Phoner

Call routing software with hunt groups, ring groups, and round robin rules

Call routing software decides whose phone rings when your business number gets a call, instead of sending every caller to one device and one voicemail. The common strategies are simultaneous ringing (everybody rings, first to answer wins), sequential or hunt group ringing (phones ring one at a time down a list), and round robin (each new call starts with the next person in the group), usually combined with business hours rules and a failover destination. Phoner includes team call routing and ring groups on the Team plan at $29 per user per month, month to month, with the phone menu, shared numbers, and call recording on the same tier.

Every page in this category lists the same five routing strategies. Almost none of them answer the question that actually decides which one you need: what happens to the second person who calls while the first call is still going on. A ring group has no waiting room. It rings phones, and if the people attached to those phones are already talking, the caller hears ringing nobody can answer. This page prices routing across vendors, then works through the concurrency math that tells you when ring groups stop being enough.

RT-01 Routing Why teams buy it

What call routing does that call forwarding cannot

01

It treats the team as a system, not a destination

Forwarding has one destination: calls to one number ring at one other phone, and if that phone is busy the call dies in that phone's personal voicemail. Routing has a decision tree. It knows who is on the clock, who is already on a call, which group the caller asked for, and where the call should go when nobody picks up. That difference is why a two-person business with routing answers more calls than a five-person business without it.

02

Rules you can read out loud

Weekdays 8 to 6 rings the floor. Saturday rings the on-call phone. Anything after 9pm goes to a mailbox with a greeting that says when you reopen. Each line and each menu branch carries its own schedule, and holiday rules can be set months ahead instead of on the morning of the holiday, which is when everybody remembers them.

03

Failover that ends somewhere useful

If nobody answers within the timeout, the call moves: a backup group, an outside cell number, or voicemail transcribed to text. The worst case becomes a readable transcript in an inbox about thirty seconds after the caller hangs up, rather than a message somebody plays back that evening or a missed call with no context at all.

04

Personal numbers stay personal

A ring group can include mobile numbers alongside the apps, so a call to the published business number rings a teammate's cell without the caller ever learning that number. When somebody leaves, you remove them from a group instead of chasing down which customers have their cell.

How-to Setup

How to set up call routing for a small business team

01

Write down who should answer what, before you touch any settings

Most unhappy phone systems were configured by somebody clicking through a wizard on day one. Spend ten minutes first: list the kinds of call you get, who can genuinely handle each kind, and what should happen at 7pm. If a call type has exactly one competent owner you want sequential ringing. If any of three people could handle it you want simultaneous or round robin. That decision drives everything else.

02

Build the groups before the menu

A phone menu is only a set of signposts, and signposts pointing nowhere are worse than no menu at all. Create the ring groups first (sales, service, billing, or just everybody), pick simultaneous or in-order ringing per group, and set a no-answer timeout of about twenty seconds. Then point the menu branches at groups that already exist and already ring somebody.

03

Set the hours and the failover on every group

Give each group a schedule and a fallback destination: another group, an outside number, or a transcribed mailbox. The failover is the part people skip, and it is the part that decides what a caller experiences on the worst day of your month. Every route should end somewhere deliberate.

04

Test-call it from a phone that is not in the system

Call your own published number from a cell that is not part of any group, at three different times: mid-morning, lunch, and after hours. Watch which phones ring and how long the caller waits. Then have somebody stay on a call while you dial in again, because that is the scenario the settings screen never shows you and the one your busiest hour is made of.

On the record The numbers

Three things about routed phone systems that are law rather than opinion

US businesses running a multi-line phone system have obligations that most buying guides skip entirely. All three below come from primary sources rather than vendor blogs, and the second one is written for exactly the case routing creates.

No 9 first

Kari's Law requires that anyone on a multi-line telephone system can dial 911 directly, without first dialing 9 or any other access code, and that the system notify a central location at the facility when a 911 call is placed. That notification has to carry three things: confirmation a call was made, a valid callback number, and the caller's location where technically feasible. The rules apply to systems manufactured, imported, sold, leased, or installed after February 16, 2020, with a compliance date of February 17, 2020.

Source: FCC, Multi-Line Telephone Systems 911 Requirements

Dispatchable location

Section 506 of the RAY BAUM'S Act requires a dispatchable location to travel with a 911 call: the validated street address of the caller plus the suite, floor, or apartment needed to actually find them. Fixed on-premises devices had to comply by January 6, 2021, and non-fixed on-premises and off-premises devices by January 6, 2022. That second date is the one routing buyers need, because a call routed to a laptop or a cell in another city is precisely the off-premises case the rule was written for. Register an address per user, not per company.

Source: FCC, Multi-Line Telephone Systems 911 Requirements

91%

The share of US adults who own a smartphone, with 98% owning a cellphone of some kind, surveyed February 5 to June 18, 2025. This is the quiet reason routing replaced hardware. The endpoint you are ringing is already in nearly every employee's pocket, so adding somebody to a ring group is a software change rather than a desk, a handset, and a cable run.

Compare The honest comparison

The cheapest plan at each vendor that can ring more than one person

This is the comparison worth making, and it is not the one the pricing pages invite. The advertised entry price in this category frequently belongs to a plan that cannot route a call to a team at all, so the number you budgeted and the number you end up paying are one tier apart. Every figure below was read from the vendor's own published pages, and where a vendor does not state which plan carries the feature, this table says so instead of guessing.

Vendor Cheapest plan that rings a team Price What the vendor calls it Where this came from
Phoner Team $29 per user per month, month to month, no seat minimum Team call routing and ring groups Our own pricing page. The phone menu, shared numbers, texting, and recording sit on the same tier.
Google Voice Standard $20 per user per month, plus a Google Workspace subscription per user billed separately Ring groups Google Voice plans and features, read August 2026. Starter at $10 has no ring groups and no auto attendant, so the advertised price doubles the moment a second person needs to answer.
Quo (formerly OpenPhone) Business $23 per user per month billed yearly, $33 billed monthly Custom ring groups Quo's own call routing page, read August 20, 2026. Starter carries business hours, basic forwarding, and shared number routing, but ring groups and phone menus are on Business.
Nextiva Not published Entry plan is $15 per user per month billed yearly Hunt group Nextiva names and documents the feature but its hunt group page does not state which plan carries it (read August 20, 2026). Ask before you buy.
RingCentral Not published on its routing page Core is $20 per user per month billed yearly, $30 billed monthly Call queues RingCentral's call routing page does not state tier placement (read August 20, 2026). Its plan comparison is a JavaScript calculator rather than a table, which is part of the problem.
Grasshopper Not published either way Plans are $14 to $55 per account billed yearly, flat rather than per user Not published Grasshopper publishes a phone menu and a call recording product. It does not publish ring group availability, so we do not assert that it has them or that it lacks them.

Swipe sideways for the full table

Three of the six vendors here do not publish which plan carries the feature that lets a second person answer the phone. That is the most consequential unknown in a routing purchase, and it is unknowable from the pricing page. Ask in writing and make sure the plan name appears in the answer, because "yes we support hunt groups" and "yes, on the plan you are looking at" are different sentences.

Breakdown Line by line

The five ringing strategies, and what each one does to the second caller

Almost every routing decision comes down to this table. The strategies are not better or worse than one another, they are bets about what you value: speed of answer, even workload, or predictable escalation. The third column is the one other comparisons leave out, and it is usually the column that decides whether a setup survives your busiest hour.

Strategy What actually happens What the second caller gets Best for The trade-off
Simultaneous ringing Every phone in the group rings at once and the first person to answer takes the call Rings on any phone still free. If all of them are busy, ringing that nobody can answer, then failover New leads and sales lines, where speed of answer decides whether you win the business Everybody is interrupted on every call, so people start ignoring the ring
Sequential, in a fixed order (a hunt group) Rings person one, then person two, then person three, on a timeout each Hunts down the same list and skips whoever is already talking, so it reaches the list faster and runs out sooner Escalation paths where a specific person should get first refusal Slowest to answer, and the caller hears a lot of ringing before anyone picks up
Round robin Starts each new call with the next person in the group, moving through in order Starts at the next person along, which is exactly the point: load stays even instead of landing on the fastest picker-up Support desks where even workload matters more than raw speed A caller can wait through several ring cycles at a quiet moment
Longest idle Rings whoever has gone longest without taking a call Goes to the next longest idle person, so a busy desk self-levels without anybody managing it Busy desks where you want to balance genuine talk time rather than call count Only works if presence and status are accurate, which takes habit. Phoner does not offer this one.
Overflow to a second group The first group tries, then the call moves to a backup group or an outside number Reaches the backup group sooner, which is the whole reason to have one Peak hours, lunch cover, and after-hours on-call rotations It quietly hides understaffing unless somebody reads the reports

Swipe sideways for the full table

Read the third column twice. None of these strategies hold a caller in a queue: they ring phones. If two callers regularly arrive while your team is already talking, you have a concurrency problem that no ringing strategy solves, and the fix is either more people on the group or a system with a real hold queue.

Straight talk The limits

Where this kind of routing stops, and what you should buy instead

Four honest limits. If your situation is described below, a small business phone system is the wrong purchase and you will be happier spending more somewhere else.

There is no hold queue, and that is a real ceiling

Phoner routes calls to people and groups. It does not queue callers with hold music, position announcements, and estimated wait times the way a contact center platform does. The arithmetic is simple and worth doing before you buy: three people who each spend five minutes on a call can hold three conversations at once, and the fourth caller in that window hears ringing that nobody is able to answer. If that describes a normal Tuesday, you need a system with a real ACD queue, and RingCentral, Nextiva, or a dedicated contact center product will serve you better than we will.

No skills-based or longest-idle routing

Skills-based routing matches a caller to an agent by expertise, language, or product knowledge, and longest-idle routing balances genuine talk time rather than call count. Both are contact center features and neither is something Phoner offers. What we do offer is simultaneous, in-order, and round robin ringing per group, with business hours and failover rules. For a team of two to twenty that is usually the whole requirement, but if you are buying on a routing feature matrix you should know where the list ends.

No workforce management, no service level reporting

You get call analytics on the Team plan: volume, missed calls, who answered what. You do not get agent adherence, forecast-and-schedule tooling, or reporting measured against a service level agreement. Support floors that are managed against an answer-in-20-seconds target need that tooling, and buying a phone system instead is a false economy.

Routing rings whoever the rules say, which includes people in other states

A ring group can reach a cell phone anywhere, and that is the point of it. It also means the phone that rings may be nowhere near the address registered for 911 on that user's account. Routing does not move a registered emergency location. Register an address for each user, keep it current when people move, and treat that as part of setting up a group rather than an afterthought.

On the Line Who it is for

Who buys routing first, and the rule they start with

Small business

The most common starting point in the category: one published number, two to ten people, and a menu that sorts callers before anything rings. Start with a single group that rings everybody, then split it once you can name what the split is for.

Small business phone system

Contractors

Crews are in trucks and on roofs, so the first rule that matters is simultaneous ringing with a cell in the group. The second is a failover to voicemail transcribed to text, because a job site cannot take a message.

Contractor phone system

Law firms

Intake calls are the ones you cannot miss and the ones that come at bad times. Firms usually run intake on a simultaneous group and everything else in order, so a new matter never waits behind a scheduling question.

Law firm phone system

Property management

The clearest case for hours-based rules anywhere in this list. Leasing calls ring the office during the day, and maintenance calls ring whoever is on call tonight, which is a different person every week.

Property management phone system

Real estate

Sign calls are the highest-intent and shortest-lived leads in the business. Ringing several agents at once beats a polished voicemail greeting every single time, because the caller is standing in front of the house right now.

Real estate phone system

Remote teams

Routing is the entire phone system when nobody shares a building. The same group reaches a laptop in one time zone and a cell in another, and the caller cannot tell the difference.

Remote team phone system
In practice How it fits together

Menus, groups, and forwarding: which piece you actually need

Routing pairs naturally with an IVR phone menu: the menu asks, routing delivers. Sales branch to the sales group, service to service, and every unanswered leg lands in voicemail to text so the message gets read rather than archived unheard. Teams that are unsure which of the two they need should start with the menu, because a phone menu for small business answers instantly and sorts the caller even before any group exists. If you are coming from a plain redirect on a carrier line, the business call forwarding service page compares the two approaches honestly, star codes included.

The vocabulary in this category is a mess and it costs buyers money, because two vendors will quote you different products under the same word. Some manufacturers use hunt group to mean strictly sequential ringing and ring group to mean simultaneous, while others use the two interchangeably for the same feature. A call queue is a genuinely different thing: it holds callers in a waiting line rather than ringing phones. Before you compare two quotes, get each vendor to describe what happens to caller number two, in a sentence, and you will find out quickly which product you were actually being sold. Our breakdown of what a ring group is walks through the same distinction with the sizing arithmetic, and forwarding business calls to a cell phone covers what routing does that carrier call forwarding cannot.

Price the tier, not the product. In this category the feature that lets a second person answer the phone is almost never on the plan in the advertisement, so the honest way to compare two vendors is to find the cheapest plan at each that can ring a team and set those two numbers beside each other. That is what the table above does. If you want the same treatment applied to everything else a phone system costs, the business phone system cost page prices the whole bill including the parts that are metered, and the business phone system comparison sets the major vendors side by side on the terms that actually differ.

FAQ Questions people ask

Call routing: the questions buyers actually search

Call routing is the set of rules that decides which phones ring when someone calls your business number, and what happens if nobody answers. Instead of one number reaching one device, routing can ring a group of people at once, ring them one at a time in order, follow business hours, and send unanswered calls to a backup group, an outside number, or voicemail transcribed to text.

A call arrives at your business number and the system checks its rules in order: what time it is, which menu option the caller chose, and which people in the target group are available. It then rings the phones that match, waits out a no-answer timeout of around twenty seconds, and moves the call to the failover destination if nobody picks up. All of this happens in the provider's software, so no hardware is involved.

A hunt group routes a call from one number to a group of people by hunting down a list of extensions. If the first person does not answer within a set time, the call moves to the next, and it keeps going until somebody answers or the list runs out. Some vendors use hunt group to mean strictly sequential ringing and ring group to mean simultaneous ringing, while others use the two terms for the same feature.

In the strictest usage, a hunt group rings phones one at a time down a list and a ring group rings them all at once. In practice the two terms are used interchangeably by many vendors, and the same feature gets both names. Rather than argue the vocabulary, ask which ringing strategies a product supports, because simultaneous, sequential, and round robin are the things you are really choosing between.

Forwarding is a single redirect: calls to one number ring at one other number, and if that phone is busy the call ends in that phone's voicemail. Routing treats the whole team as a system, with rules about who rings, in what order, during which hours, and where a call goes when nobody picks up. Forwarding has one destination. Routing has a decision tree.

Round robin starts each new call with a different person, moving through the group in order so the same teammate is not always first. It spreads load evenly across a support desk and stops the fastest picker-up from absorbing every call. The trade-off against simultaneous ringing is speed, because the caller may wait through one ring cycle per person before somebody answers.

Simultaneous wins when the caller matters most, like new leads, because the first person free takes the call. In-order or round robin ringing wins for support desks where you want even load and fewer interruptions. Many teams run both, choosing per line: the sales number rings everybody and the service number goes round the group in turn.

Skills-based routing matches each caller to a person based on expertise, language, or product knowledge, so the call reaches somebody who can resolve it on the first attempt. It is a contact center feature that depends on tagging every agent with skills and keeping those tags current. Phoner does not offer it. For teams under about twenty people, a phone menu that asks the caller what they need usually achieves the same outcome with far less administration.

You choose the failover: another ring group, an outside number, or voicemail. With voicemail to text, an unanswered call becomes a readable transcript about thirty seconds after the caller hangs up, so it gets handled rather than lost. The failover is the setting most people skip and the one that decides what a caller experiences on your worst day.

Yes, and it is the rule most worth setting up first. Each line carries its own schedule, so weekdays 8 to 6 can ring the main group, Saturday can ring an on-call phone, and anything overnight can go to a mailbox with a greeting that says when you reopen. Holiday rules can be scheduled months in advance rather than remembered on the morning of.

Yes. A ring group can include mobile numbers alongside the apps, so a call to the published business number rings a teammate's cell and the caller never learns the personal number. Pair it with an emergency address check, because routing a call to a phone in another state does not move the registered 911 location for that user.

Count how often two people call while your team is already on the phone. Routing rings phones, so it works while somebody in the group is free. A queue holds callers in a waiting line with hold music and position announcements, and you need one when callers regularly arrive faster than your team can finish calls. Small teams almost always need routing. Support floors measured against a service level need a queue, and that is a different and more expensive product.

No. Routing rings the apps on iOS, Android, desktop, and web, which is why adding somebody to a group takes about a minute. Standard SIP desk phones are supported if someone in the office insists on real plastic, but most small teams never buy one.
