    Bid only if you have previous experience with chan_mobile on asterisk, if not please don’t bid! I have a problem on my pbx system using chan_mobile, the outgoing voice quality is clear but the incoming voice quality is so bad.

Please bid only if you already tried chan_mobile and know how to solve the incoming voice issue problem. P.S. I tried on both asterisk 16 and 20 and the issue is the same.

    WhatsApp Gateway 6 дней(-я) left

    The goal of the project is to create a SIP to WhatsApp gateway that will allow voice calls to be passed from SIP to WhatsApp, ensuring that the call reaches its intended recipient.

Step-by-Step Process: Incoming calls will be directed to the WhatsApp gateway. The gateway will then convert the SIP/IAX si...

    Asterisk + Kaldi Realtime Speech Recognition 1 день left

    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.
