What the detail says

The detail explains the occurrence; it can read, for example:

• Billing is past due, so calls to customers are paused until the invoice is paid. Customers can still call you.
• Billing is past due, so paid templates are paused until the invoice is paid. Free replies inside the customer’s 24-hour window still send.
• Billing is past due, so the call was ended. Calls to customers resume once the invoice is paid.

Handling it

A payment is needed: top up the wallet or settle the invoice, then retry.
