This object creates a DTMF profile, which maps one or more digit key sequences to actions and associated scripts for take back and transfer features such as blind transfer, consultative transfer, and conference and transfer.
To View and Edit DTMF
On SBC main screen, go to Configuration > Profile Management > Category: Media Profiles > Codec Entry >DTMF.
Select the desired Codec Entry from the drop-down list to view its respective DTMF parameters.
The DTMF window is displayed.

Relay
| The possible values are: none—Leaves the DTMF tones in-band as encoded audio.outOfBand—Applies to -to-SIP or -to-H.323. Carries DTMF in the signaling protocol.rfc2833—Applies to -to-SIP, -to-H.323, or -to- . Encodes DTMF into RTP using a format and payload type distinct from the audio encoding.eitherOoBOrRfc2833—Out-of-Band and RFC 2833 are equally received and only one is transmitted. The one transmitted is the one preferred by the peer or RFC 2833 as the default.obothOoBAnd2833—Out-of-Band and RFC 2883 are equally received and both can be transmitted. This option would normally be used only in the case where the OOB DTMF signaling is absorbed and not regenerated. For example, the OOB DTMF might go to an application server that needs to detect the DTMF for control purposes but does not process RTP and the 2833 DTMF would go to the destination media address as part of the RTP stream.
The default setting is None. | Remove Digits
| Enables the removal of DTMF digits from the media stream. This applies only if DTMF relay is configured as Out-of-Band or RFC 2833. The default setting is Enabled. |
