Enhanced Ring Groups (ERGs): Administrator Guide
Enhanced Ring Groups (ERGs) are advanced alternatives to traditional call queues in UX systems. They offer flexibility, mobile support, and rich reporting—without the complexity of full queue infrastructure.
This guide covers:
What ERGs are
Key settings and configurations
Ring strategies
Real-world examples
Best practices
What Is an Enhanced Ring Group (ERG)?
Think of an ERG as a lightweight queue. It holds incoming callers and distributes calls to available members, just like a queue—but with more flexibility.
Why Use ERGs Instead of Queues?
Ideal for systems where traditional Queues are being deprecated
Supports mobile devices and push notifications
Includes queue-like features: announcements, wrap-up time, caller control
Offers statistics, reports, and customizable experiences
Key ERG Settings & Options
The table below summarizes the most important ERG settings for administrators:
| Setting | What It Controls | Tips / When to Use |
|---|---|---|
| Max Waiting Callers | Max number of callers who can wait in the ERG. Overflow is redirected. | Set based on team size and call volume to avoid long queues. |
| Wake Up Mobile Devices | Sends push notifications to members even if devices are locked or the app is in the background. | Enable for mobile or remote staff; disable for desk-only teams. |
| Replace CallerID | Replaces the caller ID shown to members with ERG label + original number. | Helps agents see where the call is coming from—great for agents in multiple ERGs. |
| Max Wait Seconds / Destination | Limits how long a caller waits before being redirected. | Prevents excessive hold times. Ensure fallback destinations (voicemail, reception, etc.) are configured. |
| Position & Hold Announcements | Plays messages like “You are #3 in line” or “Estimated wait: 5 minutes.” | Calms callers but may discourage them if waits are long. Use wisely. |
| Periodic Announcements | Custom messages like “Thank you for holding…” or “Press 9 to leave voicemail.” | Provide updates and options. Ensure audio files are formatted properly. |
| Static Members Login | When enabled, members must log in/out to receive calls. | Ideal for shift-based teams or part-time on-call staff. |
| Disable Member Enhanced Services | Ignores forwarding and other user-level features for ERG calls. | Use if you want all ERG calls handled uniformly. Caution: may override user expectations. |
| Wrap-Up Time | Delay between ending a call and receiving the next one. | Gives agents time for notes or follow-up tasks. |
| Exit Digit | Allows callers to press a key (e.g., 9) to leave the queue. | Reduces hang-ups and gives callers control. Always announce this option. |
Ring Strategies: How Calls Are Distributed
Different ring strategies suit different team types. Here’s a comparison:
| Strategy | How It Works | Best For | Considerations |
|---|---|---|---|
| Ring All | All available members are rung simultaneously; first to answer gets the call. | Small teams needing fast response. | Not scalable; can cause system load issues in large groups. |
| Linear Ring | Rings members in a fixed order until one answers. | Prioritizing senior/experienced staff. | Early members get more calls; others may rarely receive calls. |
| Least Recent | Sends call to the member who hasn’t answered in the longest time. | Balanced call distribution. | Can cause delays if agents are idle but unavailable. |
| Random | Randomly selects a member for each call. | Equal opportunity across members. | Unpredictable distribution over time. |
| Round-Robin Ordered (RrOrdered) | Remembers where the last call went and rings the next in sequence. | Fair distribution + structured rotation. | Slightly more complex logic; may need tuning. |
Practical ERG Setup Examples
Example 1: Real Estate Sales (30 Members, 2 Shifts)
Requirements:
Only call agents on duty
Support mobile agents
Overflow to secretary
Long waits → Voicemail
Suggested Settings:
Static Members Login: Enabled
Ring Strategy: Linear
Ring busy members?: No
Wake Up Mobile Devices: Yes
Disable Enhanced Services: No
Max Waiting Callers: Adjust to trigger overflow to secretary
Max Wait Seconds: 600 (10 min)
Max Wait Destination: General voicemail
Example 2: Tech Support (20 Members, Day Shift Only)
Requirements:
Off-hours → Voicemail
Experts get priority
Let callers exit
Supervisor alert on abandoned calls
Suggested Setup:
Operation Hours: M–F, 08:00–16:00
Cascading ERGs:
• Level 1: Experts (Ring All, long timeout)
• Level 2: Other agents (Linear)
• Level 3: Email support or overflow queueMax Wait Seconds: Per level, redirect to next
Exit Digit: Enabled
Abandoned Call Alerts: Notify supervisor via email
Best Practices & Recommendations
Balance Load: Set Max Waiting Callers and Max Wait Seconds to match staffing and call traffic.
Use Announcements Sparingly: They help, but can annoy if too frequent.
Support Mobile Staff: Enable Wake-Up only when needed.
Avoid “Ring All” for Large Teams: Use Linear or Round-Robin for better efficiency.
Enable Login for Shifts: Prevents after-hours interruptions.
Always Provide Exit Options: Tell callers how to leave the ERG if needed.
