I need a fresh VPS management server spun up and configured from scratch, then have FreePBX installed, fully secured and connected to my account. The VPS itself is not yet provisioned, so I will rely on you to recommend the most appropriate OS—CentOS, Debian or Ubuntu—explain why, and then handle the entire build. I do have a few custom requirements inside FreePBX (not a plain-vanilla install), so once the basic stack is running I will share the detailed dial-plan tweaks, trunk settings and any extra modules I need. Key deliverables: • Provision and harden the VPS with your recommended Linux distro • Install the latest stable FreePBX and Asterisk • Configure trunks, routes and SIP credentials for so calls in/out work straight away • Apply my sp...
I need a reliable virtual cold caller to reach out to a targeted list of people who are planning a residential move and briefly introduce our packing service. You will be dialing 100–200 numbers each day through your own VoIP system, keeping every conversation recorded so I can review call quality and compliance at any time. Your day is simple: connect, confirm interest, ask the qualifying questions I provide, and forward the contact details of anyone who wants a quote. No pricing, no hard-selling—just clear, professional qualification. Because this campaign is critical to our sales funnel, I expect: • More than three years of hands-on cold calling or lead-qualification experience • Proven history of recording every call and supplying a concise daily report (dial...
I have a Cisco Layer 3 managed switch running on its default IOS configuration, and I want its performance tuned for noticeably faster inter-VLAN traffic and lower latency across the network. At the moment we have several VLANs in place, but routing, spanning-tree parameters, and QoS queues have never been optimized. Traffic occasionally bottlenecks when large file transfers coincide with VoIP or video meetings, so the goal is to streamline the switch’s internal processing and link utilization to improve overall throughput. Here is how I see the engagement unfolding: • Review the current running-config (I will supply the sanitized text dump). • Recommend and apply adjustments to VLAN design, SVIs, dynamic routing or static routes as appropriate, STP settings, EtherChann...

We are looking for a freelancer with hands-on experience in Asterisk, telephony, and SIP setup to support us on a short-term project.
I’m rolling out a new payments stack and need a specialist who lives and breathes PSP integrations. The goal is to wire several providers into a single cashier, route transactions intelligently (cascading / fail-over), and do all of it through the Praxis platform so my forex operation can process smoothly across multiple jurisdictions. Here’s the landscape you’ll be walking into: we already have merchant accounts waiting, a partial Praxis setup, and a development team that can expose any hooks you need. What we do not yet have is the deep PSP know-how to stitch everything together—gateway APIs, alternative payment methods, risk rules, card presentment logic, the works—and then tune it for high-risk traffic without throttling approval rates. Your brief is str...
You’ll be taking incoming calls that I transfer to you, introducing yourself as my assistant, and providing employment references for two former staff members who are now at separate companies. I will supply everything you need—reference details, concise company scripts, and a quick-reference FAQ—so you can answer confidently and consistently. Beyond the calls, I’ll rely on you to: • Monitor the dedicated email inbox, respond or flag items that need my attention, and keep it tidy. • Slot any follow-up interviews, verification calls, or reminder meetings directly into my calendar. • Keep a brief call log and email me a same-day summary of each interaction, noting any next steps. A quiet workspace, reliable phone line or VoIP app, and clear spoken Eng...

At the heart of the assignment are two complementary roles: Sales Supervisor Your focus is on developing clear, data-backed sales strategies for both brands. I will rely on you to map the funnel, set realistic KPIs, choose the right outreach tools, and fine-tune messaging so the front-line callers can move prospects smoothly toward a close. Salesperson • Cold call qualified prospects drawn from my lead lists and any you source independently. • Follow up persistently by phone, email, or SMS until a firm yes or no is recorded. • Close the deal, secure signed orders, and hand the customer to onboarding. Telecommunications experience is essential; knowled...
I need reliable cover for 15-20 inbound calls a day that come through our small MSP help-line. Every call is a technical support request, limited to network-related issues such as “my Wi-Fi dropped” or “the router’s lights are red.” I only expect basic troubleshooting—verifying connections, guiding the user through a reboot, checking whether a known outage is in place—and, when the quick fixes don’t work, booking the caller into our ticketing calendar for a remote or on-site session. You will: • Answer during my published service window (Mon–Fri, 9 AM-1 PM EST). • Follow the provided call-flow script, log the interaction in Freshdesk, and assign a priority tag. • Schedule the next step in Google Calendar with the co...

I need help running a steady stream of outbound cold calls for a sales-focused campaign. You’ll work part-time, contacting prospects from the lead list I provide and following a ready-made script that introduces our product, gauges interest, and, when possible, secures an appointment for my team. The rhythm is simple: log in to the dialer during the agreed hours, work through the calls, note each outcome in the CRM, and flag hot leads right away. You’re free to add your personal touch as long as the core talking points stay intact. What I’ll hand over: • A detailed script, objection-handling tips, and call flow • A vetted list of contacts with phone numbers and basic notes • CRM access (HubSpot) and a VoIP dialer account What I need back: &...

I have an Asterisk instance that needs a fully functional IVR linked to our SIP trunks. The core requirement is simple: callers should be greeted, routed through a concise menu, and seamlessly bridged to the correct internal extensions or external numbers. I already have the server and SIP credentials; what I need is your expertise in writing the dial-plan, recording or loading the voice prompts, and making sure calls flow reliably both ways. Configuration must be clean, well-commented, and resilient so future menu changes are straightforward. Once everything is in place I’ll run live tests with you to confirm: • IVR menu plays correctly and follows the designed call flow • SIP trunk registers and handles inbound and outbound calls without drops or codec issues •...

My 5G home connection is delivered through an Archer NX200 5G router and, like many 5G plans, it sits behind CGNAT. Because of this, I cannot reach my internal network from the outside world. The goal is clear: Remote Access. I need to log in reliably to my Computers, Smart Home Devices and Security Cameras, as well as a small PBX and a Draytek firewall. Dynamic DNS is already running with NOIP, yet CGNAT keeps every incoming request from ever reaching the LAN. What I’m looking for is a practical, reproducible way around that limitation: • A working solution that lets me initiate inbound connections (HTTPS, SSH, VoIP, etc.) from anywhere. • Detailed, step-by-step configuration on the Archer NX200 5G and any additional hardware, tunnel, or cloud service you recomme...
I have an STC 5G connection running on a TP-Link Archer NX200 router. The connection is behind CGNAT, meaning I do not have a real public IP. I am looking for an expert to provide a solution to get a Dedicated Static Public IP so I can remotely access my internal network (Router management, SIP devices, etc.) using my noip DDNS Conditions: I cannot upgrade to a Business SIM card. I do not want to run a local PC 24/7 as a bridge. I just need a working Static IP solution that routes traffic from the outside directly into my local network. Please propose your method and how we can implement i
I need an expert who knows the Panasonic KX-NS100 inside out to take over ongoing maintenance and, more urgently, to hunt down stubborn routing problems. At the moment we are plagued by ghost calls, fake trunk activity and sporadic audio drop-outs that confuse users and clog the logs. These symptoms point to deeper call-routing faults, so I’m looking for someone who can dive straight into ARS tables, COS settings, SIP trunk parameters and firmware quirks to pin down the real cause, clean it up and stop the phantom traffic for good. You’ll be given remote access via VPN or TeamViewer during our business hours so you can trace packets, watch live call traffic and adjust the configuration in real time. Once the issues are eliminated I’d like concise documentation of every...
