| Problem Summary | Dual-Tone Multi-Frequency (DTMF) tones are not recognized. |
| Error Message | None |
| Possible Cause | If using ASR, and the caller is coming from the PSTN, the gateway dial-peers may be incorrectly configured. |
| Recommended Action | Possible Solution: In Unified CVP, there are two VoIP dial-peers involved in the call: One to go from the gateway to the Unified CVP H.323 Service and one to go from the Unified CVP H.323 Service to the IVR gateway.
Each of these dial-peers must have the following attributes to be recognizabled correctly by DTMF:
|
| Release | Release 7.0(2) |

| Possible Cause | If using Scansoft ASR, the DTMF payload type is incorrectly configured in Scansoft. |
| Recommended Action | In Scansoft config file C:\Program Files\ScanSoft\SpeechWorks OpenSpeech Media Server\Server\config\OssServer.cfg, change the following value from 96 to 101: server.transport.dtmfPayloadType VXIInteger 101 |
