Local Directory
Yealink phones maintain a local directory that you can use to store contacts. The local directory can store up to
1000 contacts and 48 groups (47 groups for CP920 phones).
Contacts and groups can be added either one by one or in batch using a local contact file. Yealink phones support
both *.xml and *.csv format contact files, but you can only customize the *.xml format contact file.
