The cloud phone book allows you to create a list of contacts using the MyIntegra portal. These contacts are then sent over to the VoIP phone so you can easily dial contacts which are called frequently. The cloud phonebook feature works great with our handsets such as the A10, B20, C30 and D40. Though the phonebook can be set up manually with other VoIP phones such as Yealinks. However, this will need to be done manually using the LDAP settings found on our portal under Hosted VoIP >Manage >Features >Call features >Cloud Phonebook >View Manual Settings. These details will need to be manually set in the phone via the web interface.
