Abstract
A bridge connection is made between interfaces on physically distinct telecommunication servers such that the two ends of the bridge can be used to connect existing calls that are terminated on each of the servers. To provide the bridge connection, a call using a standard outgoing T1 trunk on one of the servers is made through the public switched telephone network (PSTN) to an incoming T1 trunk on the other server. The servers reserve a special directory number for such calls. When a bridge connection is required one of the servers is queried for its special directory number. The other server is then instructed to make a call to that number. When the called server recognizes the incoming call as using its special number, it answers the call. The calling server then outpulses information needed by the called server to associate the bridge connection with the pending action. In this manner, calls terminating on distinct servers can be connected without the need for additional hardware.
