[asterisk-users] Asterisk / PRI and Outbound Overlap Dialing

I am trying to setup Asterisk to act like a PBX connected via a PRI gateway
to a voice netowrk where Asterisk is doing outbound
overlap dialing for calls that terminate via that PRI. AFter researching
through the archives and online dcocs, I thought I had
everyting setup right, dialplan configured for '_X!' and the
'overlapdial=yes' in the chan_dahdi.conf file, but when I try and
make a call, while the first digit triggers the outbound SETUP message,
that SETUP message always includes a 'Sending Complete'
parameter and any subsequent digits received from the originaing client
seem to be getting ignored as opposed to sent over in
subsequent ISDN INFORMATION messages.

Any idea what I might be missing here...i did restart both DAHDI and
Asterisk after making the changes to support overlap.

Logs and snippets are below..

Thanks
matt

Where is this option set in the chan_dahdi.conf file?  To have any effect
on a particular channel the option
MUST be set before the channel line that creates the channel.

[channels]
context=incoming
switchtype=euroisdn
signaling=pri_cpe
overlapdial=yes

; All options currently set are used to create the specified channels on
the next line.
channel=1-15,17-31
; Any options set AFTER the channel line above DO NOT affect those channels.

context=other

Thanks Richard, That did the trick. I had the 'overlapdial=yes' line
farther down in the chan_dahdi.conf file. Moving up before the channel line
worked.

Appreciate the help.
