NOTE: This guide will first explore how an admin user can use the Stratus web portal to monitor calls. The last section of this guide will review how users can spy on calls through dialing codes.
Scope: The Stratus web portal's Audio Monitoring tool is only available to users with a scope of a Call Center Supervisor or higher.
Basic Users can monitor/shadow calls by dialing codes for spying using their desk phones.
| Feature Code | Action | Example |
|---|---|---|
| 007<extension number | Spy on Extension's Call | Dial 007100 to monitor or shadow extension 100's call. |
| *81 (once 007 has been used) | Allows Spy to speak with Caller | After dialing 007100 to monitor extension 100, dial *81 to speak with the caller. |
| *82 (once 007 had been used) | Allow the Caller to speak to All Parties | After dialing 007100 to monitor extension 100, dial *82 to speak with everyone present in the monitored call. |
| *80 (once 007 had been used) | Go Back to Spying on Call | After dialing 07100 to monitor extension 100, dial *80 to return to silently listening to extension 100's call. |
Use the Audio Monitoring Tool in Stratus
By utilizing the Join Call (Barge), Whisper, and Listen Only features, Call Center Supervisors and Managers are able to monitor and manage the calls of their agents.
Note: Users can also shadow calls using the 007 code. Dialing 007 and a user's extension number on a desk phone will allow a someone to spy on the user's call.
If needed, the 007 code dialed by users can be disabled or restricted to only being used by a specific user or group of users.
Submit a Request to Disable/Restrict the 007 Code
If you would like the 007 code to be adjusted, you would need an authorized Point of Contact (POC) to contact our technical support team by calling (469) 429-2500, emailing support@spectrumvoip.com, or sending in a ticket using our support website:
https://www.spectrumvoip.com/support/.
In your POC's request, the following should be included:
• How the code should be restricted.
– Should 007 be completely disabled, or should there only be specific people that can use the code?
• If only specific people should be able to dial 007, provide a list of those users and their extension numbers.
• The name and contact information of someone that would be best to contact for any questions.
• A good date and time to test and confirm this change.
As a Call Center Supervisor
To monitor a call as a Call Center Supervisor…
- Visit the Call Center page.
- On the Call Center page, use the AGENTS menu to find the agent's extension number and their call.
- Click the Listen in
icon next to the Agent's extension number.✔ You should see a message that states “Monitoring the Call” while the Audio Monitoring tool loads.
After a short delay, an Audio Monitoring box will appear. Use the Join Call and Whisper buttons to interact with the call's participants as needed.
As an Office Manager or Site Manager
To start the connection as any user with an Office Manager or Site Manager…
- On the Home tab, use the ACTIVE CALLS menu to find the active call to listen to.
- Click the Listen in icon
to the right of the call.
✔ After a short delay, an Audio Monitoring box will appear.
Use Audio Monitoring Features
When listening to a call using the Audio Monitoring feature, administrators can use the Join Call or Whisper to buttons to interact with the call.
NOTE: Join Call (Barge) / Listen Only are available on all calls (i.e., on-net to on-net, and on-net to offnet).
Whisper only works for a call by an agent/employee (on-net) connected to a call that is offnet.
Note: Since audio monitoring sessions start in Listen Only by default, only the Join Call and Whisper To buttons will be visible.
After switching to either Barge or Whisper mode, a Listen Only button will appear in the other buttons' place.
Join Call (Barge)
The Join Call (Barge) feature allows a listener to join into the call, rather than just listen (as is the case with Listen Only). Barge allows both parties of the call to hear the user joining the call.
To barge into a call, click the Join Call button on the Audio Monitoring pop-up.
✔ You should now be able to hear and speak to both calling parties.
Whisper
The Whisper feature allows the whisperer to speak only to the agent (on-net user) on a call. The Caller (off-net) is not able to hear the whisperer.
Warning: The whisper option is only available on Calls where one party is an on-net user, and the other party is an off-net user. This can be either an inbound or outbound call.
To whisper to the agent of the call, press the Whisper To button on the Audio Monitor pop-up.
✔ You should now be able to speak to the agent without the caller hearing.
Listen Only
The Listen Only feature allows the listener to hear both sides of a call but not be heard by either of the other parties.
To use Listen Only after using either Join Call or Whisper, click the Listen Only button on the Audio Monitoring pop-up.
✔ Your connection state will be changed to Listen Only and neither of the parties will hear you further.
Spy on Calls by Dialing
Using dialable feature codes, you can monitor an agent's call from your own desk phone. This can be useful for call shadowing and other training exercises.
| Feature Code | Action | Example |
|---|---|---|
| 007<extension number | Spy on Extension's Call | Dial 007100 to monitor or shadow extension 100's call. |
| *81 (once 007 has been used) | Allows Spy to speak with Caller | After dialing 007100 to monitor extension 100, dial *81 to speak with the caller. |
| *82 (once 007 had been used) | Allow the Caller to speak to All Parties | After dialing 007100 to monitor extension 100, dial *82 to speak with everyone present in the monitored call. |
| *80 (once 007 had been used) | Go Back to Spying on Call | After dialing 07100 to monitor extension 100, dial *80 to return to silently listening to extension 100's call. |
Reminder: If needed, the 007 code can be disabled or restricted to only being used by a specific user or group of users.
