Exhibit 99.1

Elephant Talk Communications Corp. Receives Extension until November 17, 2014 for NYSE MKT Compliance Review

OKLAHOMA CITY, OK — May 15, 2014 - Elephant Talk Communications Corp. (NYSE MKT: ETAK) (“Elephant Talk” or the “Company”), a global provider of Software Defined Network Architecture (ET Software DNA® 2.0) platforms and cyber security solutions, today announced that the NYSE MKT LLC (the "Exchange") has notified the Company that it has extended the review period for which the Company can work to regain compliance with the Exchange's listing standards until November 17, 2014.

Based on the Exchange’s review of updated information provided by Elephant Talk during the prior plan period, the Exchange has determined that, in accordance with Section 1009 of the Exchange's Company Guide (the “Company Guide”), Elephant Talk has made a reasonable demonstration of its ability to regain compliance with Section 1003(a)(iv) by the end of the revised plan period, or November 17, 2014. The Company will continue to remain subject to periodic review by the Exchange during the extended plan period. Failure to make progress consistent with the plan or to regain compliance with the continued listing standards of the Exchange by the end of the extended plan period may result in the Company being delisted from the Exchange. The Exchange has indicated that the November 17, 2014 extension is the maximum allowable extension under Section 1009 of the Company Guide.

Mr. Steven van der Velden, Chairman and CEO of Elephant Talk, stated, "Management has been working with the Exchange and we are confident in our ability to regain compliance with the Exchange’s listing standards. With the appointment of independent directors Geoffrey Leland and Carl Stevens to our board in March, we were able to cure the corporate governance deficiencies identified by the Exchange and regain compliance with Sections 802(b) and 803(B)(6)(b) of the Exchange’s Company Guide. As we continue to work to finalize the payment mechanism under our Vodafone contract, we believe that revenue from our Vodafone contract will, in time, help us regain compliance with the Exchange’s continued listing standards.”
