          99.1      Press  release  dated  July 21,  2003  announcing  pro-forma
                    results for the second  fiscal  quarter and six months ended
                    June 30, 2003,  and comparing  such results with the results

ITEM 9. REGULATION FD DISCLOSURE

     INFORMATION PROVIDED UNDER ITEM 12 OF FORM 8-K

     On July 21, 2003,  Inter-Tel,  Incorporated  (the "Company") issued a press
release  announcing  pro-forma  results  for the second  fiscal  quarter and six
months ended June 30, 2003 and  comparing  such results with the results for the
second quarter and six months ended June 30, 2002. In this release,  the Company
also indicated that it is increasing its quarterly  dividend to $0.06 per share.
Pursuant to General Instruction B.6 of Form 8-K, this exhibit is not "filed" for
purposes of Section 18 of the Securities  Exchange Act of 1934, as amended,  but
is instead furnished as required by that instruction.  Further,  pursuant to the
Securities and Exchange Commission's Final Rule Release No. 33-8216, the Company
is including the foregoing Item 12 information  under Item 9 because Item 12 has
not yet been added to the EDGAR system.

The press release is furnished as Exhibit 99.1 hereto.

USE OF NON-GAAP FINANCIAL INFORMATION

In  May  2001,  Inter-Tel  entered  into  an  agreement  to  submit  to  binding
arbitration a lawsuit we filed in 1996. The arbitration was completed in January
2002 and, as a result of the  arbitration,  Inter-Tel  received a one-time gross
cash award of $20 million in February 2002.  Direct costs for  attorney's  fees,
expert witness costs,  arbitration  costs and additional  payments and expenses,
totaled  approximately  $4.5 million in 2002,  excluding income taxes, for a net
award of  approximately  $15.5  million.  The  estimated  net proceeds from this
arbitration settlement were approximately $9.5 million after taxes, or $0.37 per
diluted share for the year ended December 31, 2002.

This one-time  litigation  settlement was a  non-recurring,  non-operating  item
included in our GAAP results.  Our management  believes that the presentation of
our  results  on a non-GAAP  basis to  exclude  proceeds  we  received  from the
litigation  settlement  provides investors a more meaningful basis of evaluating
our  performance for the second fiscal quarter and first six months of 2003, and
for comparing our results with prior and subsequent periods.
