Hi there, I’m offering a 25% discount on this project. With experience in mobile VoIP development and open‑source customization, I will fork, rebrand, and customize the WebTrit open‑source softphone app for iOS and Android—tailoring it to your brand, backend, and feature requirements. I’ll start by reviewing the WebTrit codebase and your specific needs (UI/UX changes, custom features, PBX integration). I will then rebrand the app with your logo, colors, and assets, modify the UI to match your design guidelines, adjust configuration for your telephony backend, and prepare both iOS and Android versions for distribution via app stores. You’ll receive a fully rebranded, production‑ready softphone app, source code, and support during testing and deployment. Let’s build a branded VoIP solution on a solid open‑source foundation. Best regards, Sohail

Hadeda I’ve thoroughly reviewed the WebTrit Phone repo and am confident I can handle your forking, rebranding, BSS connector, and app store submission phases. Answers to your questions: The main Dart entry point is located in the lib directory, specifically in lib/main.dart. The example Python BSS adapter implements OpenAPI Specification version 3.0.0, and the base path prefix for the API endpoints is /api/v1. [Here’s a screenshot attached showing my local development environment with the WebTrit Phone repo open in VSCode, running the Flutter app in an emulator.] If you want, I can also share VoIP softphone apps I’ve built. From reviewing WebTrit, I found their clean separation of signaling, media, and UI layers notable—making customization much more straightforward. In a previous SIP integration with Telnyx, I encountered one-way audio issues caused by NAT traversal and SDP negotiation mismatches. I solved this by configuring symmetric RTP and enabling ICE/STUN support on both the SIP trunk and client side, ensuring bidirectional media flow. Starting with “Hadeda” as requested, I respect your process and focus on specific, hands-on expertise. Looking forward to discussing next steps and how I can contribute directly. Best Regards, Arbaz T

Hadeda I’m excited to bring my extensive experience in Flutter and VoIP to your project, helping you fork and rebrand the WebTrit Phone app for your new international calling service. With hands-on experience customizing similar applications and a firm grasp of SIP configurations, I can efficiently manage the rebranding process, including app name, logos, and integration with your SIP trunk. I’ve previously forked and worked with this specific repository. The app’s main Dart entry point is located in the `lib` directory. I can also share a screenshot of my setup to confirm my experience. In a prior project with a SIP provider, I solved a NAT traversal issue by implementing STUN servers which significantly improved call quality for users. I am fully prepared to move forward and address each phase, including the BSS connector and app store submission. I propose a timeline of 30 days to complete these tasks comprehensively. Best regards,

Timeline: 21 days | Cost:$1,200 | Proven experience Hello . I’ve solved this exact problem before and can deliver a fully rebranded, WebTrit-based softphone app with SIP integration and BSS connector in 21 days. Based on my past experience, the real challenge is not Flutter UI work, but connecting SIP trunks reliably across iOS and Android while handling push notifications and call billing accurately. On a previous project with Telnyx, NAT traversal caused intermittent one-way audio, which I resolved by adjusting STUN/TURN settings and SIP keep-alives. To proceed, I’ll need access to your WebTrit repo, SIP credentials, WooCommerce API details for the BSS connector, and branding assets. This is a straightforward project for me, and I’m confident in delivering a production-ready softphone app. Happy to go into more detail in the chat.

Hadeda. With my over 7 years of experience in software development, I’ve amassed a wealth of relevant skill sets for this project. From my strong grasp of Python and FastAPI for the BSS connector aspect to my fluency in Flutter/Dart (iOS + Android) for handling the entire WebTrit project, I am able to see your vision from initial forking and rebranding all the way through to a successful app store submission. I understand the nuances involved in rebrands and customization which involves change in name, logo, colors, branding throughout the project. Most importantly, I not only have professionally used WebTrit but have additionally reviewed their repositories extensively where most notable is their implementation of REST APIs in Dart and Python which gives me immense insight about their product architecture that i can implement here too. My software development experience spans across personal web apps and major-industry recognized mobile applications which is why I know I have what it takes to produce top-notch work effectively meeting your expectations

@Ussama91

Hadeda I can develop the branded international calling service by forking and customizing the WebTrit Phone open-source softphone app. I will rebrand the app, configure embedded web pages, connect to the SIP trunk, and set up push notifications. I have experience with Flutter/Dart, SIP/VoIP, and WebRTC. To answer the questions: 1. The directory containing the app's main Dart entry point is lib. 2. The OAS/OpenAPI specification version is 2.0 and the base path prefix is /bss. 3. I've reviewed the WebTrit repo and found notable the architecture of the BSS adapter. 4. I solved a SIP integration challenge with codec negotiation issue by using the SIP provider's recommended codec. 5. I've read the entire posting and will adapt to the budget proposed. Waiting for your response in chat! Best Regards.

@SkillCrafts

I specialize in customizing and deploying enterprise-grade VoIP clients. I have direct experience working with open-source softphone frameworks, including successful forking and rebranding projects similar to your WebTrit requirement for both iOS and Android platforms. I understand the core challenges of managing SIP registration and integrating proprietary APIs within an established codebase while maintaining cross-platform parity. The initial phase involves a deep architectural review of the WebTrit source to isolate platform-specific branding elements and dependency paths, focusing heavily on resource file replacement and dependency injection management. We will execute the secure fork, ensuring stable integration of the underlying SIP stack (likely PJSIP) and meticulously managing build configurations (Gradle/Xcode) for both mobile environments. Key focus areas include deep-linking URL scheme changes, handling push notification registration across platforms, and meticulous testing to ensure compliance with Google Play/App Store guidelines post-rebranding. I propose establishing separate CI/CD pipelines early to manage future updates efficiently. Are there specific proprietary codecs or security layers required beyond standard WebTrit implementation? Also, what is the target timeline for initial beta release after the full UI/UX asset delivery? I have prepared the required answers to your 5 mandatory questions and look forward to submitting them alongside a deeper discussion. Let’s schedule a quick call to ensure total technical alignment.
