Patent ID: 8705566

Claim:
A method for initiating a call in a communication network between a first signaling entity and a second signaling entity each connected to a node and the nodes connected to a network wherein communications between the signaling entities and the nodes is conducted using a first protocol and communications are carried over the network using a second protocol, the first protocol being different than the second protocol, comprising: sending a request for call setup using the first protocol from a first signaling entity to a first node; converting the request for call setup from the first protocol to the second protocol in the first node; sending the call setup request converted into the second protocol from the first node via a network to a second node that is connected to a second signaling entity; converting the call setup request received from the first node from the second protocol to the first protocol in the second node; establishing a separate connection between the first node and the second node over which communications are sendable using the first protocol; the second node requesting data from the call setup request in the first protocol sent by the first signaling entity to the first node from the first node via the separate connection; the first node sending information concerning the data from the call setup request in the first protocol sent by the first signaling entity to the second node via the separate connection; and transmitting messages between the first node and the second node via the separate connection using the first protocol.
