| callback_num_atag | Associates a displayable alphanumeric tag with the call-back number. If this parameter is present and there are multiple instances of the callback_num parameter then this parameter must occur an equal number of instances and the order of occurrence determines the particular callback_num_atag which corresponds to a particular callback_num. | 4.8.4.16 |
| callback_num_pres_ind | Defines the call-back number presentation and screening. If this parameter is present and there are multiple instances of the callback_num parameter then this parameter must occur an equal number of instances and the order of occurrence determines the particular callback_num_pres_ind which corresponds to a particular callback_num. | 4.8.4.17 |
| dest_addr_np_country | E.164 information to the operator country code. | 4.8.4.20 |
| dest_addr_np_information | Number portability information for the destination address. | 4.8.4.21 |
| dest_addr_np_resolution | Number portability query indicator. | 4.8.4.22 |
| dest_addr_subunit | The subcomponent in the destination device for which the user data is intended. | 4.8.4.23 |
| dest_network_id | Identification of destination network. | 4.8.4.25 |
