Symptom
After attempting to import a list of contacts into Aircall, an error is displayed that states, "X of your contacts contain missing information and could not be processed."
Cause
This error is displayed when the phone number(s) for some of the contacts are not able to be verified. This can occur when the phone number field is left blank, when the number is not a valid telephone number, or when the number formatting is unable to be determined.
Solution
To ensure all contacts are appropriately uploaded to Aircall, please make sure that each contact has a valid phone number listed, and that it is listed in the E164 format. Although other number formats may work in some cases, using the E164 format is strongly recommended to ensure that your contacts are saved correctly.
