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 IP 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 extension.
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=sendonly) per
RFC 2543 is used in the INVITE message when placing a call on hold.
Capturing packets after you disable the RFC 2543 Hold feature. SDP media connection address c=0.0.0.0 per RFC 3264 is
used in the INVITE message when placing a call on hold.
