Ack Phone is a brand new name that has just joined the VoIP calling industry. However, this does not mean that Ack Phone is a fledgling application. We often tell each other, “If we start later than others, we need to run faster than them,” the quality of Ack Phone is no less than that of the big names already in the market, regardless of their seniority.

Currently, pre-registered customers of Ack Phone, including us, the 20PlayTesters, can download the application from Google Play via the link https://play.google.com/store/apps/details?id=com.voicecloud.ackphone&hl=en. For customers who are interested in this service, please contact the application author directly through the App description section to receive special offers.

20PlayTesters believea that Ack Phone will become much more popular in the VoIP industry, and we are very honored and proud to have contributed 20 bricks to create a solid foundation for them. We sincerely thank Ack Phone for trusting and choosing to partner with us. We hope to have the opportunity to cooperate in the future.
