                          INDEPENDENT AUDITORS' REPORT

To the Participants and the Plan Administrator of the Inter-Tel, Incorporated
Tax Deferred Savings Plan and Retirement Trust:

We have audited the accompanying statements of net assets available for benefits
of Inter-Tel, Incorporated Tax Deferred Savings Plan and Retirement Trust at
December 31, 2002 and 2001, and the related statement of changes in net assets
available for benefits for the year ended December 31, 2002. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with U.S. generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Inter-Tel,
Incorporated Tax Deferred Savings Plan and Retirement Trust at December 31, 2002
and 2001, and the changes in net assets available for benefits for the year
ended December 31, 2002 in conformity with U.S. generally accepted accounting
principles.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for purposes of additional analysis and is not a
required part of the basic financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management,
and has been subjected to the auditing procedures applied in the audit of the
basic financial statements and, in our opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

TAX DEFERRED SAVINGS PLAN AND RETIREMENT TRUST

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001
--------------------------------------------------------------------------------

(1)  DESCRIPTION OF THE PLAN

          The following description of the Inter-Tel, Incorporated Tax Deferred
     Savings Plan and Retirement Trust (the "Plan") provides only general
     information. Participants should refer to the Plan document for a more
     complete description of the Plan's provisions.

          GENERAL - The Plan is a defined contribution plan covering all
     employees of Inter-Tel, Incorporated and its subsidiaries (the "Company").
     The Plan is administered by the Company. Effective January 1, 2001, an
     employee becomes eligible to participate in the Plan subsequent to the pay
     period in which the employee completes one hour of service. The Plan was
     established on December 1, 1984 and is subject to the provisions of the
     Employee Retirement Income Security Act of 1974, as amended ("ERISA").

          CONTRIBUTIONS - Each year, participants may contribute a percentage or
     dollar amount of their annual compensation to the Plan up to the annual IRS
     maximum through regular payroll deductions. Participants have the
     opportunity to change the previously elected percentage or dollar
     contributions each business day, to be effective at the next bi-weekly
     payroll period. Eligible participants receive a discretionary matching
     Company contribution. For 2002, the Company matched 50 percent of the
     participant's basic contribution limited to six percent of the
     participant's 2002 compensation. At the Company's discretion, it may
     allocate profit sharing contributions at the end of each Plan year
     according to the terms of the Plan.

          PARTICIPANT ACCOUNTS - Each participant's account is credited with the
     participant's contributions, the Company's contributions and an allocation
     of Plan earnings. Allocations are based on participant account balances.
     The benefit a participant is entitled to receive is the participant's
     vested account balance. Participants may elect to have their accounts
     invested in mutual funds or common stock of the Company as offered by the
     Plan, or they may elect to have their accounts invested through individual
     self-directed brokerage accounts.

          VESTING - Participants immediately vest in their voluntary
     contributions plus actual earnings thereon and amounts rolled over from
     other plans into the Plan. Vesting in the Company's matching contribution
     is based on years of service. The employer contribution portion of each
     participant account vests starting the first year of service at a graduated
     amount each year until completing the sixth year of service. After six
     years, the participant is 100 percent vested in the employer contribution
     account.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001
--------------------------------------------------------------------------------

          FORFEITURES - Forfeited balances of terminated participants' nonvested
     accounts are used to reduce future employer contributions. In 2002,
     forfeitures totaled $64,938 and are reflected as a reduction of employer
     contributions receivable and employer contributions at December 31, 2002 in
     the accompanying financial statements.

          PARTICIPANT LOANS - Participants can borrow from their accounts a
     minimum of $1,000, up to a maximum equal to the lesser of $50,000 or 50% of
     their vested account balance. Loan terms range up to a maximum of five
     years, with the exception of loans for the purchase of a primary residence,
     which carry a maximum of up to twenty years. Loans are secured by the
     balance in the participant's account and bear interest at a rate
     commensurate with prevailing rates at the time the loan is made as
     determined by the loan administrator. Principal and interest is generally
     paid ratably through payroll deductions.

          PAYMENT OF BENEFITS - Upon termination of service, a participant may
     receive a lump-sum amount equal to the vested value of his or her account.
     Upon death, disability, or retirement, participants or their beneficiaries
     may elect to receive lump sums or annual installments over a 10 year
     period.

          PLAN TERMINATION - Although the Company intends to continue the Plan
     indefinitely for the benefit of its participants, the Company has the right
     to discontinue its contributions at any time and to terminate or modify the
     Plan, subject to the provisions of ERISA. In the event of termination of
     the Plan, participants will become 100 percent vested in all of their
     accounts.

(2)  SIGNIFICANT ACCOUNTING POLICIES

     The significant accounting policies followed by the Plan are as follows:

          INVESTMENT VALUATION AND INCOME RECOGNITION - The Plan's investments
     are stated at fair value. Securities and mutual funds traded on national
     securities exchanges are valued at the last quoted sales price on the
     principal exchange on which they are traded. Securities, limited
     partnerships and real estate promissory notes for which no price is readily
     available on the valuation date are valued at fair value as determined by
     the Plan Administrator. Participant loans are valued at their outstanding
     balances, which approximates fair value. Purchases and sales of securities
     are recorded on a trade date basis. Interest income is recorded on the
     accrual basis. Dividends are recorded on the ex-dividend date.

          USE OF ESTIMATES - The preparation of financial statements in
     conformity with U.S. generally accepted accounting principles requires
     management to make estimates and assumptions that affect the reported
     amounts of net assets, and the reported amounts of changes in net assets
     during the year. Actual results could differ from those estimates.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001
--------------------------------------------------------------------------------

          CONCENTRATIONS OF CREDIT AND INVESTMENT RISK - The Plan provides for
     various investment fund options, which in turn invest in any combination of
     mutual and other investment funds. Investment securities are exposed to
     various risks, such as interest rate, credit and overall market volatility
     risks. Due to the level of risk associated with certain investment
     securities, it is reasonably possible that changes in risks in the near
     term could materially affect participants' account balances and the amounts
     reported in the statements of net assets available for benefits and the
     statement of changes in net assets available for benefits.

          RECLASSIFICATIONS - Certain amounts in the 2001 statement of net
     assets available for benefits have been reclassified to conform to the
     current year presentation.

(3)  INVESTMENTS

     Investment information is summarized as follows:

(4)  ADMINISTRATIVE EXPENSES

          Substantially all of the Plan's administrative expenses, except for
     record-keeper fees associated with several specific fund expenses and
     special transaction fees, are paid by the Company.

(5)  PARTY-IN-INTEREST TRANSACTIONS

          Certain plan investments are shares of common stock of the Company or
     are funds held and managed by Charles Schwab Trust Company, the asset
     custodian; accordingly, these transactions qualify as party-in-interest
     transactions. Such transactions, while considered party in interest
     transactions under ERISA regulations, are permitted under the provisions of
     the Plan and are specifically exempt from the prohibition of party in
     interest transaction under ERISA. Fees paid and accrued by the Plan to the
     record-keeper for administrative fees amounted to $63,324 for the year
     ended December 31, 2002.

(7)  INCOME TAX STATUS

          The Plan has received a favorable determination letter from the
     Internal Revenue Service dated January 8, 1992 stating that the Plan is
     qualified under Section 401(a) of the Internal Revenue Code (`'the Code")
     and, therefore, that the related trust is exempt from federal and state
     income or franchise taxation. Subsequent amendments have been structured to
     and are intended to maintain the Plan's tax status. Once qualified, the
     Plan is required to operate in conformity with the Code to maintain its
     qualification. The Plan administrator believes the Plan is being operated
     in compliance with the applicable requirements of the Code and ERISA, and,
     therefore, believes that the Plan is qualified and the related trust is
     exempt from federal and state income or franchise taxes..
