Other Issues
The difference among user name, register name, and display name
Both user name and register name are defined by the server. User name identifies the account, while register name
matched with a password is for authentication purposes. The display name is the caller ID that will be displayed on
the callee’s phone screen. Server configurations may override the local ones.
On code and off code
They are codes that the IP phone sends to the server when a certain action takes place. On code is used to activate
a feature on the server side, while off code is used to deactivate a feature on the server side.
For example, if you set the Always Forward on code to be *78 (may vary on different servers), and the target number
to be 201. When you enable Always Forward on the IP phone, the phone sends *78201 to the server, and then the
server will enable Always Forward feature on the server side, hence being able to get the right status of the exten-
sion.
For anonymous call/anonymous call rejection feature, the phone will send either the on code or off code to the
server according to the value of Send Anonymous Code/Send Rejection Code.
The difference between RFC 2543 Hold enabled and disabled
Capturing packets after you enable the RFC 2543 Hold feature. SDP media direction attributes (such as a=se-
endonly) per RFC 2543 is used in the INVITE message when placing a call on hold.
