Press 1 IVR Telegram Bot

@Herculesz

Hi I can build a Telegram-controlled voice notification system for opt-in contact lists using Twilio, Vonage, or Plivo, with Docker deployment and a simple self-hosted setup. The main technical challenge in systems like this is handling concurrent outbound calls, DTMF capture, provider webhooks, and prompt updates without making the flow fragile, so I would solve that with an async call queue, webhook-driven IVR logic, and a small prompt-management layer. My approach would let you upload a text file of consented numbers, launch calls with a configurable concurrency limit, play prompt one, detect keypad input, optionally play prompt two, and send Telegram notifications with number and timestamp when a valid response is received. I would also make prompt updates easy through uploaded audio files or TTS text, without requiring redeployment. The delivery would include clean code, Dockerfile, env-based configuration for the voice provider, and a concise README covering setup and prompt changes. I have experience with API integrations, bots, webhook flows, and production-minded automation where reliability matters more than complexity. Thanks, Hercules

Hi , I am a software engineer , I know how to create a telegram bot to run a classic “press-1” outbound IVR campaign , contact me !

@mayankinnovative

Hi, As per my understanding: You need a Telegram-based IVR bot capable of executing high-concurrency "Press-1" outbound call campaigns to the UK, USA, and Ireland. The workflow involves uploading a text file of numbers, initiating simultaneous calls via a voice API (like Twilio or SignalWire), and capturing DTMF "1" presses. You require the ability to dynamically update audio prompts via the bot and receive real-time Telegram notifications for successful leads. Implementation approach: Bot Framework: I will build the bot using Python (python-telegram-bot) and containerize it with Docker for easy self-hosting. Voice Integration: I will use the Twilio Voice API and TwiML for call handling. TwiML will manage the <Gather> verb to detect DTMF digits and play the respective audio files. Concurrency: Using asynchronous programming (asyncio), the bot will trigger multiple API calls simultaneously without blocking. Prompt Management: I will implement a "Settings" menu in the bot where you can upload .mp3 files or input text for TTS (using Amazon Polly or Google TTS) to update prompts instantly. Lead Tracking: A webhook listener will process status callbacks from the voice provider and immediately push "Press-1" alerts to your Telegram chat. A few quick questions: Do you already have a Twilio or Vonage account with a verified "From" number? For TTS, do you have a preferred voice accent (e.g., British vs. American)?

@manojmalviya93

Hey jamesa636! I remember our work on the PhishTank URL Scanner fondly. Your new project, Press 1 IVR Telegram Bot, caught my eye - the concept of an outbound IVR campaign running through a bot sounds fascinating. If you need a hand with Python or API Integration, I'd be more than happy to chat about it. Enjoy your day!

@waqaswebmaster

Hi There This needs more than just a bot it needs a stable outbound flow with controlled concurrency, reliable DTMF detection, instant Telegram alerts, and prompt swapping without redeploy headaches. I can build this as a self hosted Docker based system with a clean Telegram workflow, voice provider integration, and a simple prompt management setup for compliant permission based campaigns. My focus would be delivery reliability, readable logs, fast notifications, and a structure that stays easy to operate on your own server after handoff. The first thing I would lock down is the call provider and webhook flow so UK, USA, and Ireland routing stays consistent under parallel load. best regards Waqas A.

@ivank69

Hi there, which voice provider do you want to use for the first version: Twilio, Plivo, or another API already approved for your traffic? Should the bot handle only consent-based outbound campaigns with clear logging and configurable concurrency limits for UK, USA, and Ireland from day one? This is a focused build, and the right approach is a Dockerized Telegram bot that accepts number lists, starts controlled parallel calls, plays prompt 1, detects DTMF 1, plays prompt 2, logs outcomes, and sends instant Telegram notifications. Prompt management can be kept simple through file upload or TTS text updates without redeploy. Worked on similar Python automation and API integration systems where concurrency, webhook events, logging, and bot-based control had to stay reliable. Also handled Dockerized tools with clean env config, provider integrations, and simple operator workflows. Those systems worked best when call flow, provider webhooks, prompt storage, and Telegram notifications were separated clearly, which made maintenance easier and reduced failures. Strong Python, Telegram API, Docker, and integration background makes this a very good fit, and ready to start immediately. Best, Ivan

Hi Client, I’m Sean, a Full-Stack AI developer with 8 years of experience specializing in Python, Telegram Bot API, and VoIP integrations (Twilio/Plivo/SIP). I’ve built outbound call automation and IVR systems that reliably handled concurrent campaigns and DTMF capture (delivered a campaign that processed 10k calls with accurate response logging). My approach is to wire a voice gateway (Twilio/Plivo or SIP) to a Docker-deployable Python service that accepts a plain-text phone list, spawns concurrent outbound calls within a configurable batch size, plays the first prompt, detects DTMF “1”, plays the confirmation prompt, logs no-response cases, and sends instant Telegram notifications when “1” is pressed; I can do this project perfectly. I typically deliver this scope in 7 days, including tests and Docker deployment scripts. I’ll include tests, logging/monitoring hooks, OWASP basics, clean code and docs, and TTS guardrails/data privacy for on-the-fly prompt generation. Please tell me the preferred voice provider and any concurrency limits to configure Which voice provider do you prefer (Twilio, Plivo, Vonage, SIP/Asterisk) and what concurrency limit would you like set as the default? Best regards, Sean
