Failure
Handing | Specifies the behavior when a fax tone is detected but the treatment fails for any reason. The behavior can be:
• Disconnect—Release the call.
• Continue—Continue (default)—Continue to process the call. The default setting is Continue. | Tone Treatment | Specifies the treatment taken when the fax tone is tones are detected, which can be: - Disconnect—Disconnect the call when the fax tone is tones are detected.
- Fallback To G711—Fall back to G.711 when the fax tone is tones are detected.
- Fallback To G711Allow Peer To Negotiate Fax Relay —On —On detecting the fax tonetones, the SBC initiates signalling of transcoded calls to transition to G.711. This happens when the current codec is not already G.711. After transiting transitioning to G.711, the SBC allows the peer to re-Invite invite to T.38 transitions.
- Fax Relay—Switch to fax relay (T.38) when the fax tone is tones are detected.
- Fax Relay Or Fallback To G711—Switch to fax relay (T.38) if supported, or fall back to G.711 when fax tone is tones are detected.
- Ignore Detect Detection Allow Peer To Negotiate Fax Relay—Accept a T.38 reINVITE re-invite (either from a calling party or a called party) without detecting the fax tone.
- None (default)—Do nothing when the fax tone is tones are detected.
- Notify Peer—For SIP signaling, notify the peer when the fax tone is tones are detected and let the peer decide the next action.
The default setting is None. | | Honor Tone Detection | Enable this option for G.711 to G.711 transcoded calls to cause the SBC to initiate a fax re-invite upon fax tone detection when the Tone Treatment configuration is either Fax Relay Or Fallback To G711 or Fallback To G711. When disabled, the SBC ignores the fax tone. This option only applies to a G.711 codec without silence suppression. |
