Button will connect to our Asterisk PBX. 2) Install and configure OPUS on Asterisk to accept this webrtc codec (in passthrough mode since asterisk doesn't transcode OPUS) 3) Recommend, install, configure and test a windows softphone with Opus for our call center so that we can verify that the entire solution is working.
