Saving and reading persistent information from ECR

CallQueueSetPersistentProperty:

This block can be used to save values into the internal persistent data table. To save multiple value into the database, more than one block needs to be chained.

Group	A data group value groups multiple key/value pair together like a category. This value can have any value. There are not predefined group categories.
Key	Key entry for each key/value pair
Value	Value for a specific key/value pair
Associated	These value can be empty or filled with any kind of data that should be associated with the value

Example:

1. Block: Group = "Announcements", Key = "1", Value = "Annoucement_Office.wav"

2. Block: Group = "Announcements", Key = "2", Value = "Annoucement_Holiday.wav"

3. Block: Group = "Announcements", Key = "3", Value = "Annoucement_Night.wav"

These 3 blocks create 3 entries in the database.

CallQueueGetPersistentProperty:

This block can be used to retrieve values from the internal persistent data table. To retrieve a specific value, all entries but "Value" needs to be filled with the filter criteria.

Example:

To retrieve one of the announcements from the upper example, data group and key needs to be filled with Group = "Announcement" and Key = "1", "2" or "3". The Value needs to be saved into a variable like "=ReturnValue".

If the saved value has been associated with a group, user, queue or call, these values needs to be set on retrieving the value from the database. Otherwise the value won't be found. If group, user, queue or call have been empty on saving the value, they have to be empty on retrieving the value too.
