Setting up your phone number for optimal success is a key step in getting your users ready for Aircall. While setting up your numbers, you can take a closer look at understanding Aircall routing through this guide.

What is Call Routing?

The Call Routing is the system that dispatches incoming calls, based on the Availability status of users. By understanding and making use of Aircall's routing logic and different ringing rules, you will be able to set each number up to route calls to your Users or Teams based on pre-established criteria such as business hours or skill.

In Aircall, the routing is based on the following distribution criteria:

  • Operational availability

  • Routing principles & logic

  • Ringing rules

Operational Availability

Calls will be routed through to your users based on the business hours of your numbers and the availability of the users assigned to each line. If your phone number is closed, or your users are unavailable, then the call will not be routed to them.

You can follow the set-up guidelines to establish your business hours for each of your phone lines so that the number will open and close automatically each day. Additionally, you’ll want to determine which messages you would like to enable so that customers can either leave a voicemail or call back when the phone number has opened again/there are more available agents.

Next, it’s essential that you have assigned users and/or teams in the call distribution of the phone line so that calls can be answered. As a best practice, we recommend that users utilize the working hour’s feature (set-up through their user profile on the phone) so that their availability will automatically change to Available and Do Not Disturb based on their schedule.

In the Aircall, a user can either be:

  • Available

  • In a call

  • In Wrap-up time or After-call work

  • Set to Do not disturb

  • Offline

These five possibilities are narrowed into three availability statuses which determine how calls are routed:

Available

  • the agent is connected to an app (desktop, web, or mobile)

  • or the user has a Forward-to-device activated

  • the user is not in-call, in wrap-up time, in after-call work (mandatory tagging), outside of their set working hours, or set to Do not disturb

Busy

  • the user is in-call

  • or the user is in wrap-up time or after-call work (mandatory tagging)

Unavailable

  • the user is set as Do not disturb in the availability bar

  • the user is outside of their set working hours

  • the user is offline (the app is switched off, or the computer is in sleep mode/off)

The more users or teams you have assigned to a phone number, the more likely it is that your calls will be answered and you’ll experience fewer missed calls.

Let’s take a look at using that principle to your advantage.

Routing Logic & Principles

As soon as you receive an incoming call with an available user, Aircall will distribute the call to that user, which will ring to their Phone application. This includes all applications they are signed into, as well as any forwarding devices that are enabled on their user profile. The same status is showcased on all of the phones that you are logged into.

Calls are distributed in the order of first in, first out. This means that the older the call, the quicker it will be distributed to the next available user. If a user is a part of multiple teams or assigned to several lines, and is busy when other calls are ringing lines they are assigned to, they will be included back in each distribution as soon as they are available again.

This also includes when a new call comes in and a user was previously engaged in a call, in wrap-up time, or still in mandatory tagging. Aircall will include the user in the distribution once they have become available again, and they will then be able to answer calls that have already been waiting in the queue.

Keep in mind that if teams or users are busy and unavailable to take the call, the call will not be dispatched and will remain in the queue for the allotted queuing time until a previously busy user becomes available again (this also includes users that are offline). However, depending on your settings, there may need to be at least one user currently busy for a call to wait within the queue. By default, if no users are busy, and everyone is either Offline or set to Do not disturb, the call will skip to the next position in the queue.

Depending on the workflow you’ve set up for your number, calls could go to the voicemail or absence message and then will appear as a missed call in the To-do section of the Phone for the users who are assigned to the line.

Ringing Rules for Teams

In Aircall, you’ll have three standard ringing options to choose from when utilizing a Team. If you have assigned one user to a phone number, then the ringing rule will be set to 25 seconds (around five rings). Unfortunately, it is not possible at this time to adjust the ringing time for individual users, which will need to be taken into consideration when you are setting up your phone numbers and specific team queuing times.

Random

Aircall will select a random user within the team that is available as well as wait for any busy user (they will be added back into the distribution if they become available before the end of the team queueing time. The queue time is set to your preference in the Number Settings, but will ring to the user for 25 seconds).

Simultaneous

Aircall will ring to all available users, as well as wait for any busy user to become available again (they will be added back into the distribution if they become available before the end of the team queueing time).

Longest Idle

Aircall will ring for 25 seconds to the user who has been "Idle" for the longest amount of time. Should that user not answer, the call will ring to the user with the next longest idle time.

Note for Mobile App users: Due to the mobile SDK restriction on Android and IOS, we can only ring users for 40 seconds, regardless if the queuing time is set for longer.

If you need help troubleshooting a few scenarios, let’s take a look at a few routing examples:

Synopsis

Result

Example Scenario

If you are in a team, and the ring rule is set to simultaneous and you decline the call...

If a user declines a call by pushing the decline button, the call will not come back to the user ever.

John is an Admin user who is assigned to the first team in the queue of Hotline Support. He is also assigned to the backup emergency team assigned in the second position.
Because John was assisting a fellow team member when an incoming call rang to his phone, he declined it.

However, the call is still waiting in the queue, and although John has become available again, the call is now passing to the second team.
Because John declined the call, it will never ring to him again. However, he'll be able to receive any other new calls.

If a user is in wrap-up time or in mandatory call tagging when a call comes in and the user becomes available again...

The next call waiting will start ringing to the user's device.

Adele has just ended a call and is finishing up her one-minute wrap-up time to take notes. Afterward, she'll need to tag the call as her Admin enforces call tagging.


An incoming call has just come into the queue and is waiting to be dispatched to an available agent. As Adele becomes available, she will be included in the distribution.

If all users or teams assigned to a phone number are in after-call work (wrap-up time and/or mandatory call tagging) and there are calls waiting...

The calls will wait within the allotted queuing time established at each team level until a user within the team becomes available to answer the call. The call will pass through the distribution list.

It's 6 p.m. on a Friday - a high volume time of the day for food delivery-based company Foodaroo.

Their order hotline number is ringing non-stop and there are many calls in the queue waiting to be answered while most users are busy.

There are also three teams (Team UK, Team USA, Team on-call) assigned in the call distribution of the line with a three-minute queue time, leaving an opportunity for more users to answer the calls.

At the moment, every user in Team UK is in wrap-up time, so the call will now ring to any available users who come back from after-call work, making its way down through the distribution list.

If all users or teams are unavailable or offline and there are calls waiting...

The call will skip unavailable users and teams and move through the queue and ring only to available user's devices.

Foodaroo's order hotline number is winding down and many users are signing off for the day as their shift has come to an end.

There are a few straggler calls coming through only to the available users (skipping completely any offline or unavailable users in each team in the call distribution).

If a user is logged into multiple versions of the application (desktop, CTI, or mobile)...

The call will ring to the agent on all applications at the same time.

Tom's sales team works on the go and are often signed into the mobile application as well as the desktop application for ease of access and to ensure they don't miss a call.

An incoming call is coming into the Sales Line and two users are currently online and signed in to both applications. The call will ring to both the desktop application and the mobile app at the same time.

Ringing Rules for Numbers

In addition to setting the ringing rules for your teams, each Aircall number has two additional options you can toggle on and off.

Respect Queuing Time (RQT)

Enabling the Respect Queuing Time feature for a number allows you to make sure calls stay in the queue for the full ringing time set for each of your teams assigned to the number, regardless of the agent status.

Priority Line

Enabling the Priority Line feature for a number allows you prioritize calls to that number over calls from non-priority lines.

Using Additional Devices with Aircall Routing

Some users might frequently step away from their desks and use our mobile applications or our forward-to-device feature. In these instances, as long as the user is connected to the application and set as available, calls will ring to all devices connected in the same logic.

Keep in mind that using the forward-to-device feature is intended for those who do not wish to use the mobile or desktop applications, but rather to rely on their mobile carrier service. It will not be possible to use this feature with the mobile application activated at the same time.

Call Routing Variables

The efficiency of your call center can vary on a few overarching variables based on your specific use case:

  • Number of agents staffed

  • Specialized agents with specific skill sets (specializations, languages)

  • Volume

It’s important to take a step back to look at the advantages and disadvantages of using teams vs. users, as well as utilizing the different ringing rules made available through Aircall.
