[Asterisk-Users] E&M DID config question

I am trying to make an in/out trunk group comprised of 4 DS0's using
E&M Wink signalling.  The first four channels of a DS1 on a T100P
are being used for the group.  Outbound calls work fine, but inbound
calls fail.  The other 20 DS0 channels are used for a PRI. Does the
configuration shown below look okay?  I've tried setting 'immediate => yes'
without success, but it doesn't seem to make any difference..

It seems like Asterisk never gets any digits from the upstream switch. I don't
think the upstream switch gets a wink from Asterisk, but I am not sure.

Here's what the console log shows.

-- Starting simple switch on 'Zap/1-1'
   File chan_zap.c, Line 3772 (ss_thread): getdtmf on channel 1: Operation now in progress
== Unknown extension 's' in context 'default' requested
-- Playing 'ss-noservice'
-- Hungup 'Zap/1-1'

Incidentally, inbound calls on the PRI are immediately disconnected when
inbound caller-id info is present. The E&M trunk group is an attempt to
workaround this problem.
