LETTER TO MAGICJACK VOCALTEC, LTD'S BOARD

June 20, 2017

Mr. Izhak Gross, Chairman
Mr. Don Carlos Bell III, President and CEO Mr. Richard Harris, Director
Mr. Alan Bradley Howe, Director
Ms. Tali-Yaron Elder, Director

magicJack Vocaltec Ltd.
12 Haomanut Street, 2nd Floor
Poleg Industrial Area, Netanya, Israel 42504

VIA EMAIL TO MR. BELL

Dear magicJack Board of Directors:

The accompanying Form 13D filed with the SEC presents an opportunity to provide our views on recent developments at our company and to offer suggestions aimed at delivering value for long-suffering shareholders. At this critical juncture, we hope that you, our partially reconstituted board of directors, will provide superior governance and oversight than did your predecessors.

As indicated in our filing, client accounts managed by Twinleaf Management LLC own 809,526 shares or just over 5% of the company's outstanding equity. Having made our first ill-timed purchase of magicJack stock in summer 2013, our perspective is perhaps deeper than that of most shareholders. So is our frustration.

In light of our company's preliminary proxy statement dated June 12, 2017, certain proposals requiring shareholder vote and the ongoing strategic review process formally announced in March, we submit the following:

We are encouraged by Mr. Bell's assertiveness in remaking the company and board. With regard to his proposed compensation package, we are seeking more disclosure around the metrics in the change of control provision so that it is fully aligned with shareholder interests. The unique situation that Mr. Bell inherited upon becoming CEO in March - namely the presence of multiple unsolicited bids for the company, as disclosed in the February proxy statement - demands thoughtful structuring of compensation to absolutely reward outperformance but avoid further leakage away from shareholders.

With regard to the proposal to raise your own compensation as board members, we will vote AGAINST. A 50 per cent decline in the company's stock price over the past four years should provide sufficient evidence of vast corporate underperformance that should not be rewarded. True, there are some recent additions to our board but if any member feels that his or her board compensation is inadequate relative to stock price performance, I will gladly seek board nomination as your replacement.

With regard to the strategic review, we hope that you aim to expeditiously conclude the process. It doesn't take a genius to recognize that companies with chronic revenue declines and a history of strategic blunders are not often worth more tomorrow than they are today. If indeed there is a bona fide offer for our company at $9.50 per share, we'd like to see it signed to binding agreement and announced. Look no further than the current stock price for an indication that investors are highly skeptical.

If our board is unable to achieve that result, we urge you not to reveal such an unsatisfactory outcome to the market without a concurrent and immediate plan to return substantial cash to shareholders. Failure to neither sell the company nor return capital will further damage credibility among investors and inflict more pain on beleaguered shareholders. A high-margin, no-growth business - if combined with aggressive cost controls and prudent capital allocation - need not necessarily be the poor investment that magicJack has been.

Sincerely,

Spencer Grimes
