Click-to-call, Click-to-hang-up using Asterisk Manager api (AMI) In click-to-call (in outbound) api first call hit the agents number (not using softphone or hardphone) after receiving call in agents mobile then customer number will dial. Also handling the Inbound PBX – Call is hitting in a virtual number after that call will forward in agent mobile number. WebRTC – HTTP/WebSocketSecure (WSS), PJSIP with DTLS encryption. Sngrep – to monitor the sip calls. Webhooks – Send real time call data Using Dial plan, AGI, or AMI. Web Sockets – Web RTC based browser phone. STIR/SHAKEN – Identify the source of a call. Current Project – IVR Integration with Chat bot System using asterisk 13 and above version with FreePBX. With Speech to text and text to Speech (Speech Recognition). Chabot is also integrated with vicidial (in cloud) for inbound and outbound calls after that call will transfer to live agents.

Hello there, I will set up your Asterisk AMI click-to-call and click-to-hang-up flow, inbound PBX routing to agent mobiles, WebRTC via PJSIP with DTLS, and webhook-based real-time call data delivery. For your IVR chatbot integration, I will wire AGI scripts to handle STT/TTS handoff — keeping latency low by streaming audio chunks rather than waiting for full utterances before processing. Questions: 1) Which STT/TTS providers are you using — Google, AWS, or something else? 2) Is the Vicidial instance already configured, or does it need setup as well? Ready to start whenever you are.

Hi there, I will integrate click-to-call / click-to-hang-up flows using Asterisk AMI and FreePBX (Asterisk 13+) so outbound calls ring agent mobiles first, then bridge to the customer; I’ve deployed secure WebRTC (WSS + PJSIP+DTLS), sngrep monitoring and STIR/SHAKEN verification in similar PBX environments. - Implement AMI-driven outbound click-to-call and click-to-hang-up that dials agent mobile first, then customer; include AGI hooks for chatbot handoff to live agents (vicidial integration). - Configure inbound virtual-number routing to agent mobiles, IVR + speech-to-text / TTS integration and DB logging to MySQL; provide Webhook events via AMI/Dialplan. - Deploy WebRTC browser-phone (WSS) with PJSIP+DTLS, sngrep SIP monitoring, and STIR/SHAKEN attestation on outbound trunks. - QA & rollout: staged deployment, post-fix validation, rollback plan and minimal-downtime cutover; provide deployment notes and testing checklist. Skills: ✅ Asterisk PBX ✅ WebRTC (WSS), PJSIP ✅ AMI / AGI workflow and Webhooks ✅ Linux server deployment / FreePBX / SIP trunking ✅ VoIP security, STIR/SHAKEN, sngrep monitoring Certificates: ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ cPanel® & WHM Certified CWSA-2 I’m available to start immediately, deliver within 5 days for the initial integration. What SIP trunk/provider will you use for STIR/SHAKEN and outbound caller ID verification, and do you have existing TLS/DTLS certificates or should I provision them? Best regards,

Your IVR-chatbot integration will fail under load if you're using AGI scripts synchronously - I've seen this crash systems at 50 concurrent calls when speech recognition latency spikes above 2 seconds. Before architecting the solution, I need clarity on two things: What's your current call volume during peak hours, and are you handling STIR/SHAKEN attestation at the carrier level or implementing it in Asterisk dialplan? This determines whether we need FastAGI with connection pooling or async AMI event handlers. Here's the architectural approach: - ASTERISK AMI: Build event-driven click-to-dial using originate commands with channel variables to track agent state, preventing double-dials when agents are already on calls. - WEBRTC + PJSIP: Configure DTLS-SRTP with proper certificate chains and implement ICE candidate handling to prevent one-way audio issues that plague 40% of browser-based softphones. - MYSQL OPTIMIZATION: Index CDR tables on calldate and disposition columns, implement partitioning for tables over 10M records to keep webhook queries under 100ms. - SPEECH RECOGNITION INTEGRATION: Use FastAGI instead of standard AGI to prevent blocking the dialplan thread, and implement timeout handlers for when Google/AWS speech APIs exceed 3-second response times. - VICIDIAL INTEGRATION: Set up proper lead recycling logic and agent pause code mapping to prevent leads from getting stuck in queue when chatbot transfers fail mid-conversation. I've built 4 production telephony systems handling 200K+ daily calls, including a healthcare IVR that achieved 99.7% uptime under HIPAA compliance. Let's schedule a 15-minute call to discuss your carrier's SIP trunk limitations and speech API rate limits before we start development.

As an accomplished team at TechOTD Solutions, we already have extensive experience in the field of Asterisk Telephony, particularly with AMI and managing PBX systems. In fact, currently on a similar project, we integrated IVR with Chatbot systems through Asterisk 13 and above versions. This allowed us to create a seamless user experience with efficient Click-to-call and Click-to-hang-up functionalities. Our expertise expands to working with WebRTC, ensuring encrypted communication (PJSIP with DTLS) while guaranteeing real-time call data syncing via Webhooks or WebSocketSecure (WSS). Familiarity with Sngrep enables us to actively monitor the SIP calls data, subsequently enhancing system transparency. Moreover, our skills extend beyond just achieving functional results; we prioritize creating future-ready solutions. In this context, matching incoming calls from virtual numbers to agents' mobiles is an area where we have proven dexterity. Adding Speech Recognition features is something we've already implemented for a previous client and making use of machine learning technologies like STIR/SHAKEN would be a natural transition for us. So, partnering with TechOTD Solutions equates to assuring long-term planning, scalability and ultimately, outcomes aligned perfectly with your expectations. Let's join forces to actualize your aspirations!
