Device for managing calls on behalf of a plurality of local terminals (T1-T5), this device including: - an interface for communicating with each of said local terminals (T1-T5); - a plurality of client communication modules (CL2-CL5), each being able to set up, through a communication network, with at least one remote terminal (T6-T10), a communication link compliant with a communication service; and - routing means for: - in the case of receipt, by one of the client communication modules, of an incoming call originating from a remote sending terminal, selecting, from among said plurality of local terminals, at least one local terminal able to receive said call and redirecting said call to the interface for communicating with the selected local terminal, for the purpose of setting up, through the client communication module receiving the call, a communication link between said remote sending terminal and the selected local terminal; and - in the case of receipt of an outgoing call request by an interface for communicating with a local sending terminal, identifying a client communication module able to set up a communication channel compliant with a selected communication service and transmitting the request to the identified client communication module, for the purpose of setting up, through the identified client communication module, a communication link, compliant with the selected service, between a remote recipient terminal and the local sending terminal; the call management device being characterized in that it uses, to set up the portion of the communication link between said management device and an arbitrary local terminal from the plurality of local terminals, a single signalling protocol that is independent of the communication service corresponding to the communication link and therefore of the associated client communication module via which this link is set up; the call management device including conversion means for converting first data compliant with a generic transport protocol specific to a type of communication supported by the local terminals into second data compliant with a particular communication protocol of the same type used for a given communication service associated with a client communication module, or vice versa; the generic transport protocol being compatible with the single signalling protocol used. - an interface for communicating with each of said local terminals (T1-T5); - a plurality of client communication modules (CL2-CL5), each being able to set up, through a communication network, with at least one remote terminal (T6-T10), a communication link compliant with a communication service;
