Bear in mind that invitations to an Aircall account are sent from the email address
noreply@notify.aircall.io and your email account should allow you to receive emails from this domain.
Invitation emails will look like:
This Accept Invitation button will lead you to a URL that starts with the following
https://brcs2zd1.r.us-west-2.awstrack.me/L0/https:%2F%2Femail-verification.aircall.io%2Fauth%2Fv1%2Fusers%2Fidentities%2Fconfirmation%3Fpayload=
⚠️ In case you receive an error when clicking on the Accept Invitation button, please validate if the URL in your Browser starts by a different domain, such as:
https://us-email-isolation.prod.fire.glass/https://clicktime.symantec.comhttps://<region>.safelinks.protection.outlook.com/https://urldefense.proofpoint.com/https://protect.mimecast.com/s/https://<region>.secure-web.cisco.com/https://global.sitesafety.trendmicro.com/urlcheck/https://linkprotect.cudasvc.com/https://gateway.zscloud.net/https://app.ironscales.com/link/https://companyname.avanan.net/https://email-security.sophos.com/
If this is the case, then it means your security tools (such as content blockers to avoid phishing or malware) are blocking Aircall's Accept Invitation URL. You should contact your IT team.
