You can connect directly to the service provider to make voice calls. If you choose this option, you need to make a contract with your service provider and get a VoIP account, namely a username, a password, a port number and an IP address. Ozeki NG - SMS Gateway sends your message to the service provider using your VoIP account and the service provider forwards the message to the recipient (Figure 1).

2. Using a telephone line adapter

You can connect Ozeki NG - SMS Gateway to the telephone network if you are using a telephone line adapter in three different ways:

Ozeki NG - SMS Gateway is connected to the service provider through a GSM Gateway. The software sends your voice message to the GSM Gateway, which forwards it to the GSM service provider. The service provider will transmit your voice message to the recipient's mobile phone (Figure 2).

2/b Analog phone lines: VoIP to analog telephone adapter

An ISDN Ata is used to connect VoIP and ISDN networks. If you use an ISDN ATA to connect to the telephone network, Ozeki NG - SMS Gateway will forward your voice message to the service provider through the ISDN ATA. Then your message is sent to the recipient by the service provider (Figure 4).

3. Using the corporate PBX

You can use your corporate PBX to connect Ozeki NG - SMS Gateway to the telephone network. This way, you can send voice messages to the different phones attached to the PBX within the office, or you can use the PBX to send messages to a phone outside your private system, using the service provider. If you would like to send voice messages within your private system, you need to add the prefixes of the phones attached to the PBX and the software will send out your messages to the recipients through the PBX.
