My RingCentral business line is being marked as “SPAM” when it shows up on customer phones and nothing I have tried has cleared the tag. I have already: • Registered the number with the main analytics services (including Hiya) • Opened several cases with RingCentral support and followed every suggestion they offered—none of them worked. What I need now is someone who has actually removed this label before and can do it again for my number. Success means that calls placed from the line no longer display any spam or scam warning on the major U.S. mobile networks (AT&T, T-Mobile, Verizon, etc.). I will verify this on multiple devices before releasing payment; no partial milestones. Deliverable • Confirmed removal of the spam/scam label on the numbe...

I need a clean, fully-functional Windows Server 2025 virtual machine running on my existing TrueNAS Scale host. The VM’s main job is straightforward application hosting, so top-end 3D performance is not required; the Quadro 2000 only has to provide a smooth, basic graphical interface once passed through.

I’m looking for a Europe-based freelance IT engineer who can design, install, and maintain a reliable Local Area Network focused on routers and switches. The cabling is already in place, so I need someone who can come in, assess the existing environment, recommend any additional hardware if required, configure everything for optimal performance, and make sure the network scales easily as our headcount grows. Once the core is live I’d like occasional proactive maintenance and rapid, on-call troubleshooting when issues pop up. Familiarity with the major enterprise switch and router vendors is essential, and I’m happy to work with you on firmware standards, VLAN segmentation, and best-practice documentation. Deliverables I expect: • Detailed implementation plan (inclu...

I’m rolling out a new Local Area Network in several European offices and need the Wi-Fi layer deployed end-to-end. The scope centres on network setup and ongoing maintenance, with a focus on installing, configuring, and optimising access points so every workspace enjoys seamless coverage. You will start with a short remote planning call where I provide floor plans and current cable routes. From there, you’ll advise on access-point counts, placement, channel planning, and any controller requirements, then be hands-on on site (or coordinate local hands) to mount, patch, and bring the APs online. I’m happy to work with whichever enterprise hardware you’re most comfortable with—Cisco, Aruba, Ubiquiti UniFi, or similar—as long as the final network meets roam...

Our production file-share runs on AlmaLinux with Samba and I’m seeing sluggish transfer speeds that vary wildly across mixed file types. I’ve ruled out basic network congestion, so the bottleneck is almost certainly in the current Samba configuration. Here’s what I need: • Pinpoint and eliminate any configuration errors that could be throttling throughput. • Tune and related system parameters for consistently fast transfers of both large binaries and many small documents (the workload is truly mixed). • Document each change, why it was made, and the performance delta observed after the adjustment. Acceptance criteria: after your tweaks, average transfer speeds for a representative mixed-file batch must meet or exceed gigabit-line expectations,...

Title: Developer Needed to Build Monitoring Platform Using EZVIZ API / SDK (Fixed Price Project) Description Hello, My name is Alex. I run a security company operating a monitoring center. We have many EZVIZ cameras (model H9C) installed across multiple client sites. Currently, these cameras are installed without any NVR on the client sites. We access them remotely using EZVIZ PC Studio, which is mainly designed for home or small installations and not suitable for professional monitoring. Important note: EZVIZ H9C cameras do not provide RTSP streams, so the system will likely need to use the EZVIZ Developer Platform (Cloud API / SDK). What we want to build We want a centralized monitoring platform where our operators can monitor cameras from many different sites. Ideally, the sys...

I want my Ubuntu server configured as an OpenVPN host that lets me and a small team (fewer than ten users) connect securely from anywhere. The goal is straightforward: reliable, encrypted remote access without having to worry about manual key generation, firewall tweaks, or routing issues each time we add a new device. Here’s what I expect at the end of the job: • OpenVPN installed and running on my existing Ubuntu server (latest LTS). • User-friendly client configuration files or .ovpn bundles for up to ten devices, plus a quick guide so I can generate more later if needed. • Firewall and IP forwarding rules adjusted so traffic is tunneled safely while the rest of the server’s services keep working as they do now. • Basic security best practices ap...

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 ...

My wired Ethernet network has stopped working, and I need a skilled technician to get it back online quickly. I’ve already ruled out basic cable swaps, so I’m looking for someone who can: • Diagnose the root cause of the outage (switch, patch panel, NIC, or configuration). • Walk me through any testing steps I should perform on-site (ping, traceroute, link-light checks). • Provide clear, step-by-step instructions or remote-session support to restore connectivity. • Verify that all connected devices regain stable internet and LAN access once the fix is applied. • Offer a brief preventive checklist so I can avoid the same issue in the future. I can share photos of the rack layout, current IP scheme, and error messages from the router and switch interfac...

I need a reliable person located in the United States who can keep my personal laptop safely at their place, plug it in to power, and turn it on once every day. There are no special tasks to run—simply boot it up, confirm it’s online through your regular, stable internet connection, and let it sit for a moment so remote services can sync. After that, you can shut it down again. What matters most is trustworthy, secure storage in a clean, smoke-free environment, and the discipline to power it on daily at roughly the same time. No dedicated network, VPN, or extra equipment is required on your side; a standard home broadband line is sufficient. If you can provide a safe spot, dependable internet, and consistent daily availability, let’s talk about the hand-off logistics an...

I had NordVPN running smoothly on my new Ubuntu laptop for the first few days, but after tweaking some network settings on the machine the VPN refuses to reconnect. I would like someone to: • diagnose what I changed in Ubuntu’s network stack that is blocking NordVPN, • put those settings back into a clean, working state (command-line or NetworkManager), • verify that my home router is forwarding traffic or configured correctly so the VPN handshake is not being blocked, and • give me a short walkthrough so I understand how to avoid breaking things again.
