Inter-Tel (Delaware), Incorporated

Dear Alex:

I am in receipt of your letter of April 3, 2007. I note that prior to my receipt of your letter, I had not been notified of the April 2007 meeting of the Board of Directors of Inter-Tel referenced in your letter and I remain unaware of the exact meeting date in April and time. I believe this is typical of the way that I, as the Company’s founder, largest stockholder and a member of the Board, as well as my two nominees on the Board, have been treated for the past several months.

While I appreciate the Board’s willingness to consider my stockholder proposals as set forth in the preliminary proxy statement I filed with the Securities and Exchange Commission on March 30, 2007, the Board has had well over two months to analyze the proposals which I first made in a letter to the Board on January 19. To date, all that I have heard is rhetoric, which I believe is solely designed to delay the process and to avoid taking any affirmative action to address the issues raised in my proposals, as further evidenced by the failure of the Board to set forth any meaningful plan of action for increasing stockholder value. I disagree with your conclusion that a “proxy contest is simply unnecessary.” A proxy contest is necessary because the Board failed to consider my proposals until after I filed a proxy statement, and I still have not received any written indication that the Board is serious about implementing any of my seven proposals or any written plan of action.

I believe that further rhetoric without action will ultimately jeopardize the interests of all of the stockholders which, as the largest stakeholder in the Company, will adversely affect me as well. Accordingly, I do not intend to withdraw my proposals or my proposed slate of directors

unless the Board puts forth a written plan of action satisfactory to me which either includes my proposals or provides a plan that will provide similar or greater value to the Company’s stockholders.

Sincerely,
/s/ Steven G. Mihaylo
