact

    Then the selected contact object will appear in the "Select Recipient" window. Click on "OK" (Figure 25).

    Figure 25 - Selected contact object

    In "Delivery Options" window enable "Deliver messages to both forwarding address and mailbox" option and click on "OK".

    The configuration of the server is complete. I have created a forwarding address for John Smith user, then enabled "Deliver both..." option. With this option both the forwarding and the Exchange e-mail address will receive mails. In this way, if there is an incoming mail, the user will receive it on his e-mail address and his cellphone (Figure 26).

    Figure 26 - Deliver e-mail to addresses

    Now on the client computer go to control panel and select "Mail" menu item (Figure 27).

    Figure 27 - Mail settings

    To add a profile to it, click on "Add..." (Figure 28).

    Figure 28 - Add mail profile

    Provide a name for the profile and click on "OK" (Figure 29).

    Figure 29 - Profile name

    Select "Add a new e-mail account" option and click on "Next" (Figure 30).

    Figure 30 - Add e-mail account

    Next select "Microsoft Exchange Server" and click on "Next" (Figure 31).

    Figure 31 - Exchange e-mail server

    In the next window provide the IP address of the server then a username you wish to use, and click on "Check Name" (Figure 32).

    Figure 32 - Exchange server address and username

    If the data have been checked, the server's IP address will turn into the server's full computer name, and the user's logon name will turn into the full name of the user. These will be underlined (Figure 33).

    Figure 33 - Checked settings

    For a better demonstration I create a profile for the other user, Edward Taylor, on the client computer.

    If it is done, close the "Control Panel" and to test the system I start Microsoft Outlook in "Start" menu (Figure 34).

    Figure 34 - Start Outlook

    Select a profile for login and click on "OK" (Figure 35).

    Figure 35 - Select profile

    After login, click on "New" to send a test message (Figure 36).

    Figure 36 - New e-mail

    Enter the recipient, in our example it will be Edward Taylor, I write a message and click on "Send" (Figure 37).

    Figure 37 - Provide recipient and write e-mail

    After I log into Outlook with Edward Taylor's profile, you can see the received test message from "john smith" (Figure 38).

    Figure 38 - Received e-mail

    Now I compose and send a test message for John Smith as well (Figure 39).

    Figure 39 - New e-mail for John Smith

    After I log into Outlook with John Smith's profile you can see the received test message from "edward taylor" (Figure 40).

    Figure 40 - Received e-mail

    There is a secondary e-mail address assigned to John Smith user so MS Exchange Server 2003 has forwarded the message to that address as well. In this way Ozeki NG SMS Gateway has already sent the SMS message (Figure 41).

    Figure 41 - Sent SMS

    This demonstrated how e-mail to SMS conversion works. Now let's see how SMS to e-mail function works. First you need to add a new user in Ozeki NG SMS Gateway. To do so, click on "Add new user or application" after you log into Ozeki NG SMS Gateway with your username and password (Figure 42).

    Figure 42 - Add new user in Ozeki NG SMS Gateway

    Select "E-mail user interface" user and click on "Install" next to it (Figure 43).

    Figure 43 - Install e-mail user

    Provide a name for this user and click on "OK". Then click on "SMS to E-mail" tab and enable "Enable SMS to E-mail forwarding" option. Then provide data relating to the SMTP server in the following way:

    Sender e-mail address: this will be the sender of the message. In our example it is "".
    SMTP server: The Ip address of the computer where Microsoft Exchange Server 2003 is. In our example it is: "".
    If it is done click on "Recipient" tab (Figure 44).

    Figure 44 - SMTP settings

    Provide the recipient's name: e.g. "" (Figure 45). Now click on "SMTP authentication" tab.

    Figure 45 - Recipient settings

    As MS Exchange requires authentication, enable the following option: "My SMTP server requires authentication". Then provide the sender's username and password. Click on "OK" (Figure 46).

    Figure 46 - SMTP authentication settings

    Now I will simulate an incoming message via SMPP connection (Figure 47).

    Figure 47 - Received SMS

    If you take a look at the installed e-mail user's "Events", it can be seen that it has sent the message (Figure 48).

    Figure 48 - Sent e-mail from Ozeki NG SMS Gateway

    After log into Outlook with Edward Taylor's profile, the received SMS can be seen (Figure 49).

    Figure 49 - Edward Taylor's received e-mail
