CHIEF INFORMATION OFFICER
FROM: Pamela J. Gardiner /s/ Pamela J. Gardiner
Deputy Inspector General for Audit
SUBJECT: Final Audit Report - Monitoring of Long Distance and Cellular Telephone Costs Continues To Need Improvement
This report presents the results of our review of the Internal Revenue Service’s (IRS) management of telecommunications costs related to long distance telephone calls, calling cards, and cellular telephones. In summary, IRS management has initiated numerous corrective actions since 1993 to improve internal controls in the telecommunications area. However, controls over its telecommunications costs, which were deemed a material weakness by the IRS 7 years ago, still need improvement. Specifically, IRS management needs to improve the monitoring of long distance, calling card, and cellular telephone charges because many of the corrective actions have not been fully implemented or have not been effective in controlling the costs.
IRS management provided an adequate, detailed response to our draft report and is taking actions to address the telecommunications cost issues. Management’s complete response to the draft report is included as Appendix VII.
Our recommendations will provide measurable benefits to tax administration in the form of protection of resources of $1,092,200. These benefits were previously discussed with Telecommunications Division management. Appendix IV of this report provides a detailed description of these benefits, which will be included in our Semiannual Report to the Congress.
Copies of this report are also being sent to the IRS managers who are affected by the report recommendations. Please contact me at (202) 622-6510 if you have questions or Scott E. Wilson, Assistant Inspector General for Audit (Information Systems Programs), at (202) 622-8510.

The Internal Revenue Service (IRS) is completing the transition of its Federal Telecommunications System (FTS) long distance telephone service from AT&T to Sprint and is scheduled to implement the Telecommunications Asset Tool (TAT) in July 2001 for monitoring and tracking telecommunications assets. The IRS is also in the process of drafting national guidelines to centralize the issuance and usage of cellular telephones.
The overall objective of this audit was to determine whether the IRS is effectively managing the telecommunications costs related to FTS long distance calls, calling cards, and cellular telephones. We also followed up on related corrective actions contained:
Results
The IRS began work to improve controls in the telecommunications area based, in part, on our prior audit findings reported over 7 years ago. Although many corrective actions have been initiated to improve telecommunications controls, the reported issues still exist as planned actions were not completed or were not effective due to numerous reorganizations and unclear program accountability. Improving telecommunications controls would provide additional assurance that the planned Fiscal Year (FY) 2001 FTS long distance and cellular telephone service expenditures of over $20 million are properly spent for these services.
Long Distance Telephone Calls Are Not Reviewed
In the two prior audits in 1993 and 1998, weaknesses were identified in the IRS’ process for reviewing telephone call reports. Since then, the IRS has been involved in the development of several different computer systems that were to be used for review purposes to better control long distance telephone costs. However, reviews have not been conducted on a regular basis because of delays in implementing system software and the lack of fully approved detailed review procedures.
Our analysis of the long distance telephone billing information showed that, for Calendar Year 2000, over 17,000 telephone calls costing approximately $1,092,200 for 53,439 hours of usage would have been identified as questionable charges by IRS management had they reviewed the information using the four original IRS-approved review criteria. Additional analysis showed that over 842,000 telephone calls costing $743,000 for 215,144 hours of usage would have been identified as questionable charges by IRS management had they reviewed the information using the six revised IRS-approved review criteria.
In addition to the cost of the questionable telephone calls, there is the potential for lost staff time on unauthorized or unnecessary telephone calls. Furthermore, telephone bills are not being reviewed for accuracy, and controls over calling cards have not been fully implemented.
Controls Over the Cellular Telephone Inventory and Costs Are Not Effective
Cellular telephone control weaknesses and the lack of national guidelines to control the acquisition or use of cellular telephones were reported in the prior audit in 1993. The IRS agreed to monitor and control cellular telephone usage and maintain an accurate inventory. However, national guidelines have not been developed nor an accurate inventory maintained. As a result, there is no assurance that the cellular telephone program, which has recently seen extensive growth, is managed efficiently as charges have been as much as $1,000 for 1 month’s telephone charges for a single cellular telephone.
Summary of Recommendations
The Deputy Commissioner for Modernization & Chief Information Officer should ensure that guidelines and procedures for reviews and billing verification of long distance telephone charges and for cellular telephone issuance and usage are developed, implemented, and monitored. In addition, controls should be implemented to ensure calling cards are periodically inventoried and issued only to authorized IRS employees.
Management’s Response: IRS management will implement guidelines and procedures for reviews of long distance telephone charges using approved criteria; implement the TAT with procedures for verifying long distance billing; inventory calling cards annually; and implement guidelines and procedures for cellular telephone issuance, usage, and monitoring.
Management’s complete response is included as Appendix VII.
Office of Audit Comment: In the Corrective Action Monitoring Plan for recommendation #2, IRS management provides that a TIGTA audit of the TAT was requested. While we included an audit of the TAT in our FY 2002 Annual Audit Plan, TIGTA audits do not replace the need for management to monitor the corrective actions.
The overall objective of this audit was to determine whether the Internal Revenue Service (IRS) effectively manages telecommunications costs related to Federal Telecommunications System (FTS) long distance calls, calling cards, and cellular telephones. To accomplish our objective, we reviewed the:
Audit work was conducted in the National Headquarters and the Tennessee Computing Center during November 2000 through May 2001. The audit was scheduled as part of the Treasury Inspector General for Tax Administration’s (TIGTA) Fiscal Year (FY) 2001 Annual Audit Plan and was performed in accordance with Government Auditing Standards.
Details of our audit objective, scope, and methodology are presented in Appendix I. Major contributors to this report are listed in Appendix II.
In September 1993 and March 1998, the IRS’ Internal Audit function (now TIGTA) reported that the IRS was not verifying the accuracy of FTS bills, unauthorized telephone calls were not being detected, and the controls over calling cards and cellular telephones were inadequate.
In 1994, the IRS categorized the internal controls over its telecommunications costs as a material weakness as part of the Federal Managers’ Financial Integrity Act (FMFIA) internal control assessment process. Since that time, the IRS has prepared numerous action plans and planned over 30 specific corrective actions to improve the controls over these costs. Planned corrective actions included:
In November 1999, the IRS designated the Chief, Information Technology Services, as the official responsible for the ownership, management, and control of all Telecommunications assets. In FY 2001, the IRS budgeted over $20 million for FTS long distance and cellular telephone service.
Since late 1993, IRS management has initiated numerous corrective actions to improve controls in the telecommunications area; however, the monitoring of FTS long distance and cellular telephone charges continues to need improvement because many of the corrective actions have not been fully implemented or have not been effective in controlling these costs due to numerous reorganizations and unclear program accountability. Specifically, we determined that IRS management has not yet:
In November 2000, Telecommunications Division management made an internal assessment of the IRS’ status in addressing the material weaknesses regarding internal controls over its telecommunications costs. This assessment confirmed the results of our current review and reported that after nearly 7 years of attempting to improve controls in the telecommunications area, the IRS still does not have:
Until the IRS corrects these longstanding issues, there is no assurance that expenditures for long distance and cellular telephone costs are accurate and necessary.
Long Distance Telephone Calls Are Not Reviewed
Various laws require federal government managers to maintain controls over the financial resources and assets of their agencies. For example:
To comply with the various requirements to maintain controls over telecommunications resources and assets, the IRS has implemented several initiatives based partially on the 1993 and 1998 Internal Audit reports. For example, the IRS’ Billing Analysis Reporting Tool provided for the review of FTS long distance telephone charges. However, several controls still need improvement as described below.
Questionable telephone calls are not being identified
In 1994, the IRS categorized the internal controls over its telecommunications costs as a material weakness as part of the FMFIA process. Since that time, the IRS has been involved in the development of several different computer systems that were to be used to better control long distance telephone costs, including calls made from the office or with calling cards. The various systems include the following:
In December 1998, management revised the four criteria into six criteria (see Appendix VI for the revised criteria) and presented the revised criteria to the National Treasury Employees Union (NTEU) for approval. IRS personnel were told not to generate or review any reports using the revised criteria until the NTEU approved the criteria.
When the IRS personnel stopped generating the reports based on the revised criteria, they also stopped regularly generating the reports on the four original criteria. As of May 9, 2001, IRS management had not received a response from the NTEU and IRS personnel were not generating any reports on a regular basis to identify potential telephone misuse.
Although the IRS has obtained several tools to help monitor long distance telephone costs, there were no regular reviews performed of these expenses due to the delays in implementing the software tools and the lack of detailed review procedures agreed to by the NTEU.
To determine the effect of the lack of monitoring the long distance costs, we reviewed the telephone billing information for March through August 2000 using both the four existing and six proposed criteria. Details of each of these reviews are contained in Appendices V and VI. Based on these reviews, we estimated the potential number of questionable calls and the costs for both sets of criteria for the remaining six months of Calendar Year (CY) 2000. See Appendix IV for the questionable telephone call estimate details. In summary, based on the results of our reviews and estimates, we found that there were:
In addition to the cost of the telephone calls, there is also the potential of lost staff time on unauthorized or unnecessary telephone calls. During March through August 2000, there were 31,529 hours spent on calls meeting the 4 criteria and 126,935 hours spent on calls meeting the 6 criteria. We also estimated, for the remaining 6 months of CY 2000, that 21,910 hours may have been spent on calls meeting the 4 criteria and 88,209 hours may have been spent on calls meeting the 6 criteria.
Based on our March through August 2000 analysis, had management reviewed the call information, the following examples of questionable telephone calls could have been identified and resolved:

Billing verification is not being performed
In September 1993, the IRS’ Internal Audit function (now TIGTA) reported that the IRS was not verifying FTS billing charges in part because it had no national billing verification procedures. IRS management agreed to develop and implement billing verification policies and procedures using the BART. Although the BART implementation was completed in March 1998, a billing verification capability was never developed and implemented. Billing verification capability was also not provided when the SPIDR system became operational in March 2001.
IRS Telecommunications Division management attributed non-development of a billing verification process to the IRS’ new way of doing business, which involves the centralization of all resources and the replacement of the SPIDR with the TAT. The IRS’ current contract for the development of the TAT includes the development of procedures for reconciling FTS bills.
Until the Telecommunications Division adequately addresses the billing verification control weakness, the IRS is subjecting approximately $20 million for FTS long distance telephone service to potential overbilling.
Calling card inventory is not being performed
The lack of effective calling card inventory controls was reported in September 1993 by the IRS’ Internal Audit function (now TIGTA). In October 1993 and July 1994, the IRS established inventory databases for the AT&T calling cards and Sprint FONCARDs, respectively. The IRS committed to conducting annual inventories; however, only one inventory has been conducted during the past 7 years. Therefore, the IRS has no current inventory of who has been issued the 35,000 AT&T federal calling cards that had $2,167,493 in charges in FY 2000. Without an accurate calling card inventory, the IRS may not be able to trace identified questionable or abusive calls to the employees who made the calls.
The IRS’ change in FTS contractors from AT&T to Sprint that began in January 2000 has prompted the issuance of Sprint FONCARDs to replace all AT&T calling cards. The AT&T calling cards are scheduled for mass cancellation after nationwide rollout to the Sprint FONCARD is completed.
Employee applications for FONCARDs are being processed through an Intranet application and paper forms. The application process requires two levels of managerial approval. There were a few instances where non-managerial employees registered as managers. IRS managers identified these instances and the incorrect applications were deleted. The employees were instructed on how to correctly apply for the FONCARD. Management advised that the Intranet application process is being revised.
Telecommunications Division management plans to implement new calling card procedures including:
Management advised that these procedures were implemented as of June 1, 2001.
Recommendations
The Deputy Commissioner for Modernization & Chief Information Officer should:
Management’s Response: IRS management will implement guidelines and procedures for reviews of long distance telephone charges using approved criteria. The Telecommunications Division is negotiating with the NTEU on seven review criteria. Also, management has drafted an Employee Informational Guide and Manager Informational Guide and is preparing an implementation plan and distribution procedures for exception reports.
Management’s Response: Telecommunications Division is implementing TAT Release 3 (Financial Module), which will validate services received against monthly call detail data. The TAT Release 4 (Billing Verification Module) functionality will include procedures for reviewing vendor long distance billing data and provide a variety of summary, detailed, and exception reporting. In addition, management requested a TIGTA assessment of the TAT after Release 3 (Financial Module) is operational in December 2001 as the monitoring process for the corrective action.
Office of Audit Comment: While we included an audit of the TAT in our FY 2002 Annual Audit Plan, TIGTA audits do not replace the need for management to monitor the corrective actions.
Management’s Response: The Telecommunications Division will inventory calling cards annually.
Controls Over the Cellular Telephone Inventory and Costs Are Not Effective
Federal government managers are required to maintain controls over the financial resources and assets of their agencies. The FMFIA requires agencies to establish and maintain adequate internal control systems. The OMB Circular A-123, Management Accountability and Control (revised June 1995), further requires agency heads to provide reasonable assurance that resources are protected against waste, fraud, abuse, mismanagement, and misappropriation.
Cellular telephone control weaknesses and the lack of national guidelines to control the acquisition or use of cellular telephones were reported in September 1993 by the IRS’ Internal Audit function (now TIGTA). The IRS responded that it was going to monitor and control cellular telephone usage, establish an accurate inventory, and update the inventory as changes occurred.
The IRS is in the process of drafting national guidelines to centralize the issuance and usage of cellular telephones. The IRS also conducted a cellular telephone inventory in July 1994; however, no inventory has been conducted since that time and the corrective actions agreed to have not been completely implemented.
Although the IRS does not have a national inventory of all cellular telephones issued to its employees nationwide, cellular telephone coordinators and a Service Center Operations representative provided the auditors with information showing that as of December 2000, the Washington, D.C. Metro Area had 801 cellular telephones and the 10 Service Centers had 173 cellular telephones. The explosive growth of the cellular telephone program is illustrated in the following table showing the growth experienced by the Washington, D.C. Metro Area over the past three fiscal years.

We also determined that the IRS continues to issue cellular telephones without having consistent nationwide practices and does not have approved policies and procedures for managing and monitoring the associated inventory and costs. There is also no policy defining who is authorized to get a cellular telephone, and only managerial approval is required. In addition, there is no uniform policy requiring managers to periodically review the business need for employees’ cellular telephone calls and initiate corrective actions where warranted. As a result, the IRS may be incurring additional costs because:
Only one of the three offices reviewed requires employees to validate their monthly cellular invoices for accuracy and reimburse the IRS for any personal calls. Although $2,300 of this office’s cellular telephone costs of $447,000 were reimbursed by employees in FY 2000, there were no managerial reviews of the cellular invoices to assure there was a business need for the calls and the accuracy of the reimbursements.
The following table provides three examples of exorbitant cellular telephone charges in the first month of usage by new cellular telephone users. Revising the employee’s cellular telephone plan in the second month resulted in a significant cost reduction.

Telecommunications Division management informed us that the first month’s bills were high because new users were assigned an economically priced basic rate plan with a low number of minutes without attempting to determine their planned calling needs.
Cellular telephones are issued to new users based on a manager’s approval. However, there are no national guidelines that define valid business needs that warrant a cellular telephone.
In addition, cellular telephones may be retained by users who no longer have a business need because there is no requirement for managers to periodically re-certify an employee’s need. For example, management advised that at the end of the Year 2000 (Y2K) project, a significant number of the personnel who worked on the Y2K project were allowed to keep their cellular telephones without re-certification based on their new assignment. The cost of all Y2K cellular telephones for FY 2000 was approximately $73,500.
We reviewed three offices and identified different practices when assigning new users to a cellular telephone plan. The practices followed were:
In addition, only one of the three offices issued local guidelines explaining appropriate use of cellular telephones. These guidelines provided that cellular telephones:
Although these IRS offices employed some local policies and procedures to help monitor cellular telephone costs, there were no consistent nationwide practices or requirements because the cellular telephone program has not been centralized nor a manager assigned responsibility for the program’s effectiveness. Without consistent policies and procedures for managing the cellular telephone program costs and inventory, the IRS will continue to be at risk of excessive charges.
In its efforts to resolve the reported cellular telephone program control weaknesses, the Telecommunications Division is considering a best practice from another federal agency. The best practice involves reimbursing personal cellular telephone users for official government business calls in lieu of providing those users with a government cellular telephone. According to the IRS Business Performance Review dated February 21, 2001, the IRS plans to pilot the best practice in the Washington, D.C. area.
Recommendations
The Deputy Commissioner for Modernization & Chief Information Officer should:
Management’s Response: The Telecommunications Division will develop and issue guidelines for cellular telephone usage and establish a centralized authority to ensure cellular telephone procurements and usage comply with the guidelines. The Telecommunications Division also began design of a website to provide information about available services and equipment, to process requests for new service and renewal service, and to maintain an inventory. Also, the Telecommunications Division will ensure that users are on the right billing plan.
Management’s Response: The Telecommunications Division will conduct an annual inventory of cellular telephones. In July 2001, the Telecommunications Division issued a Request for Information to the industry for off-the-shelf software that will assist in tracking inventory, tracking usage, and ensuring users are on the correct billing plan. With inventory tracking software, the Telecommunications Division may not need centralized purchase of cellular telephones to provide an annual inventory.
Internal controls over telecommunications costs have been categorized as an FMFIA material weakness since 1994. The IRS has prepared numerous action plans and initiated several corrective actions to improve the controls over these costs. However, controls over long distance charges, calling cards, and the cellular telephone program continue to need improvement because many of the corrective actions have not been fully implemented or have not been effective in controlling these costs. Until the IRS corrects these longstanding issues, there is no assurance that expenditures for long distance and cellular telephone costs are accurate and necessary.

Type and Value of Outcome Measure:
Methodology Used to Measure the Reported Benefit:
March through August 2000 was the 6-month period immediately preceding the beginning of the audit for which detailed billing information was available for review. Therefore, we used this time period for our billing information analysis. We also estimated the results of our March through August analysis over the remainder of Calendar Year (CY) 2000 based on the total number of calls for the year. We assumed that the rate of questionable calls for the estimated 6 months would be the same as the rate of questionable calls for our March through August review period.
We reviewed AT&T long distance telephone call and calling card billing information provided to us via the Internal Revenue Service’s (IRS) Billing Analysis Reporting Tool (BART) Intranet website for the months of January through December 2000. The total number of calls for CY 2000 was 27,902,233. There were 16,431,989 (59 percent) calls billed during the period of March through August 2000 and 11,470,244 (41 percent) calls billed during the other 6 months of CY 2000 (i.e., January, February, and September-December). We analyzed the billing information for March through August 2000 by applying the four original IRS-approved review criteria and the six revised IRS-approved review criteria.
