Zusammenfassung:	A telecommunications network has a packet switched domain for handling packet based calls and a circuit switched telephony domain for handling circuit switched calls. A node (230) of the packet switched telephony domain decides whether to terminate a call to a user equipment (10) using a packet based connection to the user equipment (10) or using a circuit switched connection to the user equipment (10). In response to deciding to terminate the call using the circuit switched connection, the node (230) sends, to a further node (240) controlling routing of calls between the packet switched telephony domain and the circuit switched telephony domain, an indication (408) that services related to the call are controlled in the packet switched telephony domain. In accordance with the indication, the further node (240) may then adapt its control signalling with respect to a node (320) of the circuit switched telephony domain.
