33. BLF, a typical feature supported by PCM/TDM PBX and Key Telephone Systems, is also supported on SIP Extensions.
In PCM/TDM PBX and Key Telephone Systems, this feature is typically used by the Operator to monitor the status of another
extension, i.e. whether it is available, ringing or busy. The status of the other extensions is indicated on the special function keys
configured on the Operator's console. This helps the Operator decide whether to place the call, or transfer the call to that exten-
sion, or pick up the call ringing on that extension.
With BLF Subscription enabled on the SIP Extension, the user can monitor the status of another extension, device or number
within the same Proxy Domain.
