In Power Trunk, you can add an AI Voice Agent to answer incoming calls or enable Call Recording to capture call audio for quality assurance and compliance.
Prerequisites
Make sure your organization has an active Power Trunk subscription and the required user permissions. To use B3 Own Recording, your organization also needs a B3 Own Recording license on the License page.
Turn on an AI Voice Agent
When you select an AI voice agent (AgentDuet) in the AI section, the AI agent answers incoming calls on your trunk:
-
Standalone AI (when User section =
None): The AI agent answers, handles, and completes the entire call on its own. -
AI with transfer (when User section =
SIP Trunkor3rd-Party App): The AI agent answers incoming calls first and transfers the caller to your PBX or calling app when they need to speak with a person.
Steps
- Open your trunk in Power Trunk and scroll to the AI section.
- Open the dropdown and select AgentDuet.
- Select Save.
- Outgoing calls: Your PBX or calling app can still make normal outgoing calls—outbound calls route directly to the dialed number without passing through the AI agent.
- Separate from Call Recording: Turning on an AI agent does not automatically turn on B3 Own Recording or SIPREC call recording.
Turn on Call Recording
Power Trunk offers two ways to record incoming and outgoing calls:
| Recording option | How it works | How to turn it on |
|---|---|---|
| B3 Own Recording (Native recording) | B3 records the call audio and stores it securely in your portal's Call Recording app. | Assign a B3 Own Recording license on the License page (your recording session count must not exceed your trunk's Concurrent Session count). |
| Third-Party SIPREC Recorder (External recorder) | Streams a real-time copy of the call audio via SIPREC to your external compliance recorder (such as ASC Compliance, Touch Suite, or CPaaS Media Recorder). |
Scroll to the Recording section on your trunk page, open the dropdown, select your recording app, and select Save. |
- Supported combinations: You can use Call Recording together with SIP Trunk, with a Third-Party Application, or with Standalone AI (when the User section is set to None).
- 3-way combination is not supported: You cannot turn on SIP Trunk / Third-Party App + AI + Call Recording all at the same time on the same trunk. See Supported combinations and technical limits for the full compatibility table.
- Removing a recording app: Disconnecting a recording setting on a trunk does not delete your past recordings or cancel your recording subscription.
