   MODULE  : ATBPbGI

   PURPOSE : This modul contains phonebook management functions using ATB.

   HISTORY:

     Oct 27, 2005	REF: OMAPS 48881 b-nekkare
      Description: PhoneBook: The modify option under phonebook doesn't 
                        work as expected.
      Solution :  Change is needed when we initially store the PB entry with 
                      a '+' and then we delete the '+' and resave the number again. 
	               If this is not done we would always end up preserving the TON 
	               as INTERNATIONAL type
