Why SendDTMF is not working?

[Shahid H <shahidh@xxxxxxxxx>]

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@voipms,30,M(sendnumber)t)

exten => 501,n,Hangup()

[macro-sendnumber]

exten => s,1,Wait(3)

exten => s,n,SendDTMF(www0w7w8w8wXwXwXwXwXwX)

sip.conf
