Description

Failure Handling

Specifies the behavior when a modem tone is detected but the treatment fails for any reason. The behavior can be:

  • Disconnect—Release the call.
  • Continue (default)—Continue to process the call.

 

Tone Treatment

Specifies the treatment taken when modem tones are detected, which can be:

  • None (default)—Do nothing when modem tones are detected.
  • Notify Peer—Notify the peer when modem tones are detected.
  • Disconnect—Disconnect the call when modem tones are detected.
  • Fallback To G711—Fall back to G.711 when modem tones are detected.
  • Apply Fax Treatment—Treat the modem tone as a fax tone, and apply the fax treatment for the selected codec.

 

Honor Tone Detection

Enable this option for G.711 to G.711 transcoded calls to cause the SBC to initiate a re-invite upon modem tone detection when the modem Tone Treatment configuration is Fallback To G711.

When disabled, the SBC ignores the modem tone.

  • Disable (default)
  • Enable

This option only applies to a G.711 codec without silence suppression.

Note:

For G.711 calls, Notify Peer and Disconnect require a compression resource to be allocated.
