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?
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.
See https://issues.asterisk.org/jira/browse/ASTERISK-19176

If I understand correctly, the support for 'w' in the dial string was removed
when refactoring the PRI signaling code. Was this deliberate, or unintentional?
I believe it should be added back for consistency with other signaling types.
