Asterisk call termination to whatsapp

I am looking for a freelancer who can help me with my project of Asterisk call termination to WhatsApp. I have a cloud-based system for call termination and I require the specific call feature of call forwarding. I expect to handle more than 10 concurrent calls. The scenario is as follows: - The Asterisk PBX is hosted on AWS on Ubuntu 22.04 LTS - The asterisk PBX is able to make and receive calls already with the regular dial plan. Based on existing endpoints in conjunction with a Twilio elastic sip trunk. - As a second option we want Asterisk to dial a whatsapp endpoint. - We don't want any 3th party subscription options. - Any information on what Whatsapp Gateway service we can use appreciated. We prefer Twilio. But are not sure if Twilio is offering a Sip to Whatsapp Gateway service - You will build the script / library that enables asterisk to terminate calls to a whatsapp endpoint. - Asterisk is build from source. - A AWS Vps to work on can be provided Here is what the dial plan code could look like that needs the extra option for whatsapp calls same => n,Dial(PJSIP/+${outboundNumber}@${trunkprovider}&PJSIP/${whatsappNumber}@${whatsappTrunkPriver},30) Deliverables - Documentation on how to build asterisk from source with extra libraries etc - A proof of concept that it works. Ideal skills and experience for this job include: - Strong knowledge and experience with Asterisk call termination - Experience with integrating Asterisk with WhatsApp - Familiarity with cloud-based systems - Proficiency in configuring call forwarding features - Ability to handle a high volume of concurrent calls If you have the necessary skills and experience, please bid on this project. If you read all this, before you start tell us what version of linux is being used for asterisk.
