Abstract
In one particular embodiment, the secure media includes information sent using secure real-time transfer protocol (sRTP). Supplementary services may include call transfers, forwards/redirects, call hold with music on hold (MOH), call hold with no MoH, call resume, call park, call pickup, call blast etc. In a call flow, a call request may be received from a first device for a second device. The call request may include at least one set of keys and be ready for establishment of an sRTP call. It is then determined that a supplementary service is needed for the call request. For example, a supplementary service may indicate that a call redirect to a third device is required. The gateway then facilitates a supplementary service call with the third device. This is facilitated without contacting the first device to generate a second key after receiving the initial call request.
