I want to enter about 14,000 contacts in the address book also sort it as lists, so should I enter these contacts manually one by one which is not recommended or theres away to import theses data from Excel sheet or some thing like this?
I should also mention that there is an import function for distribution lists via the web interface. When you import a distribution list via the web interface it is similar to the format described at the link above, essentially we want to see one phone number per line in the import file.
