ISDN Redial Limitation: Failed Call List Full
The Redial Limitation module maintains a list of unsuccessful calls. This list has become full. Calls will not be placed until there are free entries in the list.
Check your equipment to find out why calls are failing. Increase the size of the failed call list in System Configuration. Wait for the timer to elapse to free up entries in the list. (The list is cleared after a certain period defined by the homologation requirements of your area.)
