asterisk users - May 2012 - Why SendDTMF is not working?

Hello,

I am having a problem with SendDTMF - it is not sending the numbers
properly during the phone call.. I want the numbers key to to be
pressed/sent automatically after 3 seconds during a phone call.

I use software phone to test it... when I dialed 501, I cant hear anything
for about 10 seconds (this is because of SendDTMF)  and then I can hear the
operator saying to enter the numbers but SendDTMF already did it?!

Asterisk server are connected to voip.ms provider.

I have spent many hours trying to get to work, how to fix this issue?

See the configuration and debug log below:

extensions.conf
===============[test]
exten => 501,1,Set(CALLERID(num)=004471XXXXXXX)
exten => 501,n,Dial(SIP/+44797XXXXXX at voipms,30,M(sendnumber)t)
exten => 501,n,Hangup()

[macro-sendnumber]
exten => s,1,Wait(3)
exten => s,n,SendDTMF(www0w7w8w8wXwXwXwXwXwX)

sip.conf
=========[general]
context=default
tcpbindaddr=0.0.0.0
dtmfmode = rfc2833
register => xxxxx:vxxxxx at london.voip.ms:5060

If you need any more information or debug, let me know!

Thanks!

Log the actual DTMF to your console, set in logger.conf:

console => something,something,dtmf
                                ^^^^

Then try again and check if you see the actual DTMF. If you do and it 
still doesn't work, try

dtmfmode=inband

for your voipms peer.

rfc2833 has been working always unreliable for me.

Also, I'm doing DTMF like this:

exten => 5000,n,Dial(SIP/123456 at provider,,D(wwwwww1ww2ww3ww4))

Just use more w's to generate your 3 seconds pause. No need for SendDTMF.

For more debugging just call yourself on your UK mobile from a softphone 
and press digits and watch the console and listen on your mobile if you 
hear the DTMF.

PS: You are only allowing the GSM codec for your voipms peer, why? Maybe 
that is the reason why DTMF isn't working properly. You should try alaw 
and ulaw, respectively both.
