Until November 2015, the application was called TextSecure and allowed only instant messaging. Together with the new name, the call function of the RedPhone application was turned on. In March 2017, Signal switched to a new call system based on WebRTC , which made it possible to make video calls [8] [9] .
The signal is being developed by Open Whisper Systems . Client applications are distributed under the GPLv3 license . Server code is available under the AGPLv3 license. In February 2018, the Signal Foundation, a non-profit foundation, was launched with initial funding of $ 50 million.
