    Please bid only if you can do it and only write your exact bid for the project. I want a simple light java gui or a web app that will show the status of the asterisk channels. It’s gonna be like a table showing in the first column the channel name and second column the status (up-down-free-dialing-ringing-talking…) Also next to each channel we want a button that will block or unblock a channel. The person doing this must have great knowledge in Asterisk AMI. The gui or the web app can show channels from multiple asterisk servers and add them in 1 table for simple monitoring.

    We have a android app with in app video calling functionality using twilio library. The video call is initiated from the admin panel which in turn sends out a voip notification to the mobile device. Generally, the functionality works when the phone's screen is on, but when it's in ideal stage, the screen is off and when I'm trying to call, the screen doesn't wake up during that time. We are only accepting bids from experienced developers who have worked on similar projects in the past. More details over the chat. Please include the word in the title of your bid.  "VOIP CALL". Otherwise I will report your bid.

    Hi everyone, I'm looking for experienced VoIP Engineer to give us helping hand on real-time speech recognition system we are building. Our stack: Debian, Asterisk v.16-19, Kaldi + Vosk, Python/Javascript (node.js) The main problem is that we are unable to pick a real-time stream of RTP which is a plain UDP, transform it to Websocket data and send to the Kaldi server to recognize. We would prefer to get it done without Kamailio and RTPengine for now, just plain Asterisk possibilities like UnicastRTP, ARI etc. So we are seeking for experienced Asterisk engineer who can give us a valuable hint, share experience and/or write some code for us. Thank you in advance.
