>Background We are designing a software that will enable users to make video calls from the browser. Callers and receivers of calls will use a web-based (WebRTC) SIP client (using JsSIP). We would like to use Asterisk 13.8 running on an Ubuntu 14.04 LTS server as SIP server and PBX. We will provide a fresh Ubuntu 14.04 LTS server. >Task Main task is to set up Asterisk on this server in order to place video calls (supporting both VP8 and H264 video codecs and Opus as audio codec) from one web-based SIP client to another. We shall also allow for sending instant messages with SIP Message. Further, we ask for detailed instructions on how to setup Asterisk. This shall be done by either allowing us to observe the setup of Asterisk or by providing a very detailed instruction. >Your credentials and offer Please provide your credentials solving similar issues.
