Take your work extension anywhere — HD calls, visual voicemail with transcripts, team messaging, and instant alerts on your organization's ACS phone system.
AustenTel ACS puts your organization's phone system in your pocket. Make and receive calls with your work extension, check voicemail with automatic transcription, message teammates, and stay reachable wherever work takes you.
ACS is the AustenTel Advanced Communication System — a carrier-grade, cloud-hosted business phone platform. The ACS app connects to your organization's ACS service, so your business extension rings your iPhone like a native call.

GETTING STARTED
The ACS app is for organizations using AustenTel ACS phone service. Your administrator provisions your extension and sends you a setup code or QR — enter or scan it and you're connected. There is no self-serve account setup.

The ACS app requires an active AustenTel ACS extension.

• All-new calling engine — your work extension rings like a native call, even when the app is closed
• Visual voicemail with automatic transcription
• Team messaging with photo sharing
• Company directory with live presence
• Organization-wide instant alerts (where enabled by your admin)
• Modern security throughout (TLS + SRTP)
After updating, sign in once with the setup code from your administrator.
