A plurality of service facades are used to expose the capabilities of an underlying telecommunications network in different ways. Each service façade provides a different interface to access a set of functions of the telecom network. The service facades can be accessed by client applications residing externally with respect to the telecom network. The client applications can invoke a particular service façade to send a message to the network and the invocations can be translated to the native protocols used by the resources in the telecom network to carry out the request. The service facades can be deployed on a service access gateway to the telecom network and can include a simple object access protocol (SOAP) façade, a representational state transfer (REST) façade, a service oriented architecture (SOA) façade and a native façade.
