21 * @file conversation/test_conversation_api_twocalls.c
22 * @brief testcase for conversation_api.c
24 * This test performs the operations of TWO calls made to a phone
25 * where the phone user picks up one, suspends it, picks up the
26 * second one; eventually, the initiator hangs up, the callee
27 * resumes the first call, and then the initiator hangs up the
