Remote Phone Book
The remote phone book is a centrally maintained phone book, stored on the remote server. Users only need the access
URL of the remote phone book. The IP phone can establish a connection with the remote server and download the
phone book, and then display the remote phone book entries on the phone.
Yealink IP phones support up to 5 remote phone books. The remote phone book is customizable.
Note
For T40P/T40G/T23P/T23G/T21(P) E2/T19(P) E2 IP phones, we recommend you to download less than 3000 remote contacts
(including one name and three numbers fields) from the remote server. For other IP phones, we recommend you to down-
load less than 5000 remote contacts (including one name and three numbers fields) from the remote server.
