Abstract
A method for establishing a synchronous connection between two terminals over an asynchronous communication transport is provided. The method includes receiving, from a first secure terminal, an indication for establishing a connection with a second secure terminal. The indication is received at a first gateway, which then sends the indication to a second gateway. The first gateway negotiates with the first secure terminal to establish a connection with the first gateway. The negotiation is performed without the first gateway communicating with the second gateway or the second secure terminal. A second gateway also negotiates with the second secure terminal to establish a connection with the second gateway. When it is determined that the first secure terminal and first gateway have established a first connection and the second secure terminal and second gateway have established a second connection, a connection between the first secure terminal and the second secure terminal is established through the first gateway and the second gateway.
