Greetings Kishore, Thank you for considering me for your VOIP softphone app project. Your requirements are clear, and I understand the importance of creating a robust and versatile application that operates seamlessly across both iOS and Android platforms. To ensure I fully grasp the scope and specifics of your project, I have a few questions: 1. Could you specify the APIs that the app needs to integrate with? This will help in understanding the complexity and the work involved in integration. 2. Is there a particular reason for the emphasis on certificate pinning, and are there any specific security protocols you're aiming to adhere to? 3. Regarding the OPENSIPS knowledge, are you looking for experience in setting up and managing an OPENSIPS server, or just the integration part on the app side? While I cannot provide direct links to previous work due to confidentiality agreements, I can share that my portfolio includes a secure messaging app with end-to-end encryption, a video conferencing tool that supports multiple participants, and a unified communications app that integrates voice, video, and text messaging on a single platform. These projects have given me a solid foundation in the key features you're looking for, such as video and conference calling, as well as SMS/MMS messaging capabilities. I look forward to your response to my queries and am eager to discuss how my background aligns with your project needs. Best regards,
