Setting up ring groups in 3CX
How ring groups work in 3CX, the ring strategies available, and when to use a ring group instead of a queue.
A ring group is the simplest way in 3CX to make one call ring several people at once. A customer dials sales, three desks light up, whoever is free picks up. No menus, no hold music, no agent log-in. For a small team that just wants calls answered quickly, it is often all you need.
This guide explains how ring groups work in 3CX, the ring strategies on offer, and when you have outgrown a ring group and should move to a call queue.
What a ring group actually does
A ring group is a virtual extension number that points at a list of real extensions. Call the group, and 3CX rings the members by a strategy you set. If nobody answers in time, the call follows a fallback destination you nominate. Think of it as a small team sharing one doorbell. Common uses:
Sales
— ring everyone so the first free person wins the call.
Reception
— a primary person, with a backup who only rings if the first does not answer.
Support
— a handful of staff who all need to hear a call land.
You create ring groups in the 3CX Admin Console. The number you give the group is what you route calls to from an inbound rule or a digital receptionist menu option.
The ring strategies, and what each one is good for
The strategy controls the order and timing of how members ring. Names vary between 3CX versions, but the behaviour is consistent:
Ring all
— every member rings together. Fastest answer, best for small teams who sit near a phone.
Prioritised / hunt order
— ring the first member, then the next, in the sequence you set. Good when one person normally takes the call and others are backup.
Ring all after a delay
— start with one or two people, then widen to the whole group if it keeps ringing.
You also set a ring time — how long the group rings before giving up. Keep it realistic: too long and callers hang up, too brief and nobody reaches a phone.
Setting one up
Labels move around between builds, so here is the shape of the job rather than a click-by-click script:
In the Admin Console, create a new ring group with a number that does not clash with an existing extension.
Add the member extensions, and set the order if your strategy uses one.
Choose the ring strategy and the ring time.
Set the destination if no answer — usually voicemail, a mobile, or a fallback like reception. People forget this step, and it is the difference between a missed call and a lost customer.
Point an inbound rule or IVR option at the group, then test from an outside line.
Each member's own status and business-hours settings still apply, so the group respects who is available.
Ring group or call queue? Knowing when to switch
This is the question that matters most. A ring group is for making the phone ring. A call queue is for managing callers who are waiting. Stay with a ring group when your team is small, calls are answered straight away, and you do not need callers held in line or reporting on wait times. Move up to a call queue when:
- Calls arrive faster than you can answer, and you want callers held in order rather than dumped to voicemail.
- You want hold music, comfort messages or an announced position in line.
- You want agents to log in and out, plus statistics on how the team is performing.
- You need smarter distribution — Round robin, Least talk time or Longest waiting — to share load fairly.
One honest note: call queues and their polling strategies sit in the higher 3CX licence tiers, while basic ring groups are available more broadly. Our guide to 3CX licensing shows what each edition includes.
Common mistakes worth avoiding
No fallback destination.
If the group rings out and goes nowhere, callers get dead air. Always set a no-answer destination.
Too many members on "ring all".
Ten phones ringing for one call is chaos. Group people by role, not floor plan.
Using a ring group as a contact centre.
If you want reports and hold queues, you have outgrown it.
Forgetting after-hours.
A group ringing empty desks at 7pm should hand off to voicemail or an out-of-hours message.

What we see installing this in Melbourne
The mistake we see most often on Melbourne SME sites is a "ring all" group with eight or nine members across sales, accounts and the warehouse. Phones ring on empty desks while the customer waits, and the office sounds like a fire alarm. Trimming the group to the three or four people who actually answer that line, and sending the no-answer leg to a mobile or voicemail-to-email, fixes it in an afternoon.
The other one is upload bandwidth. On a cheap NBN FTTN plan with four or five concurrent calls and a "ring all" group, the early seconds of a call can sound gravelly because every handset is sending signalling at once. We always test ring groups on the actual office connection, not from a laptop on 4G, before we hand over.
Last thing: consumer routers with SIP ALG switched on will mangle ring group behaviour in odd ways. We turn it off as a matter of course during cutover.
Frequently asked questions
What is the difference between a ring group and a call queue in 3CX?
A ring group makes a set of extensions ring and stops once someone answers or the ring time runs out. A call queue holds callers in line, plays hold music, distributes calls to logged-in agents, and gives you reporting. Use a ring group for quick answering in a small team; use a queue when callers must wait and you need statistics.
How many extensions can I put in a ring group?
3CX allows a generous number, but the practical limit is lower. With "ring all", more than a handful of phones ringing at once becomes disruptive. Group by role and keep the list tight.
Can a ring group ring my mobile as well as my desk phone?
Yes. Run the 3CX mobile app on the phone, and that extension can be a group member like any desk handset. You can also send the group's no-answer destination to an external mobile, which is handy for after-hours cover.
What happens if nobody answers the ring group?
The call goes to whatever you set as the no-answer destination — commonly a voicemail box with voicemail-to-email, an after-hours message, or a fallback number. Leave it blank and the caller hears nothing useful, so always configure it.
