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 gearing up to launch a large-scale UK defence outreach campaign and need a turnkey solution that combines a robust predictive dialer with reliable VoIP service, all at a sensible cost. Here’s what I must have from day one: • A predictive dialer fully equipped with call recording, seamless CRM integration, customizable calling scripts and accurate AMD specifications so my agents never lose momentum. • VoIP lines that deliver consistently clear voice quality, scale smoothly as call volumes rise and come with round-the-clock technical support in case anything goes sideways during peak hours. If you can provide, configure and maintain this stack—preferably with quick onboarding, UK-compliant routing and transparent per-minute rates—let’s talk. ...
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...
Hi Vicidial is installed and working. Calls are being made too. Issue is i need to make calls to different campaigns. But it calls to one campaign.

I have created 2 campaigns medicare and final expense. It must dial both campaigns and i must receive calls on both numbers. Currently i can receive call on medicare campaign only. I need to fix this issue. So this job is only for them who can resolve this issue.

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...
Mam na własnym VPS zainstalowaną najnowszą wersję GoAutoDial 4. Potrzebuję specjalisty, który poprawnie skonfiguruje połączenie z moim dostawcą SIP trunk – Zadarma – tak, aby system bezbłędnie realizował zarówno połączenia wychodzące, jak i odbierał przychodzące. Zakres prac: • dodać i zweryfikować trunk Zadarma, • utworzyć odpowiednie dial-plany i reguły routingu, • przeprowadzić testowe połączenia w celu potwierdzenia jakości oraz stabilności, • wprowadzić ewentualne korekty konfiguracji serwera Asterisk wchodzącego w skład GoAutoDial. Środowisko obejmuje jeden VPS, więc konfiguracja dotyczy pojedynczego serwera. Po zakończeniu proszę o krótką instrukcję krok-po-kroku, abym mógł samodzielnie zarządzać podstawowymi zmiana...
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...
Project Title: Full Issabel 5 PBX Deployment: Installation, Trunks & Extensions Project Overview I am seeking a VoIP specialist to perform a complete installation of Issabel 5 on an AlmaLinux 8 cloud instance. Beyond the base installation, the freelancer will configure the initial telephony architecture, including SIP trunks for external connectivity and internal extensions for users. Detailed Scope of Work 1. Server Installation & Hardening Perform a clean installation of Issabel 5 on AlmaLinux 8 using the official net-install script.

I don't have FusionPBX installed on any server yet. You will install and setup fusionpbx on a server I will provide credentials access into. I want to be able to present a specific caller ID on every outbound call placed from my softphone. The softphone I will be using is Linphone, so everything you build must be fully tested from that app before we wrap up. What I need you to do • Configure the relevant SIP profile(s) and outbound route so that the number I supply appears consistently, regardless of the device extension that initiates the call. • Make any dial-plan or gateway adjustments required for a typical commercial SIP trunk. I have not fixed on one provider yet, so keep the setup provider-agnostic and document the few fields I will have to tweak once I decide. ...
I need an outbound voice AI that can pick up the phone, speak naturally with customers, and lock in service appointments without human involvement. The bot should dial leads from a list, confirm the customer’s need for our service, offer available slots pulled from an online calendar, secure the booking, and then push the confirmed appointment back to our CRM while sending the customer a confirmation SMS or email. Core flow • Call initiation through a voice gateway such as Twilio • Speech recognition and NLU (Dialogflow CX, Amazon Lex, Rasa, or similar) to understand the caller’s intent, handle clarifying questions, and gracefully manage “I didn’t catch that” moments. • Text-to-speech that sounds human; Google WaveNet, Amazon Polly or Micro...
I’m building a voice-driven receptionist that greets visitors or callers, listens to their questions, and replies with a natural-sounding voice. The core flow is straightforward: • Speech-to-text: Accurate recognition of English only is required for now. • NLP: Classify the intent and pull the correct answer when a caller asks about our business hours or location. • Text-to-speech: Respond with friendly, human-like audio. • Fallback: whenever the system is unsure, it should politely ask for more details rather than handing the call off or giving a canned line. I need the full stack—STT, intent handling, response generation, and audio playback—wrapped in a module that I can drop into my existing website widget today and expand to a phone line ...
I need a streamlined website whose sole function is to host and manage a voice-based AI call-center. The site will act as the control panel and public-facing entry point for customers who dial in, while giving me an admin area to configure and monitor activity. Core requirements • Automated responses: callers must hear natural-sounding, AI-generated answers that pull from a knowledge base I can update myself. • Live call routing: when the AI decides human help is needed, it should hand the caller off to a live agent instantly and log the transfer. • Voice channel only: chat or email may be added later, but right now the system must excel at telephone interactions. Technical expectations – Cloud telephony integration (Twilio, Plivo, or similar) for SIP/VoIP ha...

I need a fully-functional Google Voice account for 10 Users supported, registered from India but tied to a U.S. phone number, so I can place and receive personal calls to and from the States. The account itself does not yet exist and I have not picked a number, so part of the job is guiding me through—or handling—the selection of an available U.S. number that feels natural to me. Because Google Voice is officially unsupported here, you’ll have to take care of the usual hurdles (VPN, verification SMS to a real U.S. mobile, billing profile if required) and then hand over a clean login that I can secure with my own 2-step authentication. I plan to use the service interchangeably on both my smartphone and my laptop, so please configure and test calling on the Google Voice mo...

El objetivo es que el personal pueda manejar desde el PMS: • Registro de huéspedes: que cada check-in o check-out actualice automáticamente el estado de la extensión telefónica asignada. • Asignación de habitaciones: que al cambiar una habitación en el PMS se reprograme la extensión correspondiente en Asterisk sin pasos manuales. • Facturación y pagos: que las llamadas salientes e internas se registren en la cuenta del huésped y se reflejen en la factura final. Ya contamos con un software específico de gestión hotelera en la nube; requiero que el integrador trabaje sobre sus A...
