[asterisk-users] Dial command option D(digits)

[Jerry Geis]

I am using asterisk 1.2.9.1.

I had been using the option D to send some dtmf tones after the call is 
answered.

This doesnt seem to be working for me now.
I am using and IAX2 connection from one machine to another.
my extensions.conf has:

exten=>  57,1,Dial(IAX2/boxa_to_boxb/597,,tD(101))

When I answer phone 597, I do not hear the DTMF tones 101 being pulsed out.

On the CLI I see

Sending DTMF (101) to the called party.

Am I not doing something correctly?
