+/**
+ * Register new transport type to PJSIP. The PJSIP transport framework
+ * contains the info for some standard transports, as declared by
+ * #pjsip_transport_type_e. Application may use non-standard transport
+ * with PJSIP, but before it does so, it must register the information
+ * about the new transport type to PJSIP by calling this function.
+ *
+ * @param tp_flag   The flags describing characteristics of this
+ *                  transport type.
+ * @param tp_name   Transport type name.
+ * @param def_port  Default port to be used for the transport.
+ * @param p_tp_type On successful registration, it will be filled with
+ *                  the registered type. This argument is optional.
+ *
+ * @return          PJ_SUCCESS if registration is successful, or
+ *                  PJSIP_ETYPEEXISTS if the same transport type has
+ *                  already been registered.
