⚠️ Please keep in mind that calls will only reach a user via an extension when it is dialed on a number in which they are included in the call distribution. Should the user be Unavailable, or not answer, the caller will receive an automated message and the missed call will be assigned to the user within their To-do list. Currently, this automated message cannot be changed or customized.
Voicemails left on an extension
Voicemails left on an extension number will appear in the To-Do list of the phone application for the extension owner only.
If a voicemail is left on an extension that does not belong to a particular agent, they can still access the voicemail by searching in the History section of the phone application.
How can customers dial an extension number?
In order to use the extension feature, there must be either an audio widget for a number using Aircall's New Call Routing Solution (Smartflows), or an IVR or Welcome Message for a number using Aircall's previous routing, activated on the phone line.
When a customer calls a phone number, the customer should then dial the extension number while the audio widget/message is playing in order to be directly connected.
⚠️ Extensions cannot be dialed during the IVR widget for Smartflow numbers.
Please note that as extension numbers have three digits, and it is necessary that all three digits are dialed in order to be connected to the specific user.
