DTMF Parameters |
| |
Duration | 60 – 3000 | When DTMF: Out of Band is selected, |
(DTMF) | ms | this setting determines how long each |
|
| DTMF digit ‘sounds’ or is held. Default |
|
| = 100 ms. Not supported in 5.02c BRI |
|

DTMF | Out of | When DTMF Out of Band is selected, |
In/Out of | Band, or | the MultiVOIP detects DTMF tones at |
Band | Inband | its input and regenerates them at its |
|
| output. When DTMF Inband is |

|
| through the MultiVOIP unit as they are |

|
| Out of Band” can be checked or |
|
| unchecked. |
Out of Band | RFC 2833, | RFC2833 method. Uses an RTP |
Mode | SIP Info | mode defined in RFC 2833 to |
|
| transmit the DTMF digits. |
|
| SIP Info method. Generates dual |
|
| tone multi frequency (DTMF) tones |
|
| on the telephony call leg. The SIP |
|
| INFO message is sent along the |
|
| signaling path of the call. |
|
| You must set this parameter per the |
|
