    My FreePBX install has suddenly stopped accepting any inbound calls. The configuration has not been touched for a while, yet every number on the system now rings out with no sign of life inside the PBX and no visible error messages. Outbound calls still work, trunks show as registered, but nothing is landing on the extensions. I need a seasoned FreePBX / Asterisk troubleshooter to jump in, trace what is blocking the inbound route, correct whatever trunks, inbound routes, firewall, or SIP settings are at fault, and get calls flowing again. Once it is working, I would like a brief note of what you changed so I can keep the system stable going forward. You will have full web GUI access on request; testing can be done live as this is a production box. I am in Australia, so I wi...

    VoIP Audio Reliability Fix

    Our production VoIP app runs on Kamilio/Asterisk is suffering from three clear symptoms: call dropping, audio quality issues. The trouble appears only on a fraction of calls rather than every connection, so I need someone who can track down the underlying triggers—whether they sit in the signalling layer, jitter buffer, codec choice or network traversal logic—and then eliminate them. You’ll start by reviewing the current SIP/WebRTC stack, server logs, packet captures and any client-side metrics I provide. From there, pinpoint the root cause and apply code, configuration or infrastructure tweaks to stabilise audio flow. Deliverables • Detailed diagnosis outlining where packets or media streams fail • Fixed client or server code / configs ready for ...

    I need a fully-functional outbound voice agent that plugs straight into my VICIdial / GoAutoDial stack (Asterisk) and dials our CANADIAN leads through the SIP trunk we already use. Once connected, the bot must carry the entire conversation in a friendly, relaxed tone—answering common questions, keeping to our compliance wording, then moving naturally into a soft-close or handing the call over to a live agent when the prospect is ready. Key things I will be testing for: extremely low latency between speech-to-text, LLM response and text-to-speech; barge-in so the prospect can interrupt without awkward pauses; sentiment and intent tracking so the call flows feel human; and a clean handoff of every outcome, recording and transcript back into VICIdial and our CRM.

    ...cloud-based SIP PBX. The VPN will serve purely as a private communication network, not just remote access, so every endpoint—office phones, softphones, and any future branch sites—must pass voice traffic through it. On the PBX side I only need reliable call routing and forwarding at this stage; features such as voicemail, recording, or conferencing can remain optional add-ons if the platform you choose already supports them. Feel free to propose Asterisk, FreePBX, 3CX, FusionPBX, or another cloud offering—as long as it can live behind the VPN, handle SIP trunks cleanly, and scale without headaches. Deliverables (kept short and specific): • Deploy and configure the VPN with strong encryption, user authentication, and clear subnet planning...

    I need a working call-automation flow th...Google Calendar / Outlook once the prospect shows interest A functional prototype is enough for the first milestone—I want to hear the bot live on a test number, handling the two tasks above smoothly and handing off qualified leads to a human. Please show me past work that proves you have already built voice-AI or n8n call workflows. Mention which telephony stack you prefer (Twilio, Plivo, Asterisk, etc.) and any speech-to-text / LLM services you plan to integrate. Success for this project means: • Natural-sounding conversation with <2 sec latency • Appointment details correctly logged with contact info • Call recordings and transcripts saved in my CRM If you can deliver within those parameters, I’m r...

    ...looking for an engineer who can stand up a production-ready Kazoo cluster across eight fresh CentOS 7 servers. The platform has to carry roughly 50,000 concurrent calls while staying lean on bandwidth, so efficiency and proper resource tuning are essential. My top priority is a rock-solid call center component with dependable call-termination routing. Around that core, I also need: • Multi-tenant PBX functionality so each customer lives in its own space. • A clean, web-based GUI for both users and admins. • Self-service user registration plus zero-touch auto-provisioning for common SIP endpoints. • End-to-end subscription handling that mirrors the advanced flows found in Zelle and CashApp. • A single “one-click” script that genera...

    I need a complete Asterisk-based outbound platform fine-tuned for high-volume marketing calls. The core flow is simple: the system auto-dials a list, detects whether a human picks up, skips voicemail instantly, and routes every live answer straight to a waiting agent. Essential features • Voicemail logic – detect voicemail reliably, bypass Google Voice screening by having the dialer state my company name when prompted, and, if no human answers, automatically redial the same number up to 4 times during the campaign window. • Live transfer – answered calls must land in a real-time agent queue (SIP soft-phones or WebRTC, whichever you prefer to configure). • API hooks – integrate both an Email marketing service and the Doxer API so that contact...

    I need a purpose-built module for Issabel that turns the PBX into a fully featured public-address engine. The add-on must let me trigger live or pre-recorded broadcasts to any SIP endpoint registered as a PA speaker, schedule automated messages, and issue one-click emergency alerts that can override all ongoing audio. Beyond simple paging, I also want two-way talkback so selected devices can return audio to the control room. Audio quality matters; the module has to negotiate and play high-quality codecs such as Opus or G.722 whenever endpoints support them, while falling back gracefully to standard G.711. A browser-based dashboard should give me at-a-glance status of every PA device—online/offline indication, current stream, volume level—and provide controls to group e...

    I have a Grandstream UCM6300A that is ...inbound call never reaches the phones—there’s no ring at all. Here’s what I already know • The SIP trunk shows as “registered.” • Inbound routes are set up and look correct. Despite that, calls still fail to ring, so I’m clearly missing a detail somewhere (DID pattern, NAT, firewall or similar). I need someone who understands Grandstream UCM-series quirks to: 1. Remotely inspect the PBX configuration (trunk, inbound routes, extensions, firewall / NAT). 2. Pinpoint and resolve whatever is blocking the ring. 3. Provide a short summary of the fix so I can repeat it if needed. Screen-sharing or a quick SSH/HTTP session is fine; I’ll supply access. Once your tweaks let the pho...
