Note: If classification for a SIP request fails and the device is configured to reject
unclassified calls, the device can send a specific SIP response code per SIP
interface, configured by the 'Classification Failure Response Type' parameter
in the SIP Interface table (see 'Configuring SIP Interface Table' on page 207).
The flowchart below illustrates the classification process:
Figure 31-4: Classification Process (Identifying IP Group or Rejecting Call)
Notes:
• Incoming REGISTER messages are saved in the device’s registration
database and sent to a destination only if they are associated with a
source User-type IP Group.
• The Classification table can also be configured using the table ini file
parameter, Classification or CLI command, configure voip > sbc routing
classification.
