Asterisk dtmf tone. To do that, also set the 'digitdetect' option.


  • Asterisk dtmf tone The noises are akin to button press tones, are very loud and a significant annoyance. The better substitute are ‘rfc2833’ and ‘info’. I think that depends on how you're playing DTMF tones within Asterisk. Inband DTMF as audio tone does not work reliably unless the Asterisk codecs setting is ulaw or alaw (G711). See also. Testing the switchboard from a normal phones works. DTMF events are conveyed via the ChannelDtmfReceived event. Female voice is known to once in a while trigger the recognition of a DTMF tone. Asterisk DTMF; Asterisk cmd SIPdtmfmode: Change the DTMF type of an outbound SIP call; SIP DTMF Signalling; Asterisk SIP channels In DTMF debug I can see the asterisk reaction to incoming INFO or rfc2833 events, but nothing happens when inband tone is coming. Seems like asterisk does not "hear" the line at all. To do that, also set the 'digitdetect' option. In order to avoid this behaviour in Asterisk, what you can do is to modify the frequency of the DTMF tones Asterisk expects, so that the true DTMF tones are not recognized and therefore let alone by the DSP module. For tones utilized in the case of sending call address data to setup the call, the answer is dependent on the channel driver. Testing the switchboard using 7777 works. You have to purposely misconfigure things to cause it to not get stripped. Every since a month ago, seemingly out of the blue, the switchboard does not recognise DTMF tones any more from mobile phones. The event contains the channel that pressed the DTMF key, the digit that was pressed, and the duration of the digit. IE: DTMF is actually inband but you configure it for RFC2833. When sent as audio, only uncompressed codecs such as G. If digit detection is disabled, DTMF will not be Inband DTMF as audio tone does not work reliably unless the Asterisk codecs setting is ulaw or alaw (G711). Disabling tone dialing using this option will not disable the DSP used for DTMF detection. I couldn't find any information about modules requeried to detect inband DTMF. For analog lines, inband audio is the only possible means to transmit DTMF. We have an issue with several Cisco SPA512G phones connected to an Asterisk platform where several users hear loud, random beeps during calls to external recipients. If digit detection is disabled, DTMF will not be . If properly configured then Asterisk will always strip and regenerate the DTMF tone. 711 (alaw and ulaw) can carry DTMF reliably. dialmode - R/W Pulse and tone dialing mode of the channel. eqtg fqi vaqqw tcfp kgxkh uec xccrnj yjjukk hgks mbkvae
