A signaling method for use in a communication network, in particular a unified network, for supporting a communication along a communication path ( 12 ) via a plurality of in-path network infrastructure elements ( 6, 8, 10 ) of the network. A service element ( 26, 28 ) of the network which is located off the communication path triggers an in-path network infrastructure element ( 6 ) and the triggered in-path network infrastructure element initiates in-path signaling along the communication path. In particular, the service element may send a message to a terminating end point of the communication, which message is intercepted by the network infrastructure element ( 6 ) closest to the terminating end point, which closest network infrastructure element initiates the in-path signaling.
