||Do I need Internet connection to
operate Ozeki NG SMS Gateway?|
No, if you connect to the mobile
network through GSM/GPRS modem(s).
Yes, if you connect to the mobile network
through IP SMS connections.
||Do I need a public IP
No, you do not.
Ozeki NG can be operated in your LAN. It does not require any public IP
address. The only case you need a public IP address if you will use IP SMS
connection (SMPP, CIMD2, UCP, HTTP, etc.) to connect to your SMS service
provider over the Internet. For IP SMS connections, in most cases,
a dynamic public IP address will work. In some cases your IP SMS service
provider will require you to use a fix public IP address.
You will also need a public IP address if you want to provide SMS service to
||Do I need a fix IP address for the
It depends on how do you want to use the software.
If you wish to use the software in your office, or in your organization over
the LAN, you don't need a fix IP address for the SMS Gateway. In this case a
dynamic IP address assigned to your system through DHCP can be used. In case
you wish to provide an SMS service over the Internet, you will need one.
||Can I use a leased line connect to
my mobile operator, instead of an Internet connection?|
Yes. A dedicated leased line is better, because it is more secure then an
If your mobile network operator or SMS service provider gives you the option to
connect to the SMSC through a leased line, take this option. It is often a more
reliable and a more secure connection method, then an IP SMS connection operated
over the Internet.
||How much bandwidth do I need on my
For an IP SMS connection minimum 64kbps is needed. Concerning connection
methods, all internet connection methods, such as ADSL, CableTV, ISDN, T1, E1
can be used.
Bandwidth represents the capacity of the connection. The greater the capacity,
the more likely that greater performance will follow, though overall performance
also depends on other factors, such as latency. In terms of mobile messaging,
the network bandwidth determines the speed you can use to send and receive SMS
messages over IP SMS connections. An average SMS message takes about 1 kilobyte.
the network bandwidth you need, you must estimate the average SMS traffic and
you must multiply it by 1 Kbyte. This way you can calculate the estimated
||Can I use a Virtual Private Network
Yes. A VPN connection is great, because it is more secure then an Internet
If you connect your SMS Gateway to a mobile network operator or to an SMS
service provider over the Internet, it is recommended to use a virtual private
network (VPN) connection. A VPN connection gives you encryption, which means
more security. To setup a VPN connection, VPN routers or software VPN
implementations can be used. You can use PPTP or L2TP to setup the VPN channel.
||My Internet connection is not
reliable. Will this be a problem?|
No, it will only cause temporary outages.
You need internet connection only if you want to send SMS messages over an
IP SMS connection. If the Internet connection brakes it should not be a problem,
because the software will store the messages and try to send them when the
connection comes back up.
If you send your SMS messages over a GSM modem, you don't even need any Internet
To improve reliability, you can add a GSM modem for backup purposes, and in case
the Internet connection brakes, it can take over. To achieve this you need to
configure backup SMS routing in Ozeki
NG SMS Gateway.
||What kind of communication ports
and protocols are used? Should I open any ports on my firewall?
The software listens on TCP Ports 9500-9503. All
ports can be blocked on your firewall.
TCP Port 9500 (protocol SMPP), provides SMPP client connectivity
TCP Port 9501 (protocol HTTP), is used for Administration (HTTP interface for
TCP Port 9502 (protocol TCP/HTTP), is used by .NET Remoting client
TCP Port 9503 (protocol HTTP), is used by ParlayX webservice client
||I am interested in installing your
SMS Gateway and integrating
it with a web site. I am going to host the website in the US however the
gateway has to be locally in Ireland. Does the g/way require
a fixed IP address or is there any way dynamic address can
be used and how?|
Whether you need a fix IP address depends on the method you will use to
integrate the gateway with the website.
There are three popular ways to integrate SMS functionality into a website.
The most popular option is to setup an
SQL to SMS gateway configuration.
This configuration is a good choice if your website has a database, because you
can setup the Ozeki software to connect to this database to provide sms sending
and/or sms receiving functionality. If you use
an SQL to SMS gateway configuration
you don't need a fix IP address for the SMS Gateway in Ireland.
The second option is to use the built in HTTPClient user of Ozeki NG SMS
Gateway. In this case if an SMS arrives to the system from a cellphone, the
Ozeki software will call a predefined URL to pass the incoming message to
the website. For outgoing messages the Ozeki software can periodically
download a webpage to look for SMS messages that need to be sent. For this
(HTTP Client) option you don't need a fix IP address for the SMS Gateway in
The third option is based on the built in HTTP Server of Ozeki NG SMS Gateway.
If you want to send an SMS from your website, and you want to pass this
SMS using an HTTP request to Ozeki NG, you can use the
HTTP SMS API
provided by the software. If you use the
HTTP SMS API
over the Internet you will need a fix IP address.
||Ozeki NG SMS Gateway uses
the http://127.0.0.1:9501 address. Can I change this to my IP address,
so I can access it on my LAN or over the Internet?
Yes, you can change the 127.0.0.1 to point to your LAN or public IP address
The IP address 127.0.0.1:9501 is not ours. This IP address allways points to
the local computer you are working on. Every computer has two IP addresses
the local 127.0.0.1 and a public IP address. The Ozeki software installed on
your computer can be accessed on both IP addresses.
For example if the public IP address of your computer is 192.168.1.100, you
can access your Ozeki NG SMS Gateway service at http://192.168.1.100:9501
To sum it up you can change the 127.0.0.1 ip address to your computers IP
