Overview

You want to (re)assign multiple numbers via single batch operation and keep getting the "Unexpected error has occurred - please contact your system administrator" error.

Solution

When you clear old assignments in batches, sometimes the information is not updated correctly, leading to the observed error with batch assignments. In such cases, try assigning numbers manually, not in batches.

If this fails as well, or the numbers list is too long, open a ticket with Support, making sure to describe the issue and any symptoms you observe, things you tried, and add a list of numbers and assignments that are failing.

Based on the troubleshooting the Support team will either take action to fix the issue on our side, or reach back with findings and any next steps required from you.

Verification

Once the root cause is fixed, try to replicate the issue to confirm that it is no longer there.
