The SIP protocol includes a normalized mechanism to allow any client (a telephone in
VoIP being an example of a SIP client) to monitor the status of another device.
If Device A client wishes to be informed of changes to the status of Device B, it will
send a SUBSCRIBE request directly to Device B or to a server that is aware of Device
B's status. If the SUBSCRIBE request is successful, each time Device B's status
changes, Device A will receive a SIP NOTIFY, a message indicating the change in status
or presenting information about the event.
When one device subscribes to another, it will be informed when an event occurs.
Example
Onlining of contacts that it is looking for.
Select this option to enable the extension.
