+ * @brief testcase for conversation_api.c
+ *
+ * This test performs the operations of TWO calls made to a phone
+ * where the phone user picks up one, suspends it, picks up the
+ * second one; eventually, the initiator hangs up, the callee
+ * resumes the first call, and then the initiator hangs up the
+ * second call.
