Hello, With my extensive experience in AI and Automation, I believe I am uniquely equipped to bring your vision for an inbound call center platform to life. My abilities align perfectly with your project's requirements. I have the relevant expertise in SIP Trunking, WebRTC, REST APIs, and the potential stacks such as Asterisk, Freeswitch, Twilio which we can use. Additionally, the proficiency of deploying scalable systems on the cloud and clear documentation are strengths I bring to the table that would ensure a seamless handover. Moreover, my background in designing systems running on autopilot resonates well with your desired easy-to-manage call center platform features. My strategies in AI Lead Generation Systems which involves automating qualification and follow-ups can be leveraged to enhance skill-based routing and real-time dashboard statistics of your call center system. To demonstrate my commitment to delivering high quality work, I pledge to provide you with an installable package or Docker image that deploys the full system with a single command; Source code available through a private Git repository with concise READMEs, schema diagrams and inline comments; An end-to-end test suite showcasing successful calls entering the queue, being routed to agents, recorded securely. Additionally, a live demonstration on my staging server before final hand-off is guaranteed. Let's get started! Thanks!

Hello, I hope you're doing well. I can build the ACD and recording platform around Asterisk, Docker, WebRTC, and REST APIs, with supervisor controls included. I'd start by defining SIP flows, queue rules, recording retention, and the deployment schema. The test suite would cover a call from queue entry through secure storage. Could we have a short conversation about trunking, scaling, and the single-command deployment target? Thank you, JennyCreation

One decision drives the whole architecture: do you already have a SIP trunk provider and DIDs, or should I recommend and provision one?

Hi You're building an inbound call center platform emphasizing ACD and tamper-proof Call Recording. The core challenge is low-latency integration of skill-based routing and secure recording storage. Leveraging Asterisk for telephony, with WebRTC for agent endpoints, and RESTful APIs for integrations is a strong approach. I've built systems using these technologies, notably enhancing call efficiency with Asterisk SIP trunking and secure recording. Your focus on a cloud-deployable, supervisor-friendly solution without the command line is spot on. I have the expertise to bring this vision to life. Let's dive into the architecture to ensure it meets and exceeds your needs. Thanks, Jonathan

Hello, Warm greetings from Syndell! We understand you're building TelesalesOS - a production-grade Telnyx-powered contact center with browser softphone, ACD routing, supervisor monitoring, and call recording. This requires far more than basic voice API integration; it demands deep expertise in call legs, SIP/WebRTC registration, webhook reliability, and atomic agent state management. We approach these mission-critical workflows as event-driven architectures built with TypeScript, Node.js, PostgreSQL, and cloud infrastructure. Our team specializes in exactly this class of telephony integration. What's your expected scale for concurrent agents, and do you have specific compliance or recording retention requirements we should architect for? We are a full-service software, AI, and digital-marketing agency with 5-star reviews on Clutch and GoodFirms, counted among the top-rated companies for our services on Freelancer.com. We would love the chance to discuss your vision in more depth and demonstrate, with examples from our portfolio, why we are the right fit. Hoping to speak soon. Thanks! PS: The final time and cost may be subject to change based on our discussion.

Hi Building inbound call center software with a greenfield Telnyx implementation calls for strong expertise in cloud telephony and integration. The primary technical challenge here involves setting up a reliable ACD system that allows configurable routing and agent selection, while maintaining the separation from the reservation process. This is effectively managed using solutions like Supabase/Postgres for data integrity and Redis for real-time performance enhancements. I bring experience in developing scalable VoIP and WebRTC-based applications, having recently built a cloud-native call routing platform utilizing Asterisk PBX and RESTful APIs for dynamic configuration. I appreciate your approach of keeping routing logic flexible and separate from other processes, ensuring adaptability as requirements evolve. I can help you architect this solution, ensuring compliance with regulatory standards for secure call recording and data handling. Let's get in touch, and I can walk you through the tech stack and architecture that successfully supports your needs. Thanks, Oswaldo

Hi , I'm not a Telnyx WebRTC softphone specialist, and your spec rightly wants one. Where I'd add real value is the layer most bids will underbuild: multi-tenant security, webhook reliability, and 7-year recording retention. Relevant work: - Event-driven webhooks: rearchitected a core platform to purely event-driven (Go→Rust) at Picogrid — idempotency, out-of-order handling, dead-letter, state reconciliation are the exact failure modes I design for - Multi-tenant isolation: identity-scoped access under FedRAMP High/HIPAA, server-side authz, no cross-tenant leakage — the discipline behind Supabase RLS - Recording archive: S3 Object Lock, versioning, restricted IAM, integrity hashes, legal holds, expiring playback URLs - compliance-as-code is what I do - Auditable ledger: integer minor units, every routing/supervisor action logged I'd recommend Redis alongside Supabase for atomic agent reservation and presence heartbeat/expiry — that's a locking problem, not a query. Honest fit: pair me with your Telnyx/front-end dev. I own the reliability, security and compliance backend; they own the softphone and ACD. How I'd start: the webhook ingestion + reconciliation core and the S3 retention pipeline — the two pieces that are painful to retrofit. Best, Zach N.

Hi, New on Freelancer — 20 years of development experience behind us. We're taking our first few projects here at a fraction of our normal rate purely to build our review history. You get senior agency work at junior pricing; we get a review. Straight trade. integrating WebRTC with your existing stack can sometimes introduce latency issues due to network constraints. I'd start by assessing the current network setup for bottlenecks. Can you share access to your GitHub repository so I can review the existing codebase?

@dvcontact
