For using phone there are the following, typical use scenarios:

phone in the dialog application
With phone in the dialog application you can check addresses that have been entered and changed. During the normal maintenance process you can check directly on the screen whether the telephone number is current. If necessary, you can correct and complete the telephone numbers in a dialog. If unambiguous automatic assignment is not possible, user support is conveniently provided. If e.g. resulting from the comparison, several equally probable assignment possibilities contain the risk of wrong decisions, all of the addresses/telephone numbers that could be considered are displayed. The user can then make the appropriate selection. Due to the error-tolerant search, even with the entry of incomplete or erroneous spellings, suggestions for possible, valid street spellings/addresses/telephone numbers are displayed. Therefore a conclusive clarification of the case on the screen is possible as long as the input reference is still available.

phone in the batch application
With phone in the batch application there is the possibility, in the context of an update, to check all movements and, if necessary and possible, to check them. Due to direct access to the phone files, no sorting of the input addresses is required. However, it is recommended for performance reasons (according to postal coen/city, street). If address data is not identifiable due to a recording error, this information can be made available from the user's framework program in the form of error lists and input statistics for corrections or evaluations.

Uniserv provides the batch tool phone as a supplement to the online components. It can be used for:

• the mass assignment of telephone numbers in a batch operation for first-time supplementing and correction of the files. The high performance connected to that allows the assignment in an acceptable length of time even for large databases (10 to 80 million addresses) 
• periodic maintenance of changes in telephone numbers of customers or prospects in the address file. The telephone server gives you targeted information on which addresses are to be checked. Without having to conduct a complete new evaluation of the files, you can maintain your addresses so that no change messages must be initiated.
