It is necessary to develop a frontend SIP client (browser-based SoftPhone) using SIP.js.

Previously, we planned to create it for macOS, but we want something more universal for all devices, so we found that there is an option to create a calling application through the browser and the SIP.js client.

The application must work with a SIP server, handle calls, accept, decline, and park calls. Additionally, integration with the existing CRM (custom, API available) is required.

Familiarize yourself with the technical specifications here. There are no specific design requirements; we can use some bootstrap or tailwindcss, generated through AI.

The mockups show the design for macOS, but we need to implement it specifically in the browser, i.e., a browser tab opens, and the login process starts, loading all SIP credentials from the API, registration, and the ability to receive and make calls to numbers.

We need very responsible developers who do not disappear and are available, let's say, always: after launch, for a week or two, they need to be in touch to fix errors and problems, and if there is a critical issue, they will need to check even at night.

You are looking for a unique solution for a universal SIP client application, and you are on the right track by choosing a browser-based platform. My experience in developing web applications on React is exactly what is needed to solve the task of integrating SIP.js with your CRM. I offer a comprehensive approach to the project: coordinated work through all stages of development and testing to ensure the perfect operation of your SoftPhone with minimal delays and maximum reliability. I will always be available for support after launch, even in case of critical issues. I am ready to discuss the details.

Hello. The thing is that with such a technical specification, not all features can be implemented in the browser and/or not in the desired form. The browser is essentially an isolated and limited environment, and many things are not guaranteed or are unstable in terms of execution time, not to mention the inconsistency in functionality between different browsers. I have already placed a bid on your previous project, where you wanted to create a desktop application for macOS, and I suggested the possibility of creating a cross-platform desktop application in C#, where your new requirement of being "more universal and for all devices" would be met.
