I need a seasoned Android engineer to fork the open-source Linphone project, apply my brand, and extend its audio capabilities. The visual refresh will cover the usual touch-points—logo, colours, name, icon and splash—so the finished APK feels fully ours rather than a generic Linphone build. The bigger change lies under the hood: during an active SIP call the user must be able to stream audio from different sources, with the microphone taking precedence. A bespoke in-call panel should let the user tap once to keep the mic live, or switch to an audio file or even the device’s system sound in future iterations. Please design this selector from scratch so it blends with the new look instead of relying on Linphone’s stock UI elements. Key deliverables • Branded Linphone Android source + signed release APK • Custom audio-input selector UI wired to Linphone’s core (mic working, hooks ready for file/system sound) • Clear build & deployment instructions for Android Studio Acceptance I will install the APK, place a SIP call, toggle to each available input and verify that the far side receives the chosen stream without glitches. Once that passes and the visual assets match the brand guide, the milestone is complete.

✔️✔️✔️✔️ I can fork and customize the Linphone Android project, apply your complete branding, and extend the in-call audio architecture. I’ll build the custom audio-input selector UI and integrate it with Linphone’s audio pipeline so the microphone remains the default/priority source, while keeping clean hooks for future audio-file and system-audio inputs. I’ll also handle Android compatibility, call-state transitions, audio focus/routing, and avoid glitches or interruptions during active SIP calls. Deliverables will include the branded Android source, signed release APK, custom in-call UI, and clear Android Studio build/deployment documentation. I’ll test the actual SIP call flow and verify that the selected audio source is correctly received by the remote party. best regards

Hi, I can fork and customize the open-source Linphone Android project, apply your complete branding, and extend the in-call audio architecture. I have 9+ years of mobile development experience, including native Android/Kotlin, audio/media handling, SIP/API integrations, custom UI and production app releases. Approach: * Fork and configure the Linphone Android source * Replace app name, logo, colours, icon and splash screen * Build a custom in-call audio selector matching your branding * Keep microphone as the primary/default input * Integrate microphone switching cleanly with Linphone Core during an active SIP call * Structure the audio-input layer so audio file and system audio sources can be added later * Handle call lifecycle, audio focus and switching without disrupting the SIP session * Test incoming/outgoing audio on real Android devices * Provide signed release APK + complete Android Studio build/deployment instructions I’ll keep the changes modular so future audio sources can be added without rewriting the call layer. I’m comfortable working directly with an existing open-source codebase and debugging issues at both the Android and native/core integration levels. Ready to review the Linphone version/source and brand assets and start.

Hi, I have experience with Android applications involving real-time audio, SIP/WebRTC-style communication, custom UI and native Android media handling. ? The main challenge is integrating multiple audio sources into Linphone’s existing media pipeline without disrupting SIP call stability, while keeping microphone priority and leaving clean hooks for future sources. ✅ Linphone & branding: I can fork and customize the Android project with your logo, colors, app name, icon, splash screen and a consistent custom in-call interface. ✅ Audio routing: I’ll connect the custom selector to Linphone’s core so the microphone remains the default input, with an architecture ready for file and system-audio sources. ✅ Testing & delivery: I’ll test switching during active SIP calls, verify the far-end audio stream, prepare the signed release APK and provide Android Studio build/deployment instructions. I can work directly on the existing Linphone architecture rather than rebuilding the communication layer, keeping the implementation maintainable for future audio features. Best regards, Michel.

Hello, I have read your project requirement description carfully! I can fork and rebrand the Linphone Android project while keeping the SIP/audio path stable. The important part is integrating the custom input selector at the correct media layer so microphone audio keeps priority and switching sources does not introduce call glitches. I’ll update the app identity, logo, colours, splash and UI, then trace Linphone’s audio routing into a clean selector component with microphone support and extension points for file/system audio. I’ll validate SIP calls on-device, package the signed APK, and provide reproducible Android Studio build/deployment instructions. Which Linphone Android version/branch and branding assets should I start from? Looking forward to working with you. Muheebwa

Hello, I’m an experienced Android developer and can customize the open-source Linphone project into a fully branded SIP application while implementing the required audio-input functionality. I’ll handle the complete rebranding, including the app name, logo, icon, colours, splash screen, and a custom in-call interface designed to match your brand rather than Linphone’s default UI. For the core functionality, I’ll integrate a custom audio-source selector directly with Linphone’s SIP/media layer. The microphone will remain the primary input, while the architecture will include clean hooks for future audio-file and Android system-audio sources. I’ll ensure switching inputs during an active SIP call is reliable and that the selected stream is actually received correctly by the remote party. Deliverables: • Branded Linphone Android source code • Signed release APK • Custom audio-input selector UI • Working microphone routing • Extensible audio-source architecture • Android Studio build/deployment documentation I’ll maintain clean, well-structured code and clearly document any Linphone core modifications for future maintenance. I’m ready to start and would be happy to review the Linphone version and brand assets before implementation.

HI, Dear. I understand this is more than a Linphone rebrand. The important part is integrating a custom audio source selector into the SIP call pipeline while keeping microphone priority and call stability intact. My experience includes Android, React Native, APIs, real time systems, audio/video processing and mobile debugging. I can fork and rebrand Linphone, implement the custom in call selector, connect microphone routing to Linphone’s audio pipeline, and prepare clean hooks for future file and system audio sources. I’ll also provide the signed APK, complete source and clear Android Studio build instructions, with testing focused on reliable audio switching during active SIP calls. Thanks, Miguel.

Hello, I’m Fernando from Mexico. I reviewed the requirements and understand the main work is rebranding the Linphone Android app and adding a custom in call audio selector while keeping the microphone working as the priority. My background includes Android, Java, mobile development, UI work and application integration. I have not worked with this exact Linphone audio pipeline before, so I would first verify its current media and audio input architecture rather than overpromise the integration. Should the audio selector initially expose only microphone and a prepared hook for future sources, or should file playback also work in the first milestone? This changes the media pipeline scope. For system audio, should the future source capture Android playback audio through AudioPlaybackCapture, or come from a dedicated internal stream? This affects Android compatibility and permissions. I can start by forking the project, applying the branding and tracing the current audio input path as the first reviewable step. Bests, Fernando

I’ll connect the selector to Linphone’s media path, test SIP calls for stable far-end audio, and verify the branded UI across the target device. You’ll receive the Android Studio source, signed release APK, and clear build/deployment instructions. I’ll keep changes focused and maintainable so future audio sources can be added without reworking the call system. Thanks
