[asterisk-ss7] No audio using libss7 over E1

Wow.
I thought I had it fixed when I picked up misaligned CICs on my second
E1 port but it has not made any difference. Still there is no audio
making it back to the calling party who's called in via the SS7 link.
I did find that with 'ss7_explicitacm=yes' in my chan_dahdi.conf the
call would be answered by Asterisk and then hung up. It seems that for
the call to stay active I had to remove 'ss7_explicitacm' from my
config; but still there is no audio.
I enabled "monitor()" in my dialplan and I can hear that my test music
on hold is being played back but it is not making it to the calling
party called in on the SS7 link.
My provider sent me a document showing his channel numbers and his
assigned CICs. I then added to the document and listed my Dahdi ports
and corresponding CICs to assist with me aligning my CICs with his. So
far from what I can tell it looks fine?
Some posts seem to indicate that there may be a problem with
Asterisk-1.6.2 and that I should try Asterisk-1.6.0, or even 1.8.x? My
updated config files have been included below. I've also asked my
provider to enable the "Continuity Check" suggested by Gustavo but am
waiting for them to confirm. Your assistance is greatly appreciated!
