I’ve recorded a full narrated version of my ebook and now need a simple phone-based listening experience. Here’s what I’m after: • A caller dials a dedicated number and immediately hears the pre-recorded narration. • While listening, the caller can press keys to Play/Pause, jump to the next or previous chapter, or repeat the last section. • All audio files are ready; I just need you to build the telephony application, host it (Twilio, Asterisk, FreePBX or a comparable service is fine), and provide clear instructions so I can update audio or chapters later. Deliverables 1. Working phone number with the call flow live and tested. 2. Upload of my narration files, mapped to the correct chapters. 3. Touch-tone controls: Play/Pause, Chapter navigation, Repeat last section. 4. Brief setup & maintenance guide so I can manage future updates myself. If you’ve built interactive voice applications before, especially with IVR frameworks or Twilio Studio, this should be straightforward. I’m ready to move quickly once I see your approach and timeline.

Hi, I've built several Twilio applications, including an SMS integration inside a LAMP web app with REST API and third party services, and other custom Twilio call and messaging flows. Twilio SendGrid Integration: from Adil Upwork, 5 star. SMS with Twilio and REST API: from Adil Upwork, 5 star. For your ebook, the key decision is state. Twilio calls are stateless between key presses, so I'd track chapter position and last section in a small backend that Twilio hits on each digit. That way Play/Pause, next/previous chapter, and repeat all work reliably. Your audio files map to chapters in a simple config you can edit later, which is what the maintenance guide will cover. One question: are your chapters one file each, or one long recording I need to split? We can start with a milestone so you only pay on a working tested number. Adil

Hi! Setting up an interactive dial-in audio playback flow with chapter navigation and DTMF touch-tone controls is straightforward using Twilio Voice and Twilio Studio / TwiML. Technical Architecture & Implementation: 1. Telephony Setup & Number Configuration: - Configure a local or toll-free Twilio phone number linked to an interactive voice response (IVR) call tree. - Map caller input instantly using DTMF gathering (<Gather> verb) for responsive keypress detection. 2. Touch-Tone Playback Controls: - Key 1: Previous Chapter - Key 2: Play / Pause (or Resume playback) - Key 3: Next Chapter - Key 4: Repeat Current Section / Chapter - Clean fallback: If no key is pressed, audio seamlessly flows into the next chapter track automatically. 3. Audio Hosting & Mapping: - Upload narration tracks to a high-speed, secure CDN/S3 bucket or Twilio Assets, fully indexed by chapter number for instant buffering. 4. Deliverables & Maintenance Guide: - Live, tested phone number with full end-to-end interactive dial-in playback. - Clear setup & maintenance guide showing how to swap MP3 audio files or add new chapters directly from the Twilio dashboard without writing code. - Handover of the Twilio call flow JSON and webhook configurations. Timeline: 24 to 48 hours once audio files and Twilio access are provided. Ready to begin!

Hi, I can build your dial-in ebook player using a Twilio number and a small Python backend. My profile covers voice/telecalling agents, Python and REST API integration; I would apply those skills to this recorded-audio flow without claiming a public audiobook IVR case study. I would map your files to chapters, divide long narration into short playback sections, and track each call's chapter and section so keypad controls can pause/resume, move between chapters and repeat the last section. I would test key presses during playback, invalid input and chapter boundaries, then deploy the flow and provide an audio-update guide. My quote is USD 250 for the complete flow in 7 days after receiving the audio and account access. First USD 75 checkpoint: two chapters and working keypad controls for approval; remaining USD 175: full chapter mapping, testing, deployment and handover. Twilio number, call usage and hosting are separate on your account. How many chapters and total audio hours are there? Resume would start at the current short section boundary.

EVEN IF YOU DON'T HIRE ME, YOU'LL WALK AWAY WITH A FREE CONSULTATION. You're building a phone-in ebook listening platform where callers dial a number and control playback via touch-tone commands. The two hard parts are setting up reliable IVR call routing with Twilio or Asterisk, then mapping your narration files to chapters and ensuring the Play/Pause, chapter navigation, and repeat functions work smoothly across touch-tone inputs. Here's how I'd approach it: - Map your audio files to the chapter structure and test all file transitions end-to-end - Build the IVR logic in Twilio Studio or FreePBX, wiring each keypress to the correct playback or navigation action - Deploy, test with live calls, and hand you a maintenance guide so you can swap audio or add chapters without touching the code I've designed and deployed workflow automation systems that chain multiple steps into seamless pipelines, and built payment and booking platforms requiring complex state management and user interaction, which translates directly to managing call states and keypress sequences here. Let's talk through your setup and timeline. What's your preferred platform, Twilio or self-hosted? Kind regards, Cornelius

Hi, I notice that handling caller input for Play/Pause and chapter navigation will be crucial, so I'd approach this by setting up a simple IVR system using Twilio. This will allow callers to interact with the audio playback using touch-tone controls. I'll also make sure to implement a system for uploading and mapping narration files to the correct chapters. In my experience, one common mistake is not accounting for different caller input scenarios, so I'll make sure to test the system thoroughly to handle various inputs and edge cases. As a result, the client can expect a working phone number with a live and tested call flow, upload of narration files, and touch-tone controls for playback and navigation.

Hello, I’ll build a dial-in listening service that starts your ebook narration immediately and lets callers control playback from their phone keypad. My skills cover IVR development, Asterisk, VoIP integration and audio preparation. I recommend hosted Asterisk with a dedicated number and SIP trunk, using playback controls that can pause and resume from the listening position. The proposed keypad is: 1: Play/pause 2: Next chapter 3: Previous chapter 4: Repeat the current section 0: Hear the controls I’ll map your recordings to chapters and agreed section markers, keep each caller’s playback state independent, and handle chapter boundaries and invalid key presses cleanly. You’ll receive the live, tested phone number, deployed application, organised narration files, source/configuration files and a short guide for replacing audio or adding chapters. I’ll test pause/resume, repeat, navigation, end-of-book behaviour and simultaneous calls before handover. I’m targeting 5 days after receiving the audio and hosting/provider access. My bid covers one ebook with up to 30 supplied chapter files. Phone-number rental, call charges and hosting are separate ongoing costs. Send the chapter list and audio duration, plus your preferred number country, and I’ll confirm the playback map and begin.

I see the challenge here. You want a smooth, user-friendly way for callers to enjoy your ebook audio. If the setup isn’t done right, it could frustrate users and affect their experience.

I’ll build the call flow using Twilio, ensuring they can navigate chapters and control playback with simple key presses. This way, listeners will have a seamless experience, and you’ll have the flexibility to update content later. I understand the importance of getting this right and will ensure you’re satisfied with the final product. Revisions are part of the process until everything meets your needs. What’s your timeline for this project? Do you have a preferred hosting service in mind?

Hi, I suggest an Asterisk-based call flow with DTMF controls and a chapter map, so callers can pause/resume playback, move between chapters and repeat a section. I can configure one book and number on your hosting/SIP account, convert the supplied audio as needed, test the controls and provide a simple update guide. My $250 quote covers the implementation; the phone number, hosting and call charges stay in your account and are separate. How many chapters are there, and do you already have a phone provider or VPS?

Hi, This project is a great match for my experience. I’m a Linux & VoIP engineer with 10+ years of hands-on experience in Asterisk, SIP, IVR, DTMF, audio playback, and telephony applications. During COVID-19 in 2020–2021, I worked on a similar voice-based project for a team in Australia, where callers accessed pre-recorded audio through a telephone system. So I’m very familiar with building reliable phone-based audio experiences. For your audiobook, I can build the complete solution: • Dedicated phone number with immediate narration playback • DTMF controls for Play/Pause, Previous/Next Chapter, and Repeat • Upload and mapping of all narration files • Complete deployment and end-to-end phone testing • Simple documentation for updating audio and chapters yourself I would recommend Asterisk for the core application because it provides excellent control over audio playback, DTMF events, and chapter navigation. I can also integrate Twilio or another SIP provider if preferred. My goal is to keep the caller experience extremely simple: **Dial → Listen → Control with keypad.** I can start quickly once the narration files and telephony details are available. I’d be happy to build the initial call flow first, test it, and then deploy the complete audiobook system.
