Bus connection set up and tear down

In a voice processing system having:

• a voice application, a bus over which two voice channels are connected;
• and at least two adapter ports, each port for connecting a channel to the bus;
• a method for requesting the closing a bus connection between two voice channels, said method comprising:
• associating the channels with a connection;
• associating the connection with connection details including the adapter ports involved in connecting the channels to the bus and a security token for the connection;
• associating each adapter port with a connection and the security token for that connection;
• receiving from a first adaptor port (i) an indication that its channel has been disconnected and (ii) the security code associated with the first adaptor port;
• determining the connection associated with said first adaptor port and the second adapter port associated with the connection;
• comparing the security token from the first adaptor port with the security token from a second adaptor port;
• disconnecting the second adaptor port from the bus if the security tokens match;
• whereby the voice application does not need to take any further action to disconnect the second port from the bus as such action is initiated in a secure fashion by the first port.

In a voice processing system having a bus over which voice channels are connected;

• more than one adapter port, each port for connecting a voice channel to the bus;
• a voice application for requesting the opening or closing a bus connection between two voice channels, a bus connection controller comprising:
• means for associating the channels with a connection;
• means for associating the connection with connection details including the adapter ports involved in connecting the channels to the bus and a security token for the connection;
• means for associating each adapter port with a connection and the security token for that connection;
• means for receiving from the first adaptor port (i) an indication that its channel has been disconnected and (ii) the security token associated with the first adaptor port;
• means for determining the connection associated with said first adaptor port and the second adapter port associated with the connection;
• means for comparing the security token from the first adaptor port with the security code from the second adaptor port;
• means for disconnecting the second adaptor port from the bus if the security tokens match;
• whereby
• the voice application does not need to take any further action to disconnect the second port from the bus as such action is initiated in a secure fashion by the first port.
