hi, I have developed RVM many times,not on golang or freeswitch but Asterisk and PHP, I have a very good idea of what this kind of systems need, I can make things even more interesting by adding Ai to the mix and making the voicemails generated by the text to speech and Ai to make it look more personal and an approach directed towards better customer service, I can even give you a demo of some intelligent IVR system, kindly let me know if we can discuss this in detail, regards.

Dear Client, We at N&T Negocios y Tecnologias s.r.l. are proud to present our proposal for the development of the Ringless Voicemail core for high volume traffic project. As a company with 20 years of experience in the IT industry, we have proficient expertise in developing web, mobile, blockchain and AI projects. Our proposed solutions for this project include developing an RVM core that complies with modern carrier restrictions, providing an API-like interface to queue RVM drops, and push CDRs based on webhook settings set on JSON request body. To handle an audio file per request and to have multi-carrier support, we recommend using a compiled language like Go and Freeswitch dialer for scaling communications stack. We also suggest keeping a database for CDRs, configurations and eventually requests log for auditing purposes. Based on our experience in working with Ringless Voicemails on a high-performance scenario and with verified high drop ratio, we believe that the best architecture and technology to use for this project are the following: - Go programming language for high performance - Freeswitch dialer for scaling communications stack - SIP communications Please note that the budget for this project is approximate, and we believe that it will vary depending on the complexity and scope of work required. We hope that our proposal aligns with your expectations, and we would be honored to work alongside you in this project. Should you have any inquiries, please do not hesitate to contact us. Thank you for considering our proposal, and we look forward to a cordial response. Sincerely, N&T Negocios y Tecnologias s.r.l.

Hello, my name is Syeda Zainab and I am a Full Stack developer with over 5 years of experience in website and mobile app development. I understand that you are looking for someone to develop an RVM core that complies with modern carrier restrictions and provides an API-like interface to queue drops and to be able to push CDRs based on webhook settings set on a JSON request body. It should handle an audio file per request and be able to have multi-carrier support. It should keep a database for CDRs, configurations and eventually requests logs for auditing. As this is for high volume, it should be developed on a compiled language like Go and use Freeswitch dialer for scaling communications stack (programming language could be discussed). I believe I am the best fit for this project because of my extensive experience working with Ringless Voicemails on a high performance scenario as well as with verified high drop ratio. Additionally, I have experience working with SIP communications which is required for this project.
