Board of Directors of Inter-Tel, Incorporated
c/o Alex Cappello, Chairman
1615 South 52nd Street
Tempe, Arizona 85281

Dear Members of the Board of Directors:

         I am writing to reaffirm my interest in meeting with the Board of
Directors of Inter-Tel, Incorporated (the "Company"), or its advisors to
discuss a possible all-cash acquisition of the Company led by me, as expressed
in my April 3, 2006 letter to you.

         As you are aware, on Friday, April 7, 2006, as necessitated by the
advance notice bylaw provisions that you adopted on March 29, 2006, I
delivered to the Company an advance notice of business and an advance notice
of director nominations to be brought before the Annual Meeting of
Shareholders scheduled for May 31, 2006. In those notices, I stated, among
other things, that I intended (i) to nominate a slate of three directors
(including myself) for election at the Annual Meeting and (ii) to introduce at
the Annual Meeting several resolutions to be submitted to the vote of the
shareholders, including a resolution urging the Company's Board of Directors
to arrange for the prompt sale of the Company to the highest bidder. I took
this action in order to preserve my ability to communicate directly with the
Company's shareholders and to solicit their support for my proposal to seek a
prompt sale of the Company.

         I continue to believe that the best path forward for the Company's
shareholders is for you to work with me cooperatively to negotiate an all-cash
acquisition of the Company by me, or a higher bidder, and I remain interested
in meeting with the Company's advisors to discuss such a transaction. I
believe that a cooperative process, which would enable me and my financing
sources to gain access to expedited and limited due diligence, would result in
a proposal that is mutually beneficial and could enable us to offer
significantly more value to the Company's shareholders than one without such
access. To expedite this process, I am prepared to sign a confidentiality
agreement containing reasonable provisions, but one





which would not inhibit or preclude my ability to make an offer directly to
the Company or its shareholders or to conduct my proxy solicitation.

         I look forward to hearing from you soon.

Sincerely,

/s/ Steven G. Mihaylo

Steven G. Mihaylo
