Benefits
Work from anywhere without missing a beat
The Othos app keeps your team connected and professional whether they're in the office, at home, or on the road.
Keep your business number
Every call you make shows your business number, not your personal mobile. Stay professional from anywhere — clients never see your private number.
Works over WiFi & mobile data
Connect from anywhere you have internet — office WiFi, home broadband, 4G or 5G mobile data. No VPN, no special setup, no IT department needed.
Full call management
Transfer calls to colleagues, put callers on hold, access your extension directory, and manage your voicemail — all the PBX features you'd expect, right on your phone.
Never miss a call
BYOD — use your own device
Same system as your team
App users are full extensions on your Othos PBX — they ring in ring groups, appear in the operator panel, and receive calls routed through your IVR just like desk phone users.

Use Cases
Who uses the Othos mobile app most?
Any team member who isn't always at their desk will benefit — which in most businesses is everyone.
Staff working from home stay connected to the full office phone system. They can receive calls, transfer to colleagues and access voicemail exactly as if they were in the office.
Teams on-site at client premises stay reachable on their business extension. Customers call the office and get transferred through — no one needs to know the technician's mobile number.
For a fully remote business, the mobile app is the entire phone system. Professional business numbers, call routing, voicemail and extensions — no physical office required.
Staff across different locations — Cape Town, Johannesburg, Durban — all share the same phone system and extension directory. Internal calls are free, regardless of location.
Route urgent after-hours calls to an on-call mobile extension through the IVR. The on-call staff member receives calls through the app — no need to share personal numbers.
