Step 1: Enable voice call support in Ozeki NG SMS Gateway

If you are evaluating Ozeki NG SMS Gateway you can test voice call support immediately, because this features is enabled in the trial version by default.

(When you purchase the Voice Call Addon, you will receive a new license code that unlocks the voice features.)

Step 2: Connect your system to the telephone network

To make voice calls, you need to connect your Ozeki NG SMS Gateway system to the telephone network. This can be done in three ways:

Option #1: You can use a VoIP telephone adapter.

A VoIP telephone adapter is a hardware device that can be connected to your ethernet LAN or to your computer. It makes it possible for Ozeki NG SMS Gateway running on your computer to dial telephone calls. There are VoIP telephone adapters for GSM lines, for standard analog telephone lines and for ISDN lines. (If you don't have a VoIP telephone adapter, you can order one directly from us). When you put this hardware on your Ethernet LAN, it will receive an IP address. You need to configure this IP address in Ozeki NG SMS Gateway to be able to make voice telephone calls through the device.

Option #2: You can use a SIP Account provided by Internet based VoIP telephone provider.

VoIP telephone service providers offer a telephone service over the Internet. They can forward calls to traditional telephone networks and to Internet users signed up to their network. There are many VoIP telephone service providers out there. When you sign up for their service, you will receive a SIP account (an IP address, a username and a password, plus some other details). To make voice calls from Ozeki NG SMS Gateway, you need to configure the SIP account details in the administration screen.

Option #3: You can use your existing office PBX if it is a VoIP system.

If your office has an IP telephone system, you can connect Ozeki NG SMS Gateway to it through the office LAN. Ozeki NG can log in with a SIP account to the PBX and it can make telephone calls just like any other office desktop phone would. This is a good choice if you have already invested in IP telephony, because in this case you don't need to have a dedicated telephone line for outbound voice telephone calls made from Ozeki NG SMS Gateway.

Step 3: Configure the Voice call feature of Ozeki NG SMS Gateway


Once you have decided which option to use to connect to the telphone network you are ready to configure Ozeki NG SMS Gateway to make voice calls. The Ozeki NG Voice call features is based on the SIP Voice over IP protocol (VOIP). To be able to make voice calls, you need to login as admin and install a "VoIP Autodialer" service provider connection on the graphical user interace of the software. This service provider connection can be installed just like any other service provider connection.

A SIP account enables you to connect Ozeki NG SMS Gateway to the IP telephone service.
