On each Power Mobile subscriber line, you can connect 1 calling application (or SIP PBX), 1 compliance call recorder, and 1 AI voice assistant.

Prerequisites

Make sure your organization has an active Power Mobile subscription, assigned Mobile Numbers, and required permissions.

Connect a calling app or SIP PBX

You can link a Power Mobile line to an approved mobile calling application (such as Microsoft Teams Mobile, Movius, or Zoom Phone) or directly to your company SIP Trunk / PBX:

Open Power Mobile and select the subscriber line you want to configure.
In the User (calling application) section, select your application or SIP Trunk / PBX from the dropdown list.
If your third-party application provider requires custom validation parameters, open Interconnect parameter and enter the Key and Value provided by your vendor.
Select Save.

How calls work when an app or PBX is connected

When a calling app or SIP PBX is connected to a Power Mobile number, the connected app or PBX controls both incoming and outgoing calls:

Incoming calls: Calls to the mobile number are delivered to your connected app or PBX first. Your app or PBX then decides whether to ring the user's app client (on desktop/mobile data) or route the call back to ring the employee's physical SIM/eSIM.
Outgoing calls: Whether the employee dials from the calling app or from their phone's native SIM dialer, the call is routed through your connected app or PBX first so your company's call policies and caller ID rules are applied before the call connects to the destination.
Strict compliance protection: If your connected app or PBX is unreachable after failover, incoming and native-SIM outgoing calls will not bypass the app—ensuring unmonitored calls never slip past your company's routing policies.

Turn on Mobile Call Recording

Power Mobile supports two compliance recording options for regulated industries:

Recording option	How to set it up
B3 Own Recording (Native recording)	Uses your organization's Call Recording subscription (your recording session count must not exceed your Power Mobile Concurrent Session count).
Third-Party SIPREC Recorder (External recorder)	In the Recording section of the subscriber line, select an approved mobile recording app (such as ASC Technologies, Touch Suite, or Verint) from the dropdown list.

Set up recording announcements and periodic beep tones

When call recording is enabled on a mobile line, you can notify callers and recipients automatically:

Play announcement when recording:

Incoming caller announcement: Play an automated message (text-to-speech or uploaded .mp3 file) to the caller when an incoming call arrives.
Outgoing callee announcement: Play an automated whisper/announcement (text-to-speech or uploaded .mp3 file) when the called party answers.

Play periodic beep tone:

Turn on a periodic compliance beep tone during the call and choose the interval (15s, 30s, 45s, or 60s).

Select Save.

Turn on an AI Voice Assistant

To let an AI voice agent screen or answer incoming mobile calls:

In the AI section of the Power Mobile subscriber line, select AgentDuet from the dropdown list.
Select Save.
