Telegram IVR Lead-Calling Bot

@kamran2012

This looks like a great fit, I will debug your existing bot, wire the Telegram side to a voice gateway — Twilio or FreeSWITCH — and deliver the full dial-play-DTMF-summary flow. Concurrency will be configurable via an env variable so you can throttle without touching code. One thing I will add: a per-number retry with exponential backoff for unanswered calls, so carrier rate limits do not silently drop leads from your summary. Questions: 1) Do you already have a Twilio or SIP trunk account, or should I set one up? 2) What is the typical batch size — dozens or thousands of numbers per file? Ready to start whenever you are.

@billybryan98

Hello there, I’ve read your Telegram IVR Lead-Calling Bot brief and I’m confident I can fix the voice path so calls actually go out, while keeping everything secure and scalable. I’ve built and maintained PBX/VoIP integrations across PHP, Python, and Linux environments, wired to Telegram bots, and I’ve implemented configurable concurrency and US-only dialing in production systems. I’ll implement a clean gateway integration (Twilio, Asterisk, or FreeSWITCH - whichever you prefer) with a clear env-based configuration, ensure only USA numbers are dialed, and expose a tunable concurrency setting to respect carrier limits. The workflow will load numbers from a TXT file, play your first MP3 on answer, detect DTMF 1, play the second MP3, and then end the call. A Telegram summary will list successfully called numbers once processing completes. I can deliver a fully working bot, a simple README for setup/deploy on Linux, and a concise test report proving call and DTMF flow, all within your target turnaround. Best regards, Billy Bryan

@ShaunG24

Hi, The main technical challenge here is ensuring that the Telegram bot can effectively make calls while handling simultaneous connections. This is crucial because a failure in this area could lead to missed opportunities and inefficient lead processing. Using a reliable voice gateway like Twilio or Asterisk will be essential to manage call concurrency and ensure smooth DTMF capture. I can mitigate potential issues by implementing thorough logging and error handling to monitor call status and troubleshoot any failures in real-time. Your requirement for a bot that uploads a .txt file of U.S. mobile numbers and plays specific MP3 prompts aligns well with my experience in building automated communication systems. I have previously developed similar IVR solutions that required reliable call handling and efficient data processing, ensuring user interactions were seamless and effective. My approach will include: - Setting up the voice gateway and configuring the Telegram bot to handle calls. - Implementing the file upload and audio playback functionalities. - Conducting rigorous testing to confirm successful call connections and DTMF responses. - Providing detailed documentation for setup and deployment. I would love to clarify a few points to ensure we are aligned: - What specific voice gateway do you prefer, or are you open to suggestions? - Could you provide more details on the expected call throughput for concurrency configuration? Regards, Shaun

@carlosd178

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience handling Telegram bot automation, VoIP call flows, and Linux-based deployment, and I’m available to start your project right now. I bring deep expertise in Python, Linux, Telegram API, VoIP, SIP, Asterisk PBX, and Bot Development. One of the key challenges in projects like this is reliably connecting the Telegram workflow to the voice gateway, so I would focus on fixing the current call-initiation issue, wiring the IVR flow correctly for answer detection, DTMF 1 capture, second-audio playback, configurable concurrency, and clean USA-only number validation with env-based configuration for simple VPS deployment. I have a couple of quick questions. • Which voice stack is your current bot using now, such as Twilio, Asterisk, or another provider? • Do you already have server logs or error details for the current “bot not making calls” issue? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos

@cindyviorinar

Hi, I am Cindy Viorina, a developer experienced in Python, Asterisk/SIP integrations and Telegram bots. I understand your Telegram bot currently handles chat input but fails to place calls; you need a system that dials U.S. mobile numbers from a dropped .txt, plays an initial MP3, waits for DTMF "1", plays a closing MP3, and returns a Telegram summary. I will diagnose and fix the call path, wire a voice gateway (Twilio or Asterisk/Freeswitch as preferred) to the Telegram Bot API, enforce USA-only E.164 validation, implement configurable concurrency, and log per-number results. Technically I will reproduce the failure, add a SIP/REST call module to initiate calls, stream MP3s via the gateway, capture DTMF events, and ensure credentials live in an env file. Concurrency will be tunable and rate-limited to avoid carrier blocks. I am available to communicate in real-time in your time zone and can provide a simple demo or a portion of the project within 12 hours of starting. Q1: Which voice gateway do you prefer or is there existing account/credentials for Twilio or an Asterisk server? Q2: Do the MP3 files require on-the-fly transcoding or are they already in gateway-friendly format (PCM/16k/mono)? Q3: What maximum simultaneous calls per minute should we target for initial configuration? Do you have an existing voice gateway account (Twilio, Plivo) or a reachable Asterisk/FreeSWITCH server I can test with? Best regards, Cindy Viorina
