BlogWhat Is a Hunt Group? A Complete Guide for Businesses

Most small teams do not want callers to guess who is free. They want one number that reaches somebody. A hunt group is the feature that makes that work: a set of users or lines that share a single number, where the system hunts through the group until a member answers. The name comes from old telephone exchanges, which would "hunt" down a list of lines looking for a free one.

The idea has not changed, but the tools have. On a cloud phone system a hunt group takes minutes to build, follows people to whatever device they are on, and can be pointed somewhere sensible when nobody picks up. This guide covers how hunting works, the types you can choose from, where it fits against a call queue or an IVR, and how to set one up without annoying your callers.

What is a hunt group?

A hunt group is a group of phone users that share one number. A caller dials that number, and instead of ringing one desk, the system tries the members of the group according to a rule you set, until one of them answers or the group runs out of people.

Three things define a hunt group: the members in it, the hunting pattern that decides who rings and in what order, and the fallback that catches the call when nobody answers. Get those three right and the feature disappears into the background, which is what you want.

You will also hear hunt list and call group, and often ring group, which is close but not identical; we cover that difference below. In Calilio you build one by setting a Ring Strategy on a number.

How a hunt group works, step by step

From the caller's side nothing unusual happens. They dial a number and someone answers. Behind that, four things take place.

1
A call arrives on the group number
The caller dials one number. They do not need to know who is on shift or who handles what.
2
The system picks who to ring first
That choice comes from the hunting pattern you set. It may be everyone at once, the first person on a list, or whoever is next in the rotation.
3
It hunts on if there is no answer
Each member rings for a set number of seconds. If nobody picks up, the call moves to the next member and keeps going until it reaches the end of the group.
4
The fallback catches what is left
If the whole group misses the call, it goes wherever you decided: voicemail, another number, or an AI voice agent that answers and takes the details.

Types of hunt group

The hunting pattern decides who does the work, so it is the part worth thinking about. Five patterns are in common use. Strictly, the first one is ring-group behaviour rather than hunting, but most systems list it in the same menu, so it belongs here. The first three are found on almost every business phone system; the last two are more common on contact-centre platforms.

≡

Simultaneous hunting
Also called broadcast ring or ring all

Every member's phone rings at the same moment, and the first person to pick up takes the call. It is the quickest way to get a call answered, because nobody waits for a ring cycle to finish.

Good for
Small teams, urgent lines, and anywhere answer speed matters most.
Watch out for
Everyone's phone rings constantly, and the fastest person ends up taking most of the calls.

→

Linear hunting
Also called sequential ringing or a hunt list

The system always starts at the top of the list and works down. Member one rings, then member two if there is no answer, then member three, in the same order every time.

Good for
Teams with a clear first choice: an account owner, a receptionist, or tonight's on-call person.
Watch out for
The person at the top takes nearly everything, and callers wait longer with each extra step.

⟳

Circular hunting
Also called round robin routing

The starting point moves along with each call. Call one starts at member one, call two at member two, and so on, so the group shares the load over the day.

Good for
Sales and support teams of equals, where calls and leads should be split fairly.
Watch out for
Not what you want when one person genuinely should be tried first.

◷

Longest idle
Also called most idle or least recent

The call goes to whoever has been off the phone the longest. Unlike circular hunting, it looks at actual time since the last call rather than a fixed turn order, so someone who has just finished a long call is not immediately rung again.

Good for
Busy support desks where call lengths vary and you want the rest between calls to be fair.
Watch out for
Needs the system to track agent status accurately; less common on simple business phone systems.

✦

Skills-based routing
A contact-centre routing pattern

Each member is tagged with skills such as a language, a product or a seniority level, and the call is matched to a member with the right skills. An IVR menu or the caller's number usually tells the system which skill is needed.

Good for
Larger teams handling different products, languages or tiers on the same number.
Watch out for
More setup and upkeep, and it depends on having enough people with each skill on shift.

Hunt group vs ring group: what's the difference?

Both let a group of people share one phone number, and both aim to get the call answered. The difference is how they ring. A ring group rings every phone in the group at the same time, and the first person to pick up takes the call. A hunt group rings phones one after another, searching for an available person using a pattern such as linear, round robin or longest idle.

The practical difference is control. In a ring group every line rings for every call, so the fastest hand wins and the whole room hears the phone. A hunt group lets you decide who is tried first, how long each person rings, and how calls are shared, which is why it suits teams with a receptionist, an account owner, or an uneven mix of experience.

Why hunt groups are worth setting up

Fewer missed calls
A call has to be missed by everyone in the group before it goes unanswered, rather than by one person at one desk.
One number to publish
You can change who answers, and in what order, without ever changing the number on your website or invoices.
Cover without extra staff
A three-person team can cover a line all day simply by being in the same group.
Work from anywhere
Because members are users rather than desk phones, the group follows people to the web app, the mobile app or a desk phone.
Fairer workload
A circular pattern spreads calls across the team instead of letting them pile onto whoever answers fastest.
Quick to change
Adding someone to a rota, or reordering the chain, is a setting rather than a support ticket.

How to set up a hunt group in Calilio

In Calilio a hunt group is called a Ring Strategy, and it is set per number. It is available on both plans, so there is nothing to buy separately.

1
Go to Settings, then My Numbers
Open Settings from the left sidebar and choose My Numbers. You will see every number on your account, with its current call strategy shown in the list.
2
Select the number
Click the number you want the hunt group to answer, for example your support line. This opens that number's settings page.
3
Open Ring Strategy
Scroll to the Ring Strategy card and click the settings icon. This is where you configure how incoming calls are distributed among team members.
4
Choose the strategy and build the agent pool
Pick Simultaneous Ring, Sequential Ring or Round Robin from the dropdown, then use Add Agent to choose who is in the pool. For sequential, drag agents into the order you want them tried.
5
Set the timeouts and save
Under Timeout Settings, choose the Ring Timeout Per Agent and the Maximum Ring Duration before the call goes to fallback. Click Save. The overview at the top confirms the active strategy, agents in pool and wait times.

Conclusion

A hunt group is one of the simplest things you can add to a business phone line, and one of the few that callers notice immediately, because the phone gets answered. Decide who is in the group, pick the hunting pattern that matches how the team works, keep each ring step short, and give the call somewhere useful to land when nobody picks up. On Calilio the simultaneous, sequential and round robin patterns are set from one Ring Strategy screen per number, on either plan.

Frequently Asked Questions

What is a hunt group?
A hunt group is a set of users or lines that share one phone number. When a call comes in, the system hunts through the group until someone answers. It lets a caller reach your team on a single number without knowing who is available.
Is a hunt group the same as a ring group?
Not quite. Both share one number across a group, but a ring group rings every phone at once and the first to answer takes the call, while a hunt group rings phones one after another using a pattern such as linear, round robin or longest idle. Many cloud systems, Calilio included, offer both behaviours from the same setting.
What is the difference between a hunt group and a call queue?
A hunt group rings members until someone answers, then sends the call to a fallback if nobody does. A call queue holds callers in line with hold music and connects them as agents free up. Hunt groups suit teams where someone is usually available; queues suit high volume where waiting is expected. Calilio offers hunt groups but does not offer call queues.
What are the types of hunt group?
Five patterns are in common use. Simultaneous hunting rings everyone at once. Linear or sequential hunting tries members in a fixed order. Circular or round robin hunting moves the starting point along with each call. Longest idle rings whoever has been free the longest. Skills-based routing matches the call to a member with the right skill. Calilio offers the first three.
What happens if no one in the hunt group answers?
The call goes to whatever fallback you set. In Calilio that can be voicemail, forwarding to another number, or the AI voice agent, which answers the caller, handles the query where it can and records the details for follow-up.
Does a hunt group work with remote teams?
Yes. Members are users rather than physical phones, so the group rings whichever device they are signed in on — the web app, the mobile app or a desk phone. Someone working from home is rung exactly like someone in the office.
Which Calilio plan includes hunt groups?
Both. Ring strategies — simultaneous ring, sequential ringing and round robin routing — are available on the Standard plan at $15/user/month, or $12 billed annually, and on the Premium plan at $35/user/month, or $28 billed annually.
