What is TrueVoIP Extend?
One business number.
Any phone. Anywhere.
TrueVoIP Extend adds a dedicated business SIM to any employee’s phone — BYOD or company-issued. Calls, texts, and voicemail flow through the TrueVoIP platform exactly like any other extension on your system.
There’s nothing to install. Employees use their phone’s native dialer. Business and personal communications stay completely separate, while you retain full visibility and control over every business interaction.
Works with both eSIM and physical SIM cards, so you’re not limited by device type or carrier. Provision a new user in minutes, anywhere in the world.

Why TrueVoIP Extend?
Everything your team needs. Nothing they don’t.
Built for how work actually happens today — mobile, distributed, and always on.
100% Native Experience
Calls use the phone’s native dialer — no app to open, no softphone to load. Employees make and receive business calls exactly the way they call anyone else. Zero learning curve. Zero support tickets.
Business and Personal, Completely Separate
BYOD employees keep their personal number and communications fully private. Business calls, texts, and data travel on the TrueVoIP SIM — visible to your organization, invisible to personal contacts.
Full TrueVoIP Feature Set, On Mobile
Hold, transfer, conference, 4-digit extension dialing, unified voicemail, and presence — all natively available from the phone your employees already carry. No desk phone needed.
Compliance-Ready, Out of the Box
Every business call and text routes through the TrueVoIP platform — just like any other extension on your system. The same recording, monitoring, and reporting you already rely on is automatically extended to mobile, with no additional configuration.
Getting Started
Up and running in three steps.
Provisioning a user takes minutes, not days. No IT headaches. No site visits.
