    I need a confident, clear-spoken caller to reach out to health-insurance agents and spark their interest in our pay-per-call lead generation service. Your task is simple: introduce the concept—live, inbound calls and secure a calendar slot for my closer to take the conversation further. There’s no hard sell or complicated pitch; you’ll be making warm introductions, answering a few top-level questions, and booking the appointment. If you already use a dialer, CRM, or VOIP platform, great—just export the basic call notes so I can track progress. I’m flexible on the actual calendar tool as long as the meeting lands smoothly in my team’s schedule. Deliverables I’m counting on: • Daily call log with contact outcome • Confirmed appointm...

    I have a custom-built VoIP system and now I need a conversational Voice AI agent fully integrated into it. The agent must: • answer common user FAQs with a natural, friendly tone • transfer callers to the appropriate live extension when requests fall outside its scope • record every call and automatically generate accurate, time-stamped transcripts for later review I’ll supply SIP credentials, call-flow diagrams and a small set of example dialogs. You will wire the AI logic into the VoIP stack, expose a simple dashboard or API so I can update FAQs on the fly, and ensure recordings and transcripts are stored in the format my compliance team already uses (WAV + JSON). Completion is accepted when live test calls on my staging server prove that: 1. callers get...

    I want my new AWS account configured to host a USA-based SIP trunk through Amazon Chime. The job includes creating or hardening the AWS environment, provisioning an Amazon Chime Voice Connector, assigning U.S. numbers, and enabling both inbound and outbound calling. The trunk has to register cleanly with our existing on-premise PBX and soft-phone apps, so please allow for SIP signaling tweaks, codec selection, and basic security (TLS, SRTP, firewall rules). Once the link is live, I’ll need brief documentation of the key settings so we can maintain it internally. Deliverables • AWS account prepared with least-privilege IAM roles • Amazon Chime Voice Connector fully configured and licensed for U.S. PSTN access • SIP trunk integrated and test calls completed (in...

    I want to replace the manual US Calling sales calls my team is making with a fully automated, AI-driven outbound dialer. The system has to plug straight into our existing CRM so that every call is launched from, and written back to, a single customer record. Core workflow • The dialer should pull a lead from the CRM, place the call automatically, open a tailored script, and capture everything the prospect says through real-time speech recognition. • Natural language processing must understand intent and sentiment, while AI-driven responses keep the conversation moving until a meeting is booked or a hand-off to a human rep is required. • Once the call ends, the transcript, outcome, and next-step task should save to the same CRM record without anyone touching a keyboard...

    I’m looking to have IP cloning / masking configured on my VoIP servers so we can distribute traffic evenly and keep call quality high. Load balancing is the sole objective here—this isn’t about anonymity or region-hopping, just making sure each incoming SIP session finds the least-loaded endpoint without exposing multiple public addresses. The environment is already up and running; what I need is the networking magic that presents one or more virtual IPs while the real servers sit safely behind them. If you normally work with tools such as iptables, nftables, HAProxy, IPVS, BGP anycast, or cloud firewalls, that’s perfect—use whatever combination you trust so long as it’s stable and keeps latency low. Because the phone queues are busy, I need this done ...

    I need to walk through, configure, and fully test an after-hours rule on my RingCentral call queue. Outside of business hours every call should go directly to voicemail, unless the caller flags it as urgent—in that case it must be forwarded instantly to the team lead’s phone. I want this built live with me so I understand each step. Once the escalation path is working, we’ll spend the remainder of the hour fine-tuning other features I use every day, specifically the IVR menu settings and the newer AI receptionist options. A short screen-share session is perfect; one focused hour should cover everything. Deliverables (completed during the call) • Functional call-queue rule that sends after-hours calls to voicemail • Verified urgent-call forwarding to the team...

    We are building a simple but reliable automation system designed for driving instructors. Driving instructors often miss calls while they are teaching lessons. When a potential student calls and the instructor cannot answer, that enquiry is usually lost. The goal of this project is to automatically recover those missed enquiries. The system should automatically respond when a call is missed, send a message to the caller, and notify the instructor if the caller is interested in booking lessons. This is not a prototype or experiment. We need a stable working system that runs automatically and reliably. Main Goal The main objective is to make sure driving instructors never lose potential pupils when they miss a phone call during a lesson. When someone calls and the call is not answered, ...

    I need an IVR built and configured so callers reach the right help fast. Its sole purpose is customer support, and it must offer three options in every relevant branch: an automated response for common questions, the ability to transfer to a live agent, and—when queues are long—a call-back request feature. You’ll design the call flow, record or synthesize the prompts, connect it to our existing SIP/VoIP trunk, and make sure the routing to our support team works flawlessly. I’m open on the exact number of menu levels; clarity and speed for the caller are what matter most, so feel free to recommend the simplest structure that still covers our FAQs and escalation paths. Final hand-off should include: • Diagram of the call flow with all customer touch-points &b...

    I need a complete IVR built and configured to streamline our customer-support line. The system must greet callers, then automatically route each call to one of five departments through a simple, voice-prompt menu. In addition to this core routing, I also want the IVR to trigger bulk messages (SMS or WhatsApp blasts) and hook directly into Meta Business Suite so our phone flows, social inbox, and chat automations all stay in sync. You are free to choose the underlying platform—Asterisk, FreePBX, Twilio, or a comparable cloud service—so long as it supports reliable call routing, bulk-messaging APIs, and Meta’s official integrations. If a ready-made template speeds things up, that is fine; the voice prompts, language, and menu logic must still be customised to our brand. D...

    I’m looking to partner with a reliable call-centre operation that can dedicate 1 – 5 agents exclusively to inbound customer support over the phone. All interactions will be in English, so clear diction and a neutral accent are essential. The agents will be the first point of contact for my customers, answering questions, resolving basic issues, and routing complex cases to my in-house team when needed. Average volume is modest right now, but I need a team that can scale quickly if call traffic grows. Core expectations • Live phone coverage during the agreed shift window • Courteous, solution-focused conversations that follow my brand guidelines • Real-time ticket or CRM updates so I always know the status of each call • Daily call logs and a conc...
