asterisk users - Jan 2012 - Is it valid to Dial(DAHDI/g0/12345wwwww88888888) on an ISDN trunk?

I am trying to collect information regarding a bug report for Elastix
(http://bugs.elastix.org/view.php?id=1146). In this bug, an user has
asterisk-1.8.7 and dahdi-2.4.1.2. He is trying to make an outbound call through
an ISDN trunk, by placing
Dial(DAHDI/g0/12345wwwww88888888) in order to send 12345, then wait a period,
then send 88888888. I am still waiting for a response on what particular
telephony card he uses, and the kind of ISDN setup (T1/E1/BRI) being used, but I
want to know: Is this
dialstring expected to work with an ISDN trunk? If so, are there any
configurations that might cause it to stop working? The user claims that this
same dialstring worked with Elastix 1.6 which had dahdi-2.2.0.2 and
asterisk-1.4.26.1.

Some additional information: the user reports that the dial attempt fails with
hangup cause 28. From

:

Code No. 28 - invalid number format (address incomplete).
This cause indicates that the called party cannot be reached because the called
party number is not in a valid format or is not complete.

Is it actually possible that the code is trying to send a string of 'w's
through the ISDN link? Or am I misunderstanding?

"w" is only allowed as part of the dialed TN on FXO and FXS ports.

Dial the TN normally, use the D() option to Dial to send post answer digits.

i.e. Dial(DAHDI/g0/12345,240,D(wwwww88888888))

See "core show application dial"

I'm using 'w' to force sending the 'sending complete' IE in
an ISDN setup message.
But I don't know the usage of multiple 'w' in the  dialstring.
