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. The development platform or operating system is not a concern, as the project can be completed using either the Linux/Windows WhatsApp executables or the Android/Windows Phone mobile versions of the application, regardless of the version number. The gateway must return appropriate call error codes to the SIP backend, such as CALL SUCCESS, BUSY, UNAVAILABLE, etc. To determine the success of the project, we will choose the solution that consistently triggers successful SIP/WhatsApp calls. Step-by-Step Process: Incoming calls will be directed to the WhatsApp gateway. The gateway will then convert the SIP/IAX signal to the WhatsApp protocol. The termination number, taken from the origination header, will be verified by the WhatsApp gateway. If the number is in use by WhatsApp and the recipient is online, the call will be completed on WhatsApp. If the number is not in use by WhatsApp, the gateway will send a 503 error and the call will be redirected to other gateways.
