I am ready to move straight into the Execution and Testing phase of ITSAR for a new telecom product and need a specialist who can see the process through to formal certification. Here is what the engagement will look like: • Hands-on execution of ITSAR security tests focused on the product’s network security stack and its software layer. You will be working directly on live units in a Linux-driven environment, so solid command of networking, penetration techniques, vulnerability assessment tools and telecom-grade hardening practices is essential. • Close coordination with NCCS and the relevant Telecom Security Test Labs (TSTLs). I will involve you in all technical calls and data exchanges; you will help interpret lab feedback, tweak test cases, and make sure every issue ...

I need a test engineer who can run comprehensive manual functionality tests on a mobile application before its next release in Singapore. The job revolves solely around hands-on, exploratory and scripted testing—no automation or performance work is in scope. Your work should uncover functional defects, edge-case issues and any regressions that could affect end users on common mobile devices. Mobile Device & Network Testing Conduct pre-launch and field testing for mobile devices, including smartphones, FWA (Fixed Wireless Access) routers, and IoT devices. · Perform stationery and mobility tests for 5G/4G LTE/VoLTE/VoWiFi/5G across different network conditions. · Analyze network KPIs, coverage, throughput, call drop rate, handovers, and VoNR-MOS ...

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...

I have a fresh install of the Vibe server application running as a VoIP bandwidth optimizer and I’m stuck at the configuration stage. My immediate goal is to finish the initial setup, fine-tune the optimizer settings, and then bring a VoIP gateway online on a public IP so calls flow end-to-end without drops or quality loss. A screenshot of the current network layout is attached for reference. Here’s what I need: • Apply the right Vibe configuration parameters so it actually starts shaping traffic efficiently. • Map the public IP, open the correct SIP/RTP ports, and register the gateway so it’s reachable from outside the LAN. • Walk me through any CLI or web-GUI steps I’ll need to repeat later (firewall rules, NAT, codec or QoS tweaks). •...

I need a technician to run a small bundle of Cat6—2 lines—through an industrial unit here in Badlapur. The tray routes are already installed and clear, so we can focus purely on pulling the cable, dressing it neatly, and crimping RJ-45 connectors on both ends. The job will be considered complete when: • All cables are laid end-to-end through the existing pathways without kinks or damage • Each termination is crimped to T568B and labelled • A basic continuity/short-check with a cable tester shows a pass on every line Please bring your own crimping tools, tester, and consumables. I’ll supply the Cat6 bulk cable and wall plates. Let me know your earliest availability and how long you expect the work to take so I can arrange site access in advance.

I need a complete 3CX instance brought online for an Australian operation today—ideally within one to two hours of kickoff. The build must include a working SIP trunk (no provider pre-selected, so feel free to choose the quickest reliable option), inbound and outbound calling, and an IVR that plays my already-prepared pre-recorded messages. Beyond this first deployment, I regularly set up similar centres in the UK, AUS, and USA, so a smooth, repeatable process is important. Deliverables • Fresh 3CX install (cloud or on-prem, your choice) • SIP trunk fully registered and tested for Australian DIDs • IVR configured to play supplied audio prompts on both inbound and outbound flows • User extensions created as required and test calls recorded as proof of s...

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. About 20 agents will log in daily, so the system must be sized and tuned for that load, including concurrent calls, proper carrier failover, and responsive web interfaces. 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 need Microsoft Teams configured so my team can run reliable group calls without hiccups. The focus is purely on the set-up side—no custom coding or feature development, just making sure call routing and the phone menu are set up. You’ll review our current Microsoft 365 tenant, adjust Teams policies for groups, and walk me through best-practice configurations.
