What Is a Ring Group and How Does It Work?
A ring group is a set of extensions that all ring when a single number is called.
Instead of a call going to one person, it goes to a group. Whoever answers first takes it. Everyone else stops ringing. It is one of the most practical features on any business phone system, and one of the most underused.
Ring Group vs Hunt Group — Is There a Difference?
No. Ring group and hunt group mean the same thing.
Older telephony documentation tends to use "hunt group." VoIP providers, including VoIPninjas, tend to use "ring group." You will see both terms in the wild. There is no functional difference between them — they describe the same behaviour: one inbound number, multiple extensions, one call.
How a Ring Group Works
The mechanics are straightforward.
- A caller dials your number.
- Every extension in the ring group rings at the same time.
- The first person to pick up takes the call.
- All other extensions stop ringing immediately.
That is simultaneous ring. It is the default behaviour for most ring groups and the most common setup for small teams.
The alternative is sequential ring. Instead of all extensions ringing at once, the system rings them one after another. It tries extension one first. If there is no answer after a set number of seconds, it moves to extension two. Then extension three.
Both modes use the same concept — a group of extensions associated with a single inbound number — but they behave differently in practice.
Timeout and Overflow
Every ring group needs a fallback. If nobody in the group answers within a set time, the call has to go somewhere. That destination is called the overflow or timeout action.
Common options include:
- Voicemail — the call drops to a group voicemail box or an individual's voicemail
- Another extension — the call is forwarded to a specific person, such as a manager or duty phone
- Another ring group — the call is passed to a second group, useful if you have a primary and backup team
Without a configured overflow, callers hit a dead end. That is worth avoiding.
Why Ring Groups Matter for Small Businesses
A single handset is a single point of failure.
If one person is on a call, busy, away from their desk, or simply does not pick up, the caller gets nothing. Ring groups solve this without any extra effort from the caller. They dial one number. The group handles distribution.
The practical benefits are:
- No missed calls because one person is busy. If extension one is engaged, extensions two and three still ring.
- No single person responsible for answering. The whole team shares the load.
- No need to give out multiple numbers. One number, one group, shared responsibility.
For a small team of two to five people, a ring group is often all you need to make inbound call handling reliable.
Simultaneous Ring vs Sequential Ring — When to Use Each
Simultaneous ring works best when all members of a group can take any call.
A three-person sales team, for example. Any of the three can handle a new enquiry. All three ring at once. The first to answer takes it. Fast pickup time, shared workload, no one person carrying more than their share.
Sequential ring works best when you want calls to chase a single person across multiple devices or locations.
A sole trader, for example, or an individual who works across a desk phone and a mobile. Set up a ring group that rings the desk phone first, then the mobile app, then drops to voicemail. The caller always reaches the same person — or their voicemail — without you having to be at your desk.
Sequential ring is also useful when you want a clear priority order in a team. Ring the senior account manager first. If they do not answer within fifteen seconds, ring the rest of the team.
Timeout and Overflow Rules — Avoiding Dead Ends
Every ring group should have an overflow destination configured before you go live.
Think through what happens at each stage:
- How long should the group ring before giving up? Twenty to thirty seconds is standard for simultaneous ring.
- Where should the call go if nobody answers? Voicemail is the safest default. Make sure the voicemail box has voicemail-to-email enabled so messages do not sit unheard.
- Is voicemail the right final stop, or should the call try another group first? During business hours, falling back to a second group before voicemail gives callers a better chance of reaching someone.
- What happens out of hours? This is usually handled by your auto-attendant or time-of-day routing rather than the ring group itself, but it is worth thinking through end-to-end.
The goal is that no caller hits silence, a ringing tone with no answer, or an error message. Every call should reach a person or a voicemail box.
Ring Groups by Department
Ring groups work especially well when you organise them by department.
A small business might have three ring groups:
- Sales — extensions for everyone who handles new enquiries
- Support — extensions for everyone who handles existing customer queries
- Accounts — extensions for everyone who handles billing and payments
An auto-attendant presents callers with options: press 1 for sales, press 2 for support, press 3 for accounts. The caller reaches the right team. Not whoever happens to pick up first.
This matters more than it might seem. A caller with a billing query does not want to explain their situation to a sales person, get transferred, and explain it again. Getting them to the right ring group first time reduces frustration and handling time.
Ring Groups With the Mobile App
A ring group is only as good as who is in it.
On a traditional phone system, ring groups were limited to desk phones. If a team member was working remotely or on the road, they were outside the group.
On a VoIP system with a mobile app, every member of the ring group can be reachable wherever they are. A remote worker running the mobile app on their phone is in the ring group the same as someone sitting at a desk phone in the office. The system does not care where they are.
This is particularly useful for small teams where everyone wears multiple hats. Sales calls do not miss the person who happens to be working from home that day. Support calls do not go unanswered because the office is quiet.
Ring Group vs Call Queue — Brief Comparison
These two features are often confused. They are not the same.
A ring group rings all extensions simultaneously. The first to answer takes the call. There is no waiting. If nobody answers, the call times out to the overflow destination.
A call queue holds callers in line. They hear hold music or a position announcement. Agents are presented with calls one at a time as they become available.
Ring groups suit small teams with low-to-moderate call volumes. They are simple to configure and work well when team members can take calls alongside other work.
Call queues suit higher-volume inbound operations — contact centres, busy helpdesks — where callers expect to wait and agents are dedicated to handling calls.
For most small businesses, a ring group is the right tool.

Frequently Asked Questions
Can mobile users be included in a ring group?
Yes. VoIPninjas provides a mobile app for iOS and Android. Any user running the app can be added to a ring group the same as a desk phone user. Their location does not matter — as long as they have a data or Wi-Fi connection, they are reachable through the group.
What happens if nobody in the ring group answers?
The call follows your configured overflow rule. Common destinations are a voicemail box (with voicemail-to-email so you are notified immediately), another extension, or a second ring group. Always configure an overflow destination before you go live.
What is the difference between a ring group and a call queue?
A ring group rings all extensions at once. The first to answer takes the call. A call queue holds callers in a waiting line and presents calls to agents one at a time as they become free. Ring groups are simpler and suit small teams with moderate call volumes. Call queues suit high-volume operations where callers are expected to wait.
How many extensions can be in a ring group?
On VoIPninjas, there is no fixed limit on the number of extensions in a ring group. In practice, a group of two to eight extensions covers most small business use cases. If you have a larger team, organising extensions into multiple department-specific groups is usually more effective than one large group.
