Claim:
A method for establishing a coordination connection between a first and a second control center for carrying out services in an intelligent telecommunications network, the first and the second centers each being capable of processing in an autonomous manner a first and a second service request, respectively, and the network comprising, in addition to communication channels used to establish telecommunications connections between various terminals which are connected to the network, communication channels which are reserved for conveying call control signals for controlling the establishment, the modification and/or the release of each telecommunications connection in this network, this method comprising a phase for processing a call which is initiated each time a call is transmitted by a client and which comprises a step for establishing the coordination connection using an address of at least one of the two centers so that these centers can coordinate their respective operations for processing the first and second service requests from the client wherein: in that one of the centres transmits its address to the other center by inserting this address in one of the call control signals transmitted to the other center, and in that the center having received the address inserted in a call control signal establishes the coordination connection by using communication channels which are separate from those used to convey the call control signal in which the address of one of the centers is inserted.
