3CX Cloud PBX

A modern phone system that fits your budget and your office

Traditional PBX systems are expensive. you buy hardware, install it in a server room, maintain it yourself, and pay for support. it's complicated, requires expertise, and creates an IT dependency. 3CX Cloud PBX removes all of that. the system runs in the cloud, you access it through soft phones on computers and mobiles, and Sentire handles everything.

3CX is a modern, standards-based PBX built for the cloud era. your staff can use desk phones (if you want them), Microsoft Teams, or a mobile app. calls and voicemail sync across devices. the system scales with your business: add a new extension in minutes, no hardware changes needed.

Core features

Extensions and users

each staff member gets a unique extension. they can receive calls on their desk phone, their computer via soft phone, or their mobile via the 3CX app. calls follow them across devices. if someone is on a Teams call and a regular call comes in, they can answer it or forward it. no more being unreachable when you step away from your desk.

Hunt groups and call distribution

if multiple people should answer calls to a main number, a hunt group rings them in sequence or simultaneously. a common setup is a reception team hunt group. calls to the main number ring all reception staff at once, and whoever answers first gets the call. if everyone is busy, the call goes to voicemail or a message saying the office is busy.

IVR (Interactive Voice Response)

an IVR is an automated phone menu. "press 1 for sales, 2 for support". 3CX IVR is simple to set up. you define the menu structure, point each option to the right department, and record prompts. staff in other departments don't hear calls meant for sales. call routing happens automatically.

Voicemail to email

voicemails are transcribed (with varying accuracy) and sent to the recipient's email as both audio and text. you can listen from your email without logging into the phone system. voicemail becomes just another message in your inbox, not a separate system to check.

Call recording and compliance

calls can be recorded for quality assurance or compliance. recordings are stored securely and accessible from the 3CX interface. this is valuable for training, dispute resolution, and regulatory compliance. if a customer disputes what was said on a call, the recording is there.

Devices and clients

staff can use 3CX in multiple ways. a traditional desk phone connected via SIP. a soft phone on their computer (Windows, Mac, or Linux). the mobile app (iOS or Android). Microsoft Teams calling. they can switch between devices seamlessly. a call started on a desk phone can be transferred to a mobile for continuity. all presence information syncs: if someone is on a call, the system shows them as busy.

Scalability and growth

3CX scales from five users to five hundred. adding a new person is as simple as creating a new extension. no hardware changes, no phone line provisioning delays. if you hire ten new people next month, you provision ten new extensions and they're ready. when a person leaves, you remove their extension and reassign their number if needed.

Integration with Microsoft Teams

if your business uses Microsoft Teams, 3CX integrates directly. users can make external calls from Teams using their 3CX extension. presence syncs: if someone is in a Teams meeting, the system knows not to ring them on the phone system. Teams becomes unified communications. for businesses already invested in Microsoft 365, this integration is powerful.
