A system for processing a call between a mobile services switching centre (MSC) and a gateway mobile switching centre (GMSC) includes a first alternative gateway unit (ANG) being connected to the mobile services switching centre and a second alternative gateway unit (ANG) being connected to the gateway mobile switching centre. A call which is to be processed via an alternative network (AN) is processed directly between the alternative gateway units (ANG). The alternative gateway units (ANG) include means for performing speech and data coding and means to transmit and receive a call to be able to process the call directly via the alternative network, e.g. a Voice-over-IP network.
