This action retrieves the historical statistics for a given ISDN Signaling Group in the SBC. The collections are over 1 hour intervals for a period of 1 day, thus giving a maximum of 24 historical records.
The current interval is always the resource with ID 1. There will be a maximum of 25 rows returned for a lookup, where the row with ID 1 is the current interval being collected and the rows with ID 2-25 are the historical collections.
If no ID is specified, a listing of all collections will be returned along with their associated IDs. These identifiers can be used to get the individual resource element values.
