A client or user equipment (“UE”) that initiates a plurality of calls using encapsulated media, in response to a first tunnel creation request, from an application associated with a first call, initiates the first call by creating a first tunnel between the client and a server. The UE transmits the encapsulated media associated with the first call over the first tunnel. The UE, in response to a tunnel termination request, from the application, associated with a termination of the first call, waits for an expiration of a predefined persistence period. The UE, in response to a second tunnel creation request, from the application associated with a second call, before the expiration of the predefined persistence period, initiates the second call using the first tunnel. The UE then transmits the encapsulated media associated with the second call over the first tunnel.
