Mobile and Remote Working

Your team doesn't stay in one place anymore

The traditional office where everyone sits at a desk and uses a desk phone is gone. Modern teams are distributed: some work from home. some are on client sites. some travel. A phone system that locks people to a desk is obsolete. Your team needs to make and receive calls from wherever they are. using their business number. without needing multiple phones or special hardware.

The 3CX mobile app

Your staff download the 3CX app on their personal iPhone or Android phone. Log in once with their 3CX credentials. and they're connected. When they get a call on their business number. their phone rings whether they're at the office. at home. or across town. They tap to answer. the call connects. and they're talking to the customer just like they would at their desk phone.

Calls are routed through the 3CX server so the quality and reliability are the same whether you're on mobile or at a desk phone. The 3CX infrastructure handles all the complexity of connecting calls across networks.

WiFi and cellular networks

The app works on WiFi (when connected to a WiFi network) or on the cellular data connection from Safaricom. Airtel. Zuku. or any mobile network. Call quality is optimised to work well over modest connection speeds. so even on 3G you can make and receive calls reliably.

The app switches networks intelligently. If you start a call on WiFi and walk out of range. the call seamlessly switches to cellular without dropping. Similarly. if you get better WiFi signal. the app uses that. All automatic. no manual switching.

Presence and availability

Your staff can set their status in the app: available. in a meeting. on break. away. Colleagues and supervisors see that status. If someone is marked away. calls to them go to voicemail or to a colleague instead of ringing unanswered. This matters for customer experience. Calls don't waste time trying to reach someone who isn't available.

Presence integrates with your calendar. If someone has a meeting on their calendar during a time when a call comes in. the system might automatically route the call elsewhere rather than interrupting them mid-meeting.

Device handoff

Your employee has multiple devices: a desk phone in the office. a laptop with softphone installed. a personal mobile phone with the 3CX app. A call comes in. They can answer on any device. If they're at their desk. they answer the desk phone. If they step out and the mobile app rings. they answer there. The call experience is seamless across devices because it's all the same extension talking to the same 3CX system.

You can also start a call on one device and hand it off to another without dropping. Start a call on mobile while driving. get back to the office. answer on the desk phone and continue without the customer noticing the switch.

Remote work security

Using your business number on your personal phone raises a security question: is that secure? The 3CX app encrypts calls end-to-end. credentials are never stored on the phone in plain text. and 3CX can be remotely managed to enforce policies like device lockdown or app uninstall if a phone is lost or an employee leaves.

For organisations with strict security requirements. you can deploy the app in a containerised or managed mobile device environment. For most organisations. standard deployment with password policies and mobile device management is sufficient.

No extra hardware or SIM cards

A common alternative to VoIP apps is to issue staff a company phone or a secondary SIM card. That adds hardware cost. management overhead. and complexity (now you're managing multiple phone numbers per person). With 3CX mobile. everyone uses their personal phone and the existing data plan. The app uses minimal data (voice calls are very efficient). and you don't add any hardware or carrier costs.
