A method of establishing a communication with a mobile terminal configured for use in a mobile telecommunications network, the network including at least two different subsystems, the method including: receiving a voice communication request in accordance with a first subsystem, at the mobile terminal; determining if conditions associated with the mobile terminal are compatible for implementing a voice call in accordance with the first subsystem; and where conditions arc determined not to be compatible, sending a relevant response. The relevant response may be a request to reattempt the voice communication in accordance with a circuit switched subsystem. Alternatively, the relevant response may be a request to establish a new communication in accordance with a circuit switched subsystem.
