My Outlook desktop client refuses to send or receive mail reliably and throws frequent error messages whenever I try. The account is tied to Microsoft 365, so it should behave like an Exchange mailbox, yet messages fail and experience consistent undeliverability problems. Here is what I need from you: • Pinpoint the root cause of the send/receive failures—whether it’s profile corruption, service-side throttling, an add-in conflict, or something else. • Apply the fix remotely (PowerShell, Outlook profile rebuild, cache reset, or any proven method you trust) and show me the steps so I can replicate them later if required. • Confirm that messages flow both directions instantly after the repair and that no sync errors remain in the Sync Issues folder. • Provi...

Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PHP-FPM, databas...

Our IPECS UCP is already in place and running well, but the firmware is lagging behind the current stable release. I need the system brought up to date with a clean, verified firmware-only upgrade; no hardware swaps or network re-engineering are planned at this stage unless the new software requires a minor tweak. You’ll begin by confirming the exact model and present firmware build, take a full backup, then apply the latest approved firmware from Ericsson-LG. After the flash, I expect you to restore all existing configurations, run functional tests on call routing, voicemail, and any licensed features, and provide a brief report that lists the version numbers, tests performed, and confirmation that the upgrade passed without errors. Deliverables: • Verified system backup be...

Потрібна регулярна технічна підтримка для вже запущеного корпоративного сайту. Основний фокус — постійний моніторинг та підготовка звітів про працездатність ресурсу.

Issue: - My captive portal was originally configured with hotspot.inetwall.com. - I have migrated to because the ".com" domain has expired. - I updated the configuration files, but users are still being redirected to the old ".com" domain, or the captive portal still references ".com" during the login/redirect process. - I need the entire captive portal to use only, with no remaining ".com" references.

I need a specialist who can stand up an outbound ViciDial instance and connect it cleanly to Twilio so my customer-support team can start taking and placing calls right away.

Essential features • Call recording enabled on every leg of the call, saved with logical file names and dates. • Automated call distribution so incoming queues and outbound callbacks are routed evenly across agents, with simple skill-based routing rules. Your work will include installing or hardening ViciBox/Asterisk, configuring Twilio Elastic SIP Trunking, setting up the dial plan, test campaigns, agent log-ins, and showing me wher...

I need a complete 3CX installation configured for a very small team of 5 – 10 users. Everything must run smoothly for both inbound and outbound calling within Australia, and I want to keep monthly costs as low as possible. Scope • Provision and configure 3CX (cloud-hosted or on-prem—whichever delivers the lowest ongoing cost without sacrificing reliability). • Source and activate Australian local phone numbers only; no toll-free or international numbers are required. • Create extensions, queues, and ring groups so each team-member can take and place calls from soft-phones or desk phones. • Upload and map my pre-recorded IVR prompts and build the call-flow menu accordingly. • Set up voicemails, basic reporting, and fail-over rules; call recordin...

I Want to build a lightweight background service for Windows 11 that quietly blocks any websites or desktop applications I specify—typically the distracting ones such as social-media, streaming, or gaming platforms—while leaving everything else untouched. This run as a persistent service that restarts automatically with the operating system. This project is inspired by a freedom like productivity software Scheduling is fully custom: I can create multiple plans, each with its own time slots. Outside a tiny de-activation window that I set (for example, 07:00-07:05), no one should be able to modify or disable the rules; during that window I alone can lift restrictions or adjust settings. New sites or apps can be added to the block list at any time. Because I want the tool to...
