There are many seafarers in Sri Lanka who take jobs in the merchant vessels and cruise ships that are operating in the high seas. Mean while there are many other seamen from other countries too are working in the International and costal line operating ships around Asia region. They can call their homes in Sri Lanka through their ship radio's operator or through their deck officers. The ship radio operator will contact a costal radio station and will get the necessary phone connection between the ship phone and the desired phone line.
The phone will give one way connection only through these kinds of cheap connections. The person in the ship has a speaking mic with a press button. When he doesn’t press the button he can listen anything from the other side. Pressing this button he can speak and the person in the other end can listen to the person from the ship. Normally the ship person will finish with the word "Over" and release the button. Then from the other end person can speak and the person from the ship can listen to it through the speaker system.
When the person finished his sentence he should say over and release the button on the mic, so the other person in the land can start to the conversation. Once he finishes the sentence he also must say over. So the person in the ship will press the button in the mic and will start to speak. Like this they have to make the call. So the person in the land must understand that his voice will not reach to the person in the ship when the person in the ship is talking to him.
