I need a seasoned VoIP specialist to take my deployment from zero to fully operational. I will not be supplying configuration files, trunks, numbers, or even the initial account—everything has to be sourced, built, and verified by you. The finished system must speak SIP end-to-end so that soft-phones, desk phones, or mobile clients can register and place calls immediately after hand-over. I expect you to: • Create or configure the account, secure it, and document all access credentials. • Provision at least one SIP trunk or equivalent solution so the platform can dial in and out of the public network. • Set up a clean dial plan with working inbound and outbound routes and test calls in both directions. • Provide two sample SIP extensions (one desktop, on...

Our infrastructure is ready for a major uplift: I am replacing a flat WatchGuard/Ubiquiti environment with a full Cisco Meraki hub-and-spoke SD-WAN. The topology is straightforward—one headquarters that will act as the primary hub, a DR site that will serve as a secondary hub, and four branch offices that will connect as spokes. Here is what I need from you: • Design a Meraki architecture that introduces proper VLAN segmentation, Auto-VPN, traffic shaping, and advanced security while mapping cleanly to the existing IP ranges. • Produce a configuration set for MX security appliances, MS access/distribution switches, and any required SFP or PoE considerations so the cut-over is as close to “plug and play” as possible. • Create and document a migrati...

I’m facing recurring connectivity and performance issues across my small-office network and need a technician who focuses specifically on network support to step in quickly. The job is entirely remote: you’ll connect to my environment, pinpoint the root cause of dropped connections and sluggish speeds, and then apply a clean, documented fix. Here’s what I expect: • A thorough diagnostic session covering routers, switches, and current cabling layout (where traceable from afar). • Implementation of configuration changes or firmware updates that restore stable throughput. • A concise report outlining the problem, the steps you took, and any preventive recommendations. Experience with common SMB hardware (Cisco, Ubiquiti, MikroTik, or similar) and standa...

NS-3 Network Simulation Task Project Overview I am looking for assistance with a small networking task using NS-3 which can be downloaded via: (ns-allinone-3.35 version). The goal of this task is to work with the provided simulation example and modify it to evaluate network performance metrics. The task focuses on understanding how NS-3 can be used for analyzing communication networks that include both wired and wireless connections. Required Tasks The selected freelancer should: • Modify the source file in NS-3. • Calculate and display the following performance metrics at the end of the simulation: o End-to-end delay o Throughput • Update the client node behavior so it sends more than one packet during the simulation. • Use the MakeCallback() function within th...

Our organisation runs a geographically-distributed Wide Area Network and I want independent confirmation that the data moving across it cannot be intercepted, decoded, or manipulated. The engagement is limited to traffic analysis and sniffing on the live WAN links; firewall rule-sets and router configurations are out of scope unless you discover something during capture that clearly ties back to them. Scope • Perform lawful, ethical interception of packet flows on agreed WAN segments. • Analyse captured traffic for clear-text credentials, session fixation, protocol misconfiguration, or other weaknesses that could lead to privilege escalation or data leakage. • Attempt non-disruptive proof-of-concept exploits only where traffic analysis indicates a realistic attack pat...

I am standing up a full, multi-tenant Network Operations Center that must handle both L1 monitoring and L2 operational tasks for our managed-service customers. From day one the stack has to scale, isolate tenants cleanly, and integrate into our existing ITSM workflow. Monitoring & Dashboards • Monitoring platform: Zabbix is the preferred core. • Dashboards: must surface real-time data for each tenant with role-based visibility, SLA counters, and clean hand-off to ticketing. • Advanced alerting comes in during Phase 2, tied to Cisco ecosystem metrics. Log Management Centralized logging plus log correlation and analysis are required so we can move straight from an alert to actionable insight without hopping between tools. Phased Build Phase 0 (2-3 w...
