A remote phonebook is placed on a server, while a local phonebook is placed on the IP
phone flash. A remote phonebook can be used by everyone that can access the server,
while a local phonebook can only be used by a specific phone itself. A remote
phonebook is always used as a central phonebook for a company. That is, every staff in
the company can load this phonebook and each time they are trying to open a remote
phonebook, the data is passed real-time from the certain server.
Both user name and register name are defined by the server. A user name is used to
identify the account while a register name matched with a password is used for
authentication if the server requires. Display name is the caller ID that will be displayed
on the callee's phone LCD screen. Some server configuration may override the local
configuration.

additional string ―reboot=true‖. The message is formed as shown:
NOTIFY sip:<user>@<dsthost> SIP/2.0
To: sip:<user>@<dsthost>
From: sip:sipsak@<srchost>
CSeq: 10 NOTIFY
Call-ID: 1234@<srchost>
Event: check-sync;reboot=true
A factory reset can restore the original password. Please try to long press the OK key
when the IP phone is idle, which should lead you to make a factory reset.
