Setting up your phone number for optimal success is a key step in getting your users ready for Aircall. Once you’ve set up your business hours on your phone numbers and your call distribution, you can take a closer look at understanding Aircall routing through this guide.

What is Call Routing?

Call routing is an automatic call distributor tool that allows you to route calls to your phone numbers and then to a specific user or team based on pre-established business 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 and on the availability of the users assigned to the phone line. If your phone number is closed, or your users are not available to take a call, then the call cannot be routed accordingly.

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 back up or 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 in 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:


  • 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, outside of their set working hours, or set to Do not disturb


  • the user is in-call

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


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

  • the user’s availability 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 agents or teams you have assigned to a phone number, the likelier 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 and the call will ring to their Phone application. This includes all applications they are signed into as well as any forwarding devices that are enabled on the 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 a new call is coming into the line, the user will be included in the distribution as soon as they are available again.

This also includes when a new call is ringing and a user was previously engaged in a call, in wrap-up time, or still in mandatory tagging, Aircall will then include the user in the distribution once they become available again. Users 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, there must be at least one user currently busy for a call to wait within the queue. If no users are busy, the call will skip to the next position in the queue.

Depending on the workflow you’ve set up for your number, it 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

In Aircall, you’ll have two standard ringing options to choose from when utilizing a Team. If you have assigned one user to a phone number, then the ringing rule is automatically set by default to 25 seconds (around five rings). This applies to individual users within teams as well. Unfortunately, it is not possible at this time to adjust this ringing time by either increasing or decreasing so it will need to be taken into consideration when you’re setting up your phone number and specific team queuing times.

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.


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).


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).

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

Respect Queuing Time (RQT)

Enabling the Respect Queuing Time allows you to configure your calls to stay within the maximum queue time established for your team that is assigned to the phone number regardless of the agent status.

The most important aspect to note of RQT is that the BUSY status is considered for neither RQT on or off as an agent may become available again to take a new call.

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.
