Complete Telephony
Your office extension in your pocket. Make and receive calls from the web app or mobile on your business number, from anywhere you have internet.
Video Conferencing
Video meetings up to 250 participants, no extra license fees, no 40-minute cutoffs. Good enough that most clients stop paying for Zoom separately.
Live Chat & Messaging
Website live chat that flows into the same inbox as your Facebook Messenger, WhatsApp, and SMS conversations. One queue for your team instead of five tabs.
Contact Center
Omnichannel contact center with call routing, IVR, queue management, and a real-time wallboard. Works for 5 agents or 500.
AI-Powered Analytics
Call summaries, sentiment analysis, and voicemail transcription that actually land in your CRM. Less time writing notes after every call.
CRM Integration
Native integration with Salesforce, HubSpot, Zoho, and Microsoft Dynamics. Click-to-call works both directions, and call logs write back automatically.
Microsoft 365 & Teams
User sync, SSO, calendar and contact integration, and Teams presence. If you're on Enterprise Edition, Teams Direct Routing is supported too.
Security & Encryption
SRTP for voice, HTTPS on the web layer, 3CX Tunnel for app traffic. Qualys rates the infrastructure A+. SIP attack protection is built in, not an afterthought.
Flexible Deployment
Run it on-premise, in your own cloud tenant, or on Hyper-V/VMware/KVM. You keep your existing numbers and pick your SIP trunk provider.
Cut Costs Without Losing Capability
The economics work because you stop paying for three or four tools that do what 3CX does in one. Your phone bill drops, your license sprawl drops, and your team stops switching between apps just to return a customer call.
- Typical telecom savings of 30-50%, sometimes higher with heavy international volume
- Licensing based on simultaneous calls, not per user (this alone saves most companies a lot)
- Internal calls between staff, branches, and remote workers cost nothing
- Web-based calling replaces most of your 800 number volume
- Video, chat, and contact center are included at no extra cost
Work from Anywhere
Your extension follows you. Android, iOS, Windows, or just the browser — it's the same interface with the same inbox for calls, chats, and messages. Works well for hybrid teams, sales teams in the field, and anyone who isn't glued to a desk.
- Use your office number on Android and iOS
- Built-in video conferencing from mobile
- WhatsApp and Facebook messaging integration
- Apple CarPlay and Android Auto support
- End-to-end encryption for calls and messages

How does EFROS support 3CX deployment?
We handle the whole lifecycle. That starts with an architecture call to figure out whether on-premise or cloud makes more sense for you, then SIP trunk selection, CRM integration, user training, and ongoing 24/7 support. The goal is that your team shows up Monday morning and the phones just work.

Yes. Native integrations exist for Teams, Microsoft 365, Salesforce, HubSpot, Zoho, Dynamics, and Freshdesk. For phones, 3CX works with any SIP-compatible handset. You keep your numbers through LNP, and you pick your own SIP trunk provider if you have a preference.
