Ring groups and call queues route incoming calls to multiple potential answerers — essential for teams handling shared call volume. This guide covers configuring both in FreePBX.
Ring Groups vs Call Queues: The Key Difference
See How to Install FreePBX on a VPS for base setup — ring groups simultaneously or sequentially ring multiple extensions until someone answers (simpler, no hold/waiting concept); call queues hold callers in an ordered wait line, distributing to available agents as they become free (more sophisticated, appropriate for genuine call center-style volume).
Setting Up a Basic Ring Group
In FreePBX admin: Applications > Ring Groups > Add Ring Group — define the extension list and ring strategy (ring all simultaneously, or sequentially hunt through the list).
Choosing a Ring Strategy
| Strategy | Behavior |
|---|---|
| Ring All | All extensions ring simultaneously; first to answer gets the call |
| Hunt | Rings extensions sequentially in a defined order |
| Memory Hunt | Sequential, but remembers where it left off for next call (round-robin fairness) |
Setting a Ring Group Timeout and Fallback
Configure what happens if no one answers within the ring group's timeout — typically routes to voicemail (see How to Configure Extensions and Voicemail in Asterisk) or an alternative destination, ensuring calls don't simply ring indefinitely with no resolution.
Setting Up a Call Queue for Higher Volume
Applications > Queues > Add Queue — define queue members (agents), strategy for distributing calls, and hold music/announcements for waiting callers.
Choosing a Queue Distribution Strategy
| Strategy | Behavior |
|---|---|
| Ring All | All available agents ring simultaneously for each call |
| Least Recent | Routes to the agent who's gone longest without taking a call (fairness) |
| Fewest Calls | Routes to the agent who's handled the fewest calls (load balancing) |
Configuring Queue Announcements and Hold Music
Set up periodic announcements (estimated wait time, position in queue) and appropriate hold music — genuinely improves caller experience during wait time compared to silence or a generic default.
Setting Up Queue Overflow Handling
Configure what happens if the queue exceeds a maximum size or wait time — typically routes overflow calls to voicemail or an alternative queue, preventing indefinite hold times during genuinely high-volume periods.
Adding Agents to a Queue Dynamically
FreePBX supports both static (permanently assigned) and dynamic (agents log in/out) queue membership — dynamic membership is appropriate for shift-based staffing where agent availability genuinely varies.
Monitoring Queue Performance
See How to Set Up Call Center Features (ACD, Wallboards) for more advanced queue monitoring/reporting — FreePBX provides basic queue statistics (calls answered, abandoned, average wait time) valuable for understanding whether your queue configuration genuinely meets your call volume needs.
Common Errors
Calls ring but agents report never seeing them — verify agent extensions are genuinely correctly configured as queue members, and check for any conflicting Do Not Disturb settings or extension-level call forwarding that might be intercepting calls before they reach the queue distribution logic.
