User manual

This will greatly reduce the heavy burdens on the server. For example, if you have 10
extensions, normally you will have to subscribe with the server for 10 times from the first
extension number to the last. However, if you specify a BLF List URI including these 10
extensions and name it “Sales”, you will only need to subscribe “Sales” with the server,
which happens only for once.

11. Q: What is “SCA “feature used for?
A: The Shared Call Appearance feature allows a line that is an address-of-record, to place and
receive calls on multiple endpoints. Although the endpoints each register with the
BroadWorks server with different unique URIs, the call appears to the other party to be
originating from or terminating at the same line, no matter which of the endpoints sharing
the line is used.

12. Q: What is the difference between remote phonebook and local phonebook?
A: Remote phonebook is placed on a server, while local phonebook is placed on the phone
flash. Remote phonebook can be used by everyone that can access the server, while local
phonebook can only be used by a specific phone itself. Remote phonebook is always used as
a central phonebook for a company. That is, everyone in the company can load this
phonebook and each time they reach the remote phonebook, the data is passed real-time
from the certain server.
13. Q: What is the difference between user name, register name and display name?
A: Both user name and register name are defined by the server. A user name is used to
identify the account while a register name matches with a password which is used for
authentication if the server requires. Display name is the caller ID that will be displayed on
the called party. Some servers also define the display name so this parameter set on the
phone may not take effect.
14. Q: Is there a SIP message that can make the phone reboot?
A: Yes. The message format is like this:
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
