[Asterisk-Users] Direct Dial In - second try

[ChB]

Hi all,

I have an asterisk-server (cvs-head from august) connected to a
carrier's switch (DMS/Euroisdn) via a te410p, and I am having problems
with DDI (standard 'official pstn' number plus extra digits for
'internal' use)

Basically, when the entire number (including the extra digits) is
dialled via a redial or a programmed key, I see the entire called party
number (including the extra numbers) in * debug. However if I dial the
number manually (digit for digit) the carrier puts it through before
I've  finished dialling (after 10 digits), and I never see the whole DDI
dialed.

Since I want to be able to use numbers with and without DDIs, I can't
tell the carrier to raise the minimum level to more than 10 since
numbers dialled without DDIs would never be passed.

The carrier is telling me to wait a second or two before seizing the
call, and that any additional digits received would be passed in the
isdn protocol. My understanding is that the called party number would be
retransmitted, including the DDI. (Wait in the dialplan doesn't work, as
the call is already "taken")

Does anyone have any idea why this is not working? Is the carrier right?
This doesn't seem to be such an odd feature that nobody else would use
it ;-), so please leave a comment, even if it works for you out of the
box without fuss. Your help is highly appreciated, thanks!

I have included two traces. The first is the number dialled with a speed
dial key, the second is exactly the same number dialed manually. 

Best regards
Christian
