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