Outbound 8x8 SMS messages not being received

These users have been unable to send SMS messages successfully to some mobile number destinations. The observed impact is found only in enabled and assigned numbers to an already approved SMS Campaign registry. The impacted numbers can be resynchronized via self-service by disabling and re-enabling SMS for the affected users in your admin console. This knowledge article can guide you through the process. 8x8 is exploring with our carriers how to reduce the time to process the resynchronization of the impacted numbers. If you plan to enable more than 48 phone numbers for SMS please be aware that extra information is required after an SMS Campaign is approved. Details on this topic can be found in this FAQ. Only after submitting the extra information can numbers beyond the first 48 be resynchronized.If you need assistance on this matter please contact support.
