[asterisk-users] Why SendDTMF is not working?

[Shahid H]

Thanks for the suggestion Markus. Here what I did:

In the logger.config I have added 'dtmf':

console => notice,warning,error,dtmf

and then in sip.conf:

allow=ulaw
allow=alaw
; allow=gsm
dtmfmode=inband

I've added a test to call my mobile:

exten => 123,1,Dial(SIP/+4477XXXXXXX at voipms,,D(wwwwwwww1ww2ww3ww4))
exten => 123,n,Hangup()

then restarted asterisk and logged into console (asterisk -r)

I've call my mobile using softphone, I did not see 1,2,3,4 digits being
sent on the console but I can hear broken/unclear DTMF on the mobile...

however when I press digits on the softphone I can hear DTMF clear how it
should be on my mobile and on the console it is showing DTMF:
