Live-monitoring your agents with VICIfast
VICIfast includes live call monitoring so supervisors can silently listen to agent calls, coach via whisper, or barge in and join the conversation directly.
Call monitoring in VICIfast lets a supervisor join an active agent call in one of three modes: silent listening where only the supervisor hears the conversation, Whisper coaching where the supervisor can speak to the agent without the contact hearing, or Barge-in where the supervisor joins the call as a full participant. All three modes work through the same Asterisk ChanSpy channel on your box, and supervisors control them from inside the VICIdial admin panel.
Why monitoring matters for outbound teams
Live monitoring is one of the fastest ways to improve agent performance because feedback arrives while the call is still happening. A supervisor who whispers a correction in the moment is more effective than a post-call debrief several hours later. For new agents handling complex objections or compliance-sensitive calls, the ability to hear coaching in real time shortens the learning curve without putting the contact experience at risk.
Barge mode is useful in a narrower set of situations: a call that is going sideways and needs an experienced voice, or a transfer scenario where the supervisor needs to take over rather than just guide. In both whisper and barge modes the agent knows the supervisor is on the line, which is different from silent listen where the agent has no indication.
The three monitoring modes
stateDiagram-v2
[*] --> Listen : Supervisor selects agent
Listen --> Whisper : Supervisor activates coach mode
Whisper --> Listen : Supervisor mutes again
Whisper --> Barge : Supervisor joins call fully
Barge --> Listen : Supervisor goes silent
Listen --> [*] : Call ends or supervisor disconnects
Barge --> [*] : Call ends or supervisor disconnects- Listen: the supervisor hears both sides of the call. The agent and contact are unaware. This is the default monitoring state.
- Whisper: the supervisor's audio is sent to the agent's channel only. The contact does not hear the supervisor. Used for real-time coaching without breaking the contact's experience.
- Barge: the supervisor joins the call as a normal participant. All three parties hear each other. Used when the supervisor needs to take over or when a three-way resolution is needed.
How it works on the box
VICIfast monitoring uses the Asterisk ChanSpy application running directly on your Single tenant server. The supervisor connects to the channel through a VICIdial Softphone or hardphone, selects an Agent session from the real-time report, and the ChanSpy bridges the supervisor's audio path to the existing call. No external recording service or relay is involved; the audio path stays on your box the entire time.
Because each VICIfast customer runs their own dedicated server, monitoring access is scoped to your installation only. There is no risk of a supervisor on one account accidentally reaching a call on a different customer's box.
Using monitoring alongside recordings
Live monitoring and Call recording are independent features. You can monitor a call that is being recorded, and the recording will include the full call audio but not the supervisor's whisper track because whisper audio is mixed only into the agent's channel. If you barge in, your audio becomes part of the recording because you are now a full call participant.
Finding calls to monitor
Supervisors find active agent calls through the VICIdial real-time report, which lists every agent currently on a call along with the call duration and current Disposition status. From there, selecting an agent and triggering the listen action connects the supervisor to that channel through ChanSpy. Because all agents on a VICIfast box are on the same single server, the supervisor does not need to query across multiple systems or wait for a data sync. The list is live and reflects calls already in progress.
