The flow is straightforward: • I drop a plain text file into the bot chat containing one phone number per line. • As soon as the list is accepted the system rings every number at once (concurrency limit can be configurable in code). The calls will primarily go to the UK and USA, with occasional traffic to Ireland, so the underlying voice gateway must support those destinations. • When someone picks up, the first audio message I provide is played. If the callee presses 1, a second audio message plays, then the line is terminated. The bot should immediately send me a Telegram notification that includes the called number and a timestamp confirming they pressed 1. Anyone ...
My NEC SV9500 PBX refuses to come back online after a routine restart. The system hangs during boot; I do not see telephones registering and I’m not sure whether any error codes flashed on the console because I wasn’t watching closely. I need an engineer who knows the SV9500 architecture, maintenance commands, and PCPro (or equivalent) to: • Connect remotely (or guide me onsite) to diagnose why the call-processing software is not loading. • Identify and clear any database, card, or processor faults preventing a full start-up. • Bring the PBX to an operational state where extensions are live and calls flow normally. Acceptance will be when the system completes its boot cycle, endpoints register, and we can place internal and external calls without drops...
I have just incorporated a company in Ireland and now need a local phone presence. The goal is to activate an Irish virtual number (or an eSIM if that proves easier) that is registered to the business and, above all, can reliably receive incoming SMS and receive Voice calls (outgoing not that important) If you have direct experience dealing with Irish carriers or virtual-number providers and can complete this quickly, I’m ready to start right away.
I need a driven, articulate cold-caller to connect with residential homeowners, introduce the value of our roof inspections, and lock in qualified appointments for my field reps. You’ll work from my prospect lists inside our cloud CRM, dial through your own preferred soft-phone or our VoIP line, and keep concise notes on every conversation so the sales team walks in fully briefed. You must already know how to ease homeowners into discussing roof health, handle the usual price and timing objections, and confidently move the call toward a firm date and time. Expect to average several solid bookings per hour once you settle into the script; I’ll supply call guidelines, objection-handling cheatsheets, and live feedback during the first few sessions. Deliverables • Daily call...
Pay is $4/hour. Only respond if you agree to this pay rate. I run a small U.S.-based operation that needs hands-on help with day-to-day customer interactions. From 12 p.m. to 3 p.m. Eastern (that’s 12 a.m.–3 a.m. Manila time), I receive a steady flow of inbound calls and emails, plus occasional outbound follow-ups, and I want every contact handled promptly and professionally. During that three-hour window you will: • answer incoming calls and place quick outbound callbacks when required, • reply to customer emails in a friendly, concise tone, and • keep our live-chat widget active so no visitor waits more than a minute. A rock-solid, high-speed internet connection is essential—dropped calls or slow chat responses won’t work for us. I currentl...
I’m setting up a dedicated tele-calling environment and need an IVR system built (or customised from an open-source/cloud platform) that focuses on efficient call routing for both inbound and outbound traffic. Core requirements • Inbound calls flow through multi-level menus and reach the correct queue or agent without delay. • Every inbound conversation is automatically recorded and stored with searchable time/date tags. • Outbound campaigns must dial through the same platform so agents work from a single interface, with those calls recorded in the same repository. Scope of work You’ll deploy, configure, and hand over a production-ready IVR. I expect guidance on menu design, prompt management, real-time monitoring and a clean dashboard where my team...
I need a friendly, clear-spoken telecaller to handle English-language customer support over the phone. The calls will be routine, mostly general inquiries about our services and basic account questions—no technical troubleshooting or billing disputes. Here’s what I expect from you day-to-day: • Promptly answer inbound calls during agreed shifts and place the occasional follow-up call when a customer requests more information. • Listen actively, resolve the caller’s question on the spot when possible, or record concise notes in our CRM for any issue you must escalate. • Keep average handle time reasonable without rushing customers; empathy and clarity matter more than speed. • Maintain accurate call logs and update ticket status so the rest o...

I run an established business that relies on MyOperator to handle a high volume of incoming calls, and I need the IVR flow tightened up right away. Your main objective is to design or refine a multi-level IVR—think clear “Press 1 / Press 2” branching—then hunt down and resolve any routing or technical hiccups that stop calls from reaching the right telecaller. Here’s what I expect once you’re done: • A clean, multi-level IVR call flow published in MyOperator • Accurate call routing, forwarding, and department mapping so every call lands where it should • Missed-call and call-tracking features configured and tested • Smooth load distribution during peak traffic, with zero dead ends or loops I’m on a tight timeline, so the...
I already have a polished outbound script and an active Retell AI account—the only piece missing is your hands-on expertise. In a single 1–2 hour Zoom session you’ll share your screen and guide me through every click until a fully-functioning outbound calling agent is live and ready to dial. Scope of the call • Build the agent inside Retell AI from scratch, linking each branch of my script so the conversation flows naturally. • Configure appointment-setting logic specifically for sales consultations, with automatic collection of name, phone, and email. • Fine-tune voice settings (I’m flexible on gender) and any AI parameters needed for a human-sounding delivery. • Run at least one real test call to confirm dialogue flow, calendar integra...
I need a seasoned cold-caller who can confidently open doors with enterprise-level decision makers and position our full-stack capabilities—both web and mobile development—as the solution they have been looking for. The sole metric for success on this project is qualified lead generation; no sales closing is required at this stage, but every conversation should naturally pave the way for our internal sales engineers to step in. You will be working from a curated prospect list of mid-market and Fortune-level companies. Your job is to: • craft and deliver persuasive outbound pitches that emphasize how our integrated web and mobile teams shorten time-to-market and reduce total cost of ownership • uncover each prospect’s current digital priorities, project timel...
I need my Vicidial server configured for a fully agent-less “Press 1” outbound campaign that can run unattended. The list you will be dialing is a mixed audience of customers and cold prospects, so the system must handle large, varied datasets smoothly. Here is the flow I’m after: • The dialer places the call and immediately plays a promotional offer recording (I’ll supply the final WAV/MP3). • When the recipient presses 1, the call should be transferred in real time to a single phone number I will provide. • No agent will ever log in; the campaign has to launch, recycle and terminate automatically. You’ll take care of all campaign, list, and call-routing settings inside Vicidial, confirm audio formats, build the press-1 logic, and test li...
AI Voice Prompt Engineer (Real-Time Ordering System – NOT Chatbots) Body: We’re building a real-time AI phone agent for restaurants that takes full orders (like a human cashier). This is NOT a chatbot project. We need someone who understands: • real-time voice interaction (low latency) • turn-taking (no awkward pauses) • structured ordering flows (pizza, drinks, modifiers, upsells) • keeping conversations FAST, NATURAL, and ON TRACK What’s broken right now: • AI pauses too long • conversation loops / goes off track • responses feel robotic • ordering flow isn’t tight Your job: • design prompt structure + conversation flow • force clean step-by-step ordering (rails) • eliminate delays + overthinking responses &bu...
Our team—fewer than ten users in total—needs an efficient call-routing flow built inside Dialpad. I already have the seats created; what’s missing is the logic that decides who rings first, how overflow is handled, and how after-hours calls reach voicemail or an on-call mobile. Here’s the scope as I see it: • Map and implement the call-routing rules in the Dialpad admin console, using ring groups, IVR menus, or simultaneous/sequential ringing where appropriate. • Assign multiple roles so that a couple of us can act as admins while the rest remain standard users, without disturbing existing numbers. • Test each scenario—business hours, after hours, voicemail fallback—and document the settings so I can maintain them later. If you&rsquo...

I need a fully-functional auto dialer built for my company and I want it up and running fast. The core requirement is seamless VoIP service integration so my agents can place and receive calls directly through the platform without juggling extra software. Here’s what I expect: • A stable dialer application that can import contact lists, initiate outbound calls, and display real-time call status. • Direct integration with the VoIP provider I’ll share once we start, including proper authentication and fail-over handling. • A clean, web-based interface where agents can log in, see their queue, and record basic call outcomes. • All source code plus clear deployment and user documentation so my in-house tech team can maintain it afterward. If you&rs...
Asterisk tabanlı sistemimizi uçtan uca yönetebileceğim, Issabel’e benzer ancak güvenliği çok daha ön planda tutan yeni bir web paneli yaptırmak istiyorum. Kod tabanı temiz, modüler ve bakımı kolay olmalı; ek paketlere bağımlılığı minimumda tutmanızı tercih ederim. Panel tamamen Türkçe arayüzlü olacak, modern bir UI kütüphanesi (Vue, React veya benzeri) ile geliştirilebilir; arka planda ise Asterisk AMI/ARI entegrasyonu sağlam, rol-bazlı erişim kontrollü bir mimari isterim. Teslimatta mutlaka bulunması gereken ana modüller • Çağrı yönetimi ve kuyruk yönetimi • Kullanıcı / dahili yönetimi • IVR tasarımı ve yönetimi • Raporlama ve istatistik panelleri &bu...
