To set the Detection Break Power Threshold:.Telif.InteropDtmfDetectionRiseTimeCriteria creating a configuration script containing the configuration parametersįor more details on the following parameters, refer to the DGW Configurationn Guide - Reference Guide published on the Media5 Documentation Portal.Of the configuration can only be completed with the configuration parameters by : Top Basic DTMF Tasks Configuring DTMF Transport for all EndpointsĪlthough the services can be configured in great part in the Web browser, some aspects ISDN endpoints are normally configured to useĪn Out-of-Band transport method for DTMF transmission. The DTMF Out-of-Band (using either SIP or RTP) transport method is configurable by endpoint, orĬan be selected for all the endpoints of the unit. The Mediatrix unit receives and sends Out-of-Band DTMFs as per ITU Q.24. Such a mechanism is known as Out-of-BandĭTMF. The DTMF sequence back by regenerating the true tones. Solution is to send this information as a separate packet to the other endpoint, which then plays

Tones (such as DTMF) this distortion means the receiver may no longer recognize the tones. For normal speech this is insignificant and becomes unimportant. They lose information from the incoming voice stream during the compression and decompression Transport method can only be used if the SIP peer supports the method, otherwise the DTMFīecause some compression codecs such as G.723.1 and G.729 effectively distort voice because

Two different streams where the voice is sent over RTP, but DTMF is sent either in RTP or SIPĭepending on the chosen transport method ( Out-of-Band using RTP or Out-of-Band using SIP. When using the Out-of-Band transport method, the DTMFs and the voice are transmitted in
