Silent Communication TWT, world patent solution, is positioned as complementary to existing call completion solutions including SMS, MMS, Voicemail and other call back mechanisms. These technologies offer new possibilities to users; however they fail to address the subscribers needs of conducting a regular voice call while remaining silent (during meetings, lectures, movies, silent situations, etc). TWT holds a unique position, as it is the only real-time human voice messaging system. שם איש קשר:
