VoIP gateways are devices that take care of interworking the new emerging VoIP networks with the existing legacy telecommunication networks. The efficient control of such gateways is a key prerequisite for a successful deployment of VoIP. Currently solutions are based on protocols like Megaco/H.248 and SCTP, designed for controlling logical decomposed gateways. Unfortunately not all gateways support decomposition. This paper proposes a technique for controlling “non-decomposable” gateways, based on a modification (bias) of the Megaco control model for allowing signalling handling. The basic concepts are illustrated, giving hints for design. The limitations and drawbacks are also discussed
