    I need an end-to-end implementation of Zoom Contact Center. The project covers designing, configuring, and launching the full environment so my team can handle Live chat, Voice calls, Video calls, traditional Email tickets, and inquiries triaged by the Zoom Virtual Agent—all from the same pane of glass. Scope Right now I have Zoom licences in place but no contact-center instance configured. I want you to build the entire workflow: inbound routing rules, IVR menus, chat and video queues, email hand-off, skill-based distribution, and the knowledge base that powers the Virtual Agent. SSO must be enabled and user roles defined so agents, supervisors, and admins see only what they need. Basic dashboard and historical reports should be ready from day one.

    AI Voice Agent for Sales
    6 dias left
    Verificado

    I’m ready to deploy an AI-driven voice agent built on the stack that can take real-time phone conversations off my plate and keep our sales pipeline moving. The mandate is clear: • Purpose: pure sales support—no generalized customer service scripts—so every interaction must prioritize moving prospects toward a close. • Tasks: the agent needs to qualify inbound leads against a short set of questions I’ll provide, automatically schedule or transfer hot prospects, and run friendly, timely follow-up calls that nudge colder leads back into the funnel. • Call direction: it should handle both inbound and outbound calls seamlessly, switching context without awkward hand-offs. I’ll supply brand guidelines, objection-handling notes, and CRM API key...

    I need a fluent English speaker who can jump straight into handling both inbound and outbound calls with our business partners. The role sits at the intersection of customer happiness and light technical troubleshooting, so you’ll spend most of your day guiding partners through product-related questions, documenting each interaction in our CRM, and making sure every conversation follows the script and brand tone I’ll provide. Because you’ll be the first voice many partners hear, I’m looking for someone who stays calm when lines are busy, keeps notes organised, and can translate a technical answer into plain language on the fly. Prior technical support experience is essential—if you’ve ever walked someone through a configuration step or explained why a...

    Ubuntu Airtel SIP Initial Setup
    5 dias left
    Verificado

    I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

    My Panasonic Ns500 PBX sits on but cannot “see” the rest of my network. Everything else flows through a FortiGate 60F firewall, a FortiSwitch 424E-Fiber core, and a FortiSwitch 124F-FPOE at the edge. I need someone to shape the network so this Panasonic box can handle VoIP communication smoothly. What I already know • The PBX will run pure SIP. • Dedicated VoIP rules on the FortiGate are required; simple, generic access is not enough. What I need from you • Review the current FortiGate policy set, VLAN layout, and switch port profiles. • Create or adjust firewall rules, NAT, and any SIP ALG or helper settings so that SIP registration, signalling, and RTP streams pass without one-way audio or dropped calls. • Tag or untag the appropriate swi...

    I’m looking for a reliable ViciDial pro who can jump in each day and keep my dialer running smoothly. The core of the job is straightforward but must be done consistently: • Run the standard performance and list-based reports I specify, download them, and drop them in our shared folder before end of day. • Import new lead files (CSV) as they arrive, map fields correctly, and verify the list is live. • Check that every active campaign’s leads are sitting in the hopper in the right quantities so agents never run dry. If a hopper is empty—or about to be—top it up and ping me in Slack. Everything is handled remotely; you’ll just need a stable connection, a headset for quick follow-up calls if questions arise, and solid familiarity with the Vic...

    I want to put an always-on AI voice agent in charge of one thing only: generating brand-new cold leads by telephone. I will provide the target market, ideal-customer profile, and high-level talking points; you build, train, and deploy the agent so it can dial prospects, hold a natural conversation, qualify interest, and pass every promising contact straight into my CRM. The agent must: • sound human and handle common objections in real time • record, transcribe, and store every call • schedule callbacks or meetings on my calendar • respect local calling regulations (TCPA, GDPR where applicable) I’m comfortable with Twilio Voice, Dialogflow, ElevenLabs, GPT-4, or any similar stack—as long as call quality and scalability stay top-tier.

    I need an experienced telephony engineer to bring up a new IVR on our Asterisk-based server that will answer calls coming in on both a SIP trunk and a PRI. The core requirement is a clean, dependable call-routing tree—callers should reach the right destination every time—with call recording and basic, built-in reporting turned on from day one. Environment • Linux box already running Asterisk (remote SSH available) • One SIP trunk + one PRI (credentials and circuit details ready) Scope of work 1. Configure the IVR in Asterisk, activate call routing options, and confirm that both trunks follow the same logic. 2.
