3CX Business Phone System — Deployed & Managed by Wekos

Wekos deploys, manages, and supports 3CX unified communications for businesses of every size — from a 10-person office replacing an aging phone system to a multi-site enterprise moving away from costly legacy PBX infrastructure. 3CX gives you enterprise-grade VoIP, softphones, video conferencing, call queues, and IVR without per-user licensing fees, and Wekos gives you the expertise to deploy it right and keep it running.

What Is 3CX?

3CX is a software-based IP PBX and unified communications platform built on open SIP standards. It replaces traditional proprietary phone systems with a modern VoIP solution that runs on Windows or Linux — either on-premise on your own hardware, self-hosted in the cloud on AWS, Azure, or Google Cloud, or hosted directly by 3CX. With over 350,000 installations worldwide, 3CX has established itself as a leading business phone system for organizations that want enterprise-grade telephony without enterprise-grade licensing costs or vendor lock-in.

Unlike legacy PBX systems that charge per extension, 3CX licenses by the number of simultaneous calls — meaning your per-user cost drops as your team grows. Wekos handles the full lifecycle: sizing, deployment, SIP trunk procurement, configuration, user training, and ongoing management.

Why Wekos for Your 3CX Deployment

3CX is powerful, but it rewards engineers who understand VoIP, SIP, and network infrastructure. Dial plan design, SIP trunk configuration, codec selection, firewall traversal, and QoS settings all have real consequences on call quality and reliability. A 3CX deployment done right delivers clear calls, reliable failover, and a phone system your team never thinks about because it just works.

Wekos brings networking and infrastructure expertise to every 3CX engagement — we understand the underlying network that the phone system runs on because we often built it. That means we catch QoS misconfigurations, SIP ALG problems, and bandwidth bottlenecks before they become call quality complaints.

3CX Features — What You Get Out of the Box

Every 3CX deployment includes a comprehensive feature set that covers the full range of business communication needs — voice, video, messaging, and contact center capabilities, all managed from a single web-based admin console.

Softphones & Mobile Apps

Web client, Windows desktop app, and iOS/Android mobile apps — your team makes and receives calls on any device, anywhere. No hardware required for remote or hybrid workers.

IVR & Auto Attendant

Multi-level interactive voice response menus route callers to the right department without a live receptionist. Business hours rules, holiday schedules, and custom greetings all configurable through the admin console.

Call Queues & Ring Groups

Distribute inbound calls across teams with configurable queue strategies — round robin, skills-based, or least busy. Real-time wallboards, SLA alerts, and supervisor monitoring included.

Video Conferencing

Built-in video conferencing for up to 250 participants on enterprise plans — no third-party platform required. Accessible via browser link with no client install needed for external participants.

Call Recording & Reporting

On-demand or automatic call recording with secure storage. Comprehensive call reporting covers inbound and outbound activity, queue performance, agent stats, and historical trends.

Microsoft 365 & CRM Integration

Bi-directional sync with Microsoft 365 and Google Workspace for contact lookup and presence. CRM integrations with Salesforce, HubSpot, Zoho, and more for automatic call logging and screen-pop.

Live Chat & WhatsApp

Website live chat, WhatsApp Business, Facebook Messenger, and SMS all managed from the same 3CX interface as voice calls — giving your team a single queue for every inbound customer channel.

SIP Trunks & BYOT

3CX works with any SIP-compliant trunk provider. Bring your own numbers and carrier, or Wekos can source and configure SIP trunks as part of your deployment. No proprietary carrier lock-in.

Security & Encryption

TLS and SRTP encryption for all calls and signaling. Built-in anti-hacking and IP blacklisting. No call data uploaded to third-party servers — your communications stay on your infrastructure.

Deployment Options — On-Premise, Cloud, or Hosted

One of 3CX’s strongest advantages is deployment flexibility. You are not locked into a single hosting model — choose the approach that fits your infrastructure, compliance requirements, and budget, and change it later if your needs evolve.

On-Premise

3CX runs on your own hardware — Windows Server or Linux. Full local control, data stays on your network, ideal for organizations with compliance requirements or existing server infrastructure.

Self-Hosted Cloud

Deploy 3CX on your own VM in AWS, Azure, Google Cloud, or any VPS. You control the instance, the data, and the hosting costs — Wekos handles the 3CX configuration and management.

3CX Hosted

3CX manages the infrastructure and hosting on their own platform. Lowest operational overhead — ideal for businesses that want fully managed hosting without maintaining their own server.

Wekos can deploy and manage all three approaches. We will recommend the right model for your environment, size the concurrent call capacity correctly, and handle the full configuration so you are not guessing at dial plan settings or SIP trunk credentials.

Replacing a Legacy Phone System?

Most businesses we speak to are running a phone system that is too expensive, too rigid, or simply no longer supported — a Mitel, Avaya, NEC, or Cisco CUCM system that made sense a decade ago but does not fit how the business works today. 3CX is the most common replacement platform we deploy. It delivers feature parity with legacy enterprise PBX systems at a fraction of the ongoing cost — no per-extension licensing, no proprietary hardware requirements, and no multi-year contracts that lock you into terms you negotiated before you understood what you actually needed.

Wekos manages the migration from end to end — number porting, existing hardware assessment, cutover planning, and user training — so the transition is seamless for your team.

Replaces Mitel, Avaya, NEC, Cisco CUCM, and other legacy PBX platforms
Number porting — keep your existing phone numbers
Existing SIP phone assessment — compatible hardware can be retained
Cutover planning with minimal disruption to business operations
Per-user cost typically drops significantly vs legacy licensing
No proprietary hardware lock-in after migration

Per SC

Licensed by simultaneous calls — not per user. Your per-user cost drops as your team grows.

How a Wekos 3CX Deployment Works

Every 3CX project follows the same structured process — from scoping through go-live and beyond.

1. Discovery & Scoping

We review your current phone system, call volumes, number of locations, remote work requirements, and any existing SIP trunks or IP phones that can be retained. Deployment model and concurrent call capacity sized from real usage data.

2. Design & Licensing

Dial plan, IVR menus, call queue strategy, and extension architecture all designed and documented before deployment begins. 3CX licensing procured through Wekos and consolidated on your invoice.

3. Deployment & Configuration

3CX server deployed on your chosen platform. SIP trunks configured and tested. IP phones provisioned. IVR, queues, business hours rules, and voicemail all configured. Full cutover coordinated to minimize disruption.

4. Training & Ongoing Support

User and admin training delivered at go-live. Full system documentation handed off. Ongoing managed support available — updates, adds, changes, and troubleshooting handled by Wekos.
