Except as specifically provided herein, this Amendment No. 7 does not modify any of the information previously reported on the Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is supplemented as follows:

On October 18, 2015, New Acquisitions Corporation (the “Purchaser”), Enghouse Systems Limited (“Parent”) and CTI Group (Holdings) Inc. (the “Issuer”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, Purchaser has agreed to commence a cash tender offer (the “Offer”) to purchase all outstanding shares (“Shares”) of the Issuer’s Class A common stock, par value $0.01 per share (“Common Stock”), at a price of $0.61 per Share, net to the seller in cash without interest and less any required withholding taxes (the “Offer Price”). Subject to the terms and conditions of the Merger Agreement, following the consummation of the Offer (and, if required by applicable law, subject to the approval of Issuer’s stockholders): (i) Purchaser will be merged with and into the Issuer, and Issuer will continue as the surviving corporation and a wholly owned direct or indirect subsidiary of Parent (the “Merger”); and (ii) each Share outstanding immediately prior to the effective time of the Merger (the “Effective Time”), other than Shares then owned by Parent, Purchaser and the Issuer, will be converted into the right to receive an amount per Share, in cash, equal to the Offer Price. The purpose of the Offer and the Merger is to enable Parent to acquire control of the Issuer by acquiring all of the outstanding Shares.

Tender and Support Agreement

In connection with the Merger Agreement, on October 18, 2015, Mr. Osseiran, Parent and Purchaser entered into a tender and support agreement (the “Tender and Support Agreement”), pursuant to which Mr. Osseiran has agreed, among other things, to validly tender the Shares beneficially owned by Mr. Osseiran in the Offer, including any additional Shares that he may acquire after the date of the Tender and Support Agreement (collectively, the “Support Shares”).

Mr. Osseiran has agreed that, unless the Tender and Support Agreement is terminated as described below, (i) he will validly tender or cause to be validly tendered the Support Shares to Purchaser pursuant to the Offer as promptly as practicable, and in any event no later than the tenth business day following the commencement of the Offer (or in the case of any Support Shares directly or indirectly acquired subsequent to such tenth business day, no later than two business days after such acquisition), and (ii) he will not withdraw any of the Support Shares tendered in the Offer.

Mr. Osseiran has also agreed that, unless the Tender and Support Agreement is terminated as described below, Mr. Osseiran will not, prior to such termination: (i) transfer, assign, sell, gift-over, pledge or otherwise dispose of, or consent to any of the foregoing, any or all of the Support Shares or any right or interest therein; (ii) enter into any contract, option or other agreement, arrangement or understanding with respect to any such transfer; (iii) grant any proxy, power-of-attorney or other authorization or consent with respect to any of the Support Shares; (iv) deposit any of the Support Shares into a voting trust, or enter into a voting agreement or arrangement with respect to any of the Support Shares; or (v) take any other action, other than in Mr. Osseiran’s capacity as a director of the Issuer, that would in any way restrict, limit or interfere with the performance of Mr. Osseiran’s obligations under the Tender and Support Agreement or the transactions contemplated thereby. Notwithstanding the foregoing, Mr. Osseiran may make (i) transfers of Support Shares by will or by operation of law or other transfers to immediate family members, trusts for the benefit of Mr. Osseiran, any immediate family member of Mr. Osseiran, charity or other transfers for estate

CUSIP No. 126431 10 5 Page 6 of 10

planning purposes, or upon the death of Mr. Osseiran, in which case any such transferee shall agree in writing to be bound by the Tender and Support Agreement prior to the consummation of any such transfer; (ii) with respect to any options or warrants to purchase Shares, transfers of Support Shares to the Issuer (A) in payment of the exercise price applicable to each such options or warrants or (B) in order to satisfy required withholding taxes applicable upon the exercise of such options or warrants, (iii) with respect to any restricted stock units issued by the Issuer, transfers of Support Shares to the issuer in order to satisfy required withholding taxes applicable upon the vesting of such restricted stock units, and (iv) other transfers of Support Shares as Parent may otherwise agree in writing in its sole discretion.

Unless the Tender and Support Agreement is terminated, Mr. Osseiran irrevocably granted to, and appointed, Parent and any designee of Parent, Mr. Osseiran’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of Mr. Osseiran, to vote the Support Shares, or to grant a consent or approval in respect of the Support Shares, in connection with any meeting of the stockholders of the Issuer or any action by written consent in lieu of a meeting of stockholders of the Issuer (i) in favor of the Merger or any other transaction pursuant to which Parent or Purchaser proposes to acquire the Issuer, whether by tender offer, merger, or otherwise, in which stockholders of the Issuer would receive consideration per Share equal to or greater than the consideration to be received by such stockholders in the Offer and the Merger, and/or (ii) against any action or agreement which would impede, interfere with or prevent the Merger, including, but not limited to, any other extraordinary corporate transaction, including a merger, acquisition, sale, consolidation, reorganization or liquidation involving the Issuer and a third party, or any other proposal of a third party to acquire the Issuer. Further, unless the Tender and Support Agreement is terminated, Mr. Osseiran agreed to vote the Support Shares as instructed by Parent in writing, if for any reason the proxy granted in the Tender and Support Agreement is not irrevocable.

Mr. Osseiran also agreed that he will not, and will cause his affiliates and representatives to not, directly or indirectly, (i) solicit, initiate or intentionally encourage (including by way of providing information) the submission or announcement of any inquiries, proposals or offers that constitute a Takeover Proposal (as defined in the Merger Agreement); (ii) participate or engage in any discussions or negotiations with any person or entity with respect to a Takeover Proposal; (iii) otherwise cooperate with or assist or participate in, or knowingly facilitate any such inquiries, proposals, offers, discussions or negotiations; or (iv) enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar contract relating to a Takeover Proposal or enter into any contract or agreement in principle requiring Mr. Osseiran to abandon, terminate or fail to consummate the transactions contemplated by the Tender and Support Agreement; provided, however, that Mr. Osseiran is not precluded from acting in his capacity as a director of the Issuer, or taking any action in such capacity (including at the direction of the Issuer’s board of directors), but only in either such case as and to the extent permitted by the Merger Agreement. Mr. Osseiran agreed to, and to cause his affiliates and representatives to, immediately cease participating in any solicitation, discussion or negotiation with any person or entity (other than Parent and Purchaser) with respect to any actual or potential merger, acquisition, sale, consolidation, reorganization or liquidation involving the Issuer and a third party, or any other proposal of a third party to acquire the Issuer. Mr. Osseiran also agreed to, as promptly as practicable, notify Parent in the event that Mr. Osseiran or any of his respective affiliates or representatives receives any Takeover Proposal within twenty-four hours after such receipt.

The Tender and Support Agreement terminates upon the earliest to occur of (i) termination of the Merger Agreement in accordance with its terms; (ii) the Effective Time; (iii) an Adverse Recommendation Change (as defined in the Merger Agreement) in accordance with the Merger Agreement; (iv) the date of any amendment to the Merger Agreement that changes any terms of the Offer or the Merger without the prior written consent of Mr. Osseiran that (A) reduces the Offer Price or the Merger consideration, or (B) changes the form of consideration payable in the Offer or the Merger; (v) the termination of the Offer or the Expiration Date (as defined in the Merger Agreement) shall have occurred, in each case, without acceptance for payment of the Support Shares pursuant to the Offer; and (vi) the mutual written consent of Parent and Mr. Osseiran.

Mr. Osseiran was not paid any additional consideration other than the consideration contemplated in the Merger Agreement in connection with the execution and delivery of the Tender and Support Agreement. The purpose of the Tender and Support Agreement is to increase the likelihood that the Offer and the Merger will be consummated.
