asterisk users - Nov 2005 - Sending DTMF tones after answering on an IAX channel

Hi,

I'm trying to send some DTMF dialtones (for an extension on the other end).
My call is done from a Zap channel, to Asterisk, throught an IAX provider,
to a PSTN line in some university.

The phone number I am trying to reach is 555-555-5555 exten 1234.

What I did is an
Exten => 201,1,Dial(IAX2/provider/5555555555||D(1234))

Well, that doesn?t work.  The other end doesn?t seem to accept the DTMF
tones.  Maybe Asterisk is sending them too quickly (how to I put a pause in
between?)

I also tried using pauses (Dial/IAX2/provider/5555555555wwwwwwwwww1234) But
my outgoing provider tells me it's "circuit busy")

Any clue or me?  Just calling 555-555-5555 is fine, but I have to put in the
extension manually.  No good for my needs.

It could be that the audio codec you are using is munging the tones 
into an unusable form....
