Board of Directors of Inter-Tel

(Delaware), Incorporated

c/o Alex Cappello, Chairman

Tempe, Arizona 85281

Dear Members of the Board of Directors:

I am extremely disappointed with the decision of the Special Committee of the Board, without consultation of the full Board, on Friday to postpone the Special Meeting of Stockholders to vote on the proposed buyout by Mitel. Given the substantial public attention received by this transaction over the past two months, I believe stockholders have had sufficient time and information to evaluate the deal in light of the recapitalization alternative I presented and should have been permitted to determine the fate of their investment. The postponement of the vote will subject stockholders to several more weeks of uncertainty and potential exposure resulting from the Company’s current situation. Furthermore, I am also distressed by the Board’s decision to cite uncertainties in the debt markets as a reason for the postponement without consulting RBC Capital Markets, who advised me as recently as Friday that the current events in the debt markets would not impede the execution of its committed financing.

As the Company’s founder and largest stockholder, I am conflicted by my confidence in the Company’s potential for growth and competitiveness, and my concern as to whether the Company’s current leadership has the vision and direction to achieve these ends. In light of these concerns, and with the goals of protecting my investment and providing greater certainty to stockholders, I respectfully request that the Board immediately implement the following proposals:

1. Reduce the size of the Board from eleven to six members consisting of Dr. Anil K. Puri, Kenneth L. Urish, Steven G. Mihaylo and three persons designated by the current Board;

2. Appoint me as Chairman of the Board;

3. Appoint me as interim Chief Executive Officer of the Company until a qualified candidate can be found;

4. Hire an executive search firm to find a Chief Executive Officer suitable to a majority of the newly constituted Board; and

5. Disband the current Special Committee of the Board and form a new Special Committee of the Board, consisting of a majority of my director nominees, issued with an immediate directive to implement my recapitalization proposal unless a superior proposal emerges prior to implementation of the recapitalization.

If these proposals are implemented by the Board, I will withdraw my proxy statement with respect to the 2007 Annual Meeting of Stockholders. Given that the deadline for me to submit advance notice of business with respect to the 2007 Annual Meeting of Stockholders is fast approaching, I respectfully request the Board to notify me of its determination regarding the above proposals no later than 12:00 pm PDT on Thursday, July 5, 2007. I look forward to working with the Board towards the implementation of the above stated proposals and leading the Company with a renewed focus on growth, value and transparent governance.

Sincerely,

/s/ Steven G. Mihaylo

Steven G. Mihaylo
