System for connecting calls on physically distinct servers on an advanced intelligent network

In a system comprising a plurality of switching systems in a public switched telephone network connected to an advanced intelligent network, said advanced intelligent network including a plurality of servers connected to the switching systems over a plurality of primary rate interface trunks and a control computer connected to said servers, a method for connecting calls on said server comprising the steps of:

• receiving a first call on a first server by way of a primary rate interface;
• receiving a second call on a second server by way of a primary rate interface;
• transmitting a call identification number from said control computer to said first server, said first server associating the call identification number with a code;
• transmitting a designated telephone number to said control computer, said telephone number being a number assigned by the public switched telephone network to said first server, and transmitting said code associated with the call identification number from said first server to the control computer;
• transmitting said telephone number and said code to said second server;
• said second server making a call to said first server using said telephone number to establish a connection between the first and second servers via at least one of said switching systems;
• transmitting said code from the second server to the first server using out-of-band signaling;
• said first server using said code and identifying said call identification number associated with that code;
• said first and second servers connecting said first call and said second call to said connection, respectively, to complete the inter-server bridge connection.
