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...

I need my Zoom Phone account turned into a polished business phone system. The priority is to build a virtual receptionist that can immediately answer calls, play a clear custom greeting I will supply, offer recorded information, and then transfer callers to the right extension or voicemail without human help. Call-forwarding is required as well, but I’m still deciding whether it should be scheduled or always-on, so I’ll rely on your advice and best-practice examples before we lock it in. You will handle every step inside the Zoom admin portal—creating the Auto Receptionist, setting up call queues if needed, uploading the custom greeting, mapping extensions, voicemail, and designing an intuitive call-flow. I’d also like a quick walk-through (live or recorded) ...

We are developing a Push-to-Talk (PTT) communication platform called PTTHEX and are looking for an expert consultant with hands-on experience in 3GPP Mission Critical Services (MCX) standards and certification processes. PTTHEX transforms smartphones into professional push-to-talk devices for sectors such as public safety, construction, logistics, and healthcare. We are exploring the path toward full 3GPP MCPTT compliance and GCF certification, and need expert guidance. We want to start with an initial consultation call to: - Assess our platform against 3GPP MCPTT standards (TS 22.179, TS 23.379, TS 24.379) - Understand the gap between our solution and full GCF/TCCA certification - Get a realistic roadmap and cost estimate for achieving compliance - Discuss interoperability requirements ...

We have a self-hosted 3CX phone system that is already up and working. What I now need is an experienced 3CX administrator who can take over the day-to-day care of the platform so it stays secure, performant, and fully backed up. The core of the engagement is ongoing maintenance: • Regular updates carried out manually, only after I receive a short heads-up summarising what is about to change and any expected impact. • Backup management that keeps encrypted snapshots on my designated off-site storage, with a quick-restore plan tested periodically. • Continuous monitoring of system health, trunks, and call-quality metrics, with monthly reports that highlight trends and any recommended actions. Ideally, we’re looking for someone based in North America and in a simi...

I need experienced field engineers and riggers who can take full ownership of RAN/RF installation and commissioning work across multiple mobile sites. Your core responsibility will be bringing new radio nodes on-air—mounting antennas, running feeders, integrating the cabinets, and turning up carriers—until each site passes acceptance. Installation & Commissioning is the primary focus, so hands-on familiarity with typical OEM toolchains (Site Manager, NetAct, OSS, WebLMT, etc.) and test sets (Anritsu, Keysight, TEMS) will help you hit the ground running. Any vendor, safety, or tower-climbing certification is highly valued—preferable but not mandatory—as long as you can demonstrate real-world competence and follow our HSE guidelines. Beyond the physical build yo...

I recently added a new SIP trunk to my setup—FreePBX 15 sitting behind a Kamailio SBC—but the trunk will not register and no outbound calls complete. I need someone who understands FreePBX 15, Asterisk SIP settings, and Kamailio routing to: • Diagnose why the trunk fails to register with the provider • Configure the correct authentication, codecs, and SIP headers so outbound calls connect cleanly • Provide a brief step-by-step summary of the changes you make so I can replicate them in the future You will have to work via Anydesk, you won't be able to directly connect to our server.

I need a seasoned Radio Access Network expert to stress-test the solution my team is building in three key areas. First, you will comb through 35–45 existing datasets and feature columns drawn from 4G/5G CM, PM, KPI and call-trace sources. Your job is to confirm each field’s value for fault detection, highlight any RAN counters or critical signals we have missed, and flag redundant noise we can drop. Next, you will review the correlation logic that powers our automated root-cause analysis. I will share flow-charts, rule sets and a Bytelens sandbox. I want to know whether the way we link alarms, counters, interference metrics and topology really mirrors what happens on a live network and matches common troubleshooting practice in the field. Finally, you will turn the insights...

I’m starting a 10–15 day pilot for a voice-based helpline aimed at keypad-phone users across India and need support to set up the IVR and refine the call flow based on real user interactions. For this pilot, I will personally handle all incoming calls to understand real user problems and behaviour. Your role will be to translate these insights into a simple, effective IVR system on Exotel — mapping flows, configuring logic, and iterating quickly as patterns emerge. The team will not be handling user calls during this phase. This is an early-stage pilot with a limited budget, and I’m looking for a simple, fixed-scope setup for this phase. Open to discussing a reasonable structure based on scope. We’ll work in short remote syncs, share call inputs, and cont...
