Exhibit 10.70

RELEASE AGREEMENT

This RELEASE AGREEMENT (Release) dated as of June
4th, 2009 between Comverse Technology, Inc., a New York
corporation (the Company), and Joseph R. Chinnici (the Executive).

WHEREAS, the Company
and the Executive previously entered into an employment agreement dated May 22, 2008 (as amended thereafter) under which the Executive was employed to serve as the Companys Executive Vice President and Chief Financial Officer (the
Employment Agreement); and

WHEREAS, the Executives employment with the Company is terminated
effective May 20, 2009 (the Separation Date); and

WHEREAS, pursuant to Section 13 of the Employment
Agreement, the Executive may be entitled to certain compensation and benefits upon such termination (as set forth in Exhibit 1 to this Release), contingent upon the execution of this Release;

NOW, THEREFORE, in consideration of the premises and mutual agreements contained herein and in the Employment Agreement, the Company and
the Executive agree as follows:

1. The Executive, on his own behalf and on behalf of his heirs, estate and beneficiaries,
does hereby release the Company, and in such capacities, any of its subsidiaries or affiliates, and each past or present officer, director, agent, employee, shareholder, and insurer of any such entities, from any and all claims made, to be made, or
which might have been made of whatever nature, whether known or unknown, from the beginning of time, including those that arose as a consequence of his employment with the Company, or arising out of the severance of such employment relationship, or
arising out of any act committed or omitted during or after the existence of such employment relationship, all up through and including the date on which this Release is executed, including, but not limited to, those which were, could have been or
could be the subject of an administrative or judicial proceeding filed by the Executive or on his behalf under federal, state or local law, whether by statute, regulation, in contract or tort, and including, but not limited to, every claim for front
pay, back pay, wages, bonus, fringe benefit, any form of discrimination (including but not limited to, every claim of race, color, sex, religion, national origin, disability or age discrimination), wrongful termination, emotional distress, pain and
suffering, breach of contract, compensatory or punitive damages, interest, attorneys fees, reinstatement or reemployment. This general release specifically includes, but is not limited to, any claims Executive may have under the Age
Discrimination in Employment Act of 1967 (ADEA). If any arbitrator or court rules that such waiver of rights to file, or have filed on his behalf, any administrative or judicial charges or complaints is ineffective, the Executive agrees
not to seek or accept any money damages or any other relief upon the filing of any such administrative or judicial charges or complaints. The Executive relinquishes any right to future employment with the Company and the Company shall have the right
to refuse to re-employ the Executive, in each case without liability of the Executive or the Company. The Executive acknowledges and agrees that even though claims and facts in addition to those now known or believed by him to exist may subsequently
be discovered, it is his intention to fully settle and release all claims he may have against the Company and the persons and entities described above, whether known, unknown or suspected.

2. The Company and the Executive acknowledge and agree that the release contained in Paragraph 1 does not, and shall not be construed to,
release or limit the scope of, or preclude the Executive from asserting his rights to enforce any existing obligation of the Company (i) to indemnify the Executive for his acts as an officer or director of Company in accordance with the
Companys By-laws, the



---

Indemnification Agreement (as defined in Section 15 of the Employment Agreement), and other agreements or the law, as to continued coverage and rights under director and officer liability
insurance policies, (ii) to the Executive and his eligible, participating dependents or beneficiaries under any existing group welfare, equity, or retirement plan of the Company in which the Executive and/or such dependents are participants, or
(iii) to pay any amounts payable under the terms of the Employment Agreement (including, without limitation, any severance or other items payable following termination of Executives employment) as set forth in Exhibit 1 hereto. In
addition, Executive does not waive his right to file a charge with the EEOC or participate in an investigation conducted by the EEOC; however, Executive expressly waives his right to monetary or other relief should any administrative agency,
including but not limited to the EEOC, pursue any claim on Executives behalf.

3. The Executive acknowledges that he has
been provided 45 days from his Separation Date to review the Release and has been advised to review it with an attorney of his choice. In the event the Executive elects to sign this Release prior to the expiration of this 45 day period, he agrees
that it is a knowing and voluntary waiver of his right to wait the full 45 days. The Executive further understand that he has 7 days after the signing hereof to revoke it by so notifying the Company in writing, such notice to be received by Lance
Miyamoto, Executive Vice President Global Human Resources, within the 7 day period. The Executive further acknowledges that he has carefully read this Release, knows and understands its contents and its binding legal effect. The Executive
acknowledges that by signing this Release, he does so of his own free will and act and that it is his intention that he be legally bound by its terms.

4. The Executive acknowledges and agrees that the consideration set forth in Exhibit 1 hereto represents all monies and benefits to which
he is entitled under the Employment Agreement or otherwise from the Company, other than his final pay and accrued vacation time.

5. The Executive agrees for a period of up to 30 days following the Separation Date and upon reasonable notice from the Company to
provide, without additional compensation, transition services during such regular business hours as may be reasonably requested by the Company. The Company agrees to reimburse you for reasonable expenses incurred by you in connection with the
provision of such services.

IN WITNESS WHEREOF, the parties have executed this Release on the date first above written.
