3CX phone system –
one platform for everything

Phone, video, live chat and WhatsApp in one system – up to 80% cheaper than classic PBXs. PROXYTEC plans, installs and supports your 3CX. And below you will find what is not cleanly documented anywhere else: the complete firewall port list.

One system instead of four isolated tools

In many companies the phone system, video conferencing tool, website chat and messenger run side by side – with four subscriptions and four interfaces. 3CX bundles everything into one platform.

3CX phone system: web client, smartphone apps and a Snom desk phone

Desk phone, web client and app – one extension

Your number rings wherever you are: on a Snom or Yealink desk phone, in the browser or on your smartphone. Calls hand over seamlessly between devices.

  • Presence: see who is free, busy or away
  • Chat, calls and video conferences from the same interface
  • Start calls with one click from your CRM or browser

The office in your pocket

The 3CX apps for iOS and Android turn the smartphone into a fully-fledged extension – with your company’s landline number. Customers see the office number, never the private mobile number.

  • Push notifications wake the app only on incoming calls – sparing the battery
  • Hold, transfer, conference and recording just like at the desk phone
  • Home office without VPN: the app connects encrypted through the 3CX tunnel
3CX admin console: creating the AI receptionist (AI agent)

The AI receptionist answers for you

The AI agent built into 3CX answers calls, recognises the request and connects to the right person – even after hours. Spam calls are filtered out before a human is disturbed.

  • Natural language instead of „press 1“
  • The request is recorded in a structured way and passed on
  • On request with a connection to your ticket system – as in our success story

Administration at a glance

System status, trunks, extensions and blacklist on one dashboard. In everyday terms: new staff are set up in two minutes, and the phone provisions itself.

  • Automatic backups and updates through the interface
  • Call logs, reports and recordings in one place
  • On request we run the whole system as a managed service

Omnichannel communication

Live chat on your website, WhatsApp, Facebook Messenger and SMS all arrive centrally in 3CX – answered by the same team that takes the calls.

Video conferencing included

Web conferences straight from 3CX, no extra licence: participants click a link and join in the browser – nothing to install.

Answered briefly

What does a 3CX phone system cost?

That depends on the number of users and the hosting variant – but thanks to VoIP and low-cost SIP tariffs, running costs are up to 80% below a classic PBX. We prepare a concrete quote for you including a tariff comparison.

How long does introducing a 3CX system take?

A typical installation including number porting is live within a few days. The exact schedule is usually set by the porting deadlines of your current provider – we handle the process.

What happens to our existing phone numbers?

They are ported – with no downtime. Your customers keep reaching you on the familiar numbers; nobody notices the switch.

Do we need new phones?

Not necessarily. Many SIP phones (Snom, Yealink, Fanvil) can be kept; 3CX provisions them automatically. And if you prefer, you can call entirely without a desk phone – via app or browser.
